Hydra Seals – Celebrates 20 Years at the MGM!

Hi all…

We’ve had a hectic week over the Halloween

weekend. We took a little trip to Las Vegas to celebrate the business’ 20 years trading in Ireland. Over four days we each person traveled about 30 hours to and from the destination,  slept an average of 10 hours, and if it were still possible to re- mortgage in these days, it may well have been done. Thankfully everyone had a great time, and everyone arrived home safe and sound, in several pieces, in some cases.

We’ve posted a few photo’s below. Check them out.

HYDRAULIC HOSE REPAIR CHECKLIST

HYDRAULIC HOSE REPAIR CHECKS: WHAT TO LOOK FOR WHEN FIXING A HYDRAULIC HOSE

A hydraulic hose can blow or burt for a number of reasons… wear and tear, pressure wtc. However when replacing the hose and fitting new hose fittings, or even if using new connectors on a hose repair, we suggest you follow the following steps when undertaking the repair task.

  1. Always clean the area where fitting and hose connections meet. As we discussed previously, dirt and contamination should be kept out of the plant at all costs.
  2. If any adaptors are required, now is a good time to use. Replace with new if necessary and always adhere to the manufacturer’s specifications for the correct amount of torque..06---Ensure-Fittings-are-Correct
  3. Lay the hose assembly into routing position to verify the hydraulic hose length.
  4. Thread the hydraulic hose assembly onto the hose adaptor. It might require fitting the hose assembly directly to the hose fitting at this stage, if it aids in the ease of positioning the joint correctly. Without twisting the hose, thread the other end08---Fitting-Prior-To-Crimping.
  5. Properly torque both ends – again, subject to the hose manufacturers or hose distributors guidelines. Check the measurement with a calipers to see if the measurement is within the same guidelines.06---Checking-Connection-With-Calipers
  6. Inspect the hose for any leaks by running the plant or machinery for a duration of time. Check the contacts between the hydraulic hose fittings and the hose itself are good. Ensure that there is no air in the system – as it will impair performance and possibly damage the plant. Here you see the damaged hydraulic hose and the process of making the replacement hydraulic hose, with the first stage complete.

fire retardant hydraulic hose

Fire Retardant Hydraulic Seals & Hose

Fire Retardant Hydraulic Seals & Hose

The ISO has identified and classified 4 types of hydraulic fluids. This article touches on the importance of using fire retardant hydraulic seals.

There are several water based hydraulic fluids and most of them are used in the oil, mining, gas and construction industries. Most of these environments are hazardous, due to the volatile nature of the material or materials being mined/drilled for. As a result, the ISO has classified and set guidelines for the use of fire retardant hydraulic hose & seals, and the use of such materials. They are known as HFC, HFAE, HFAS and HFB.

According to an article on they state the ISO classification as

  • “HFAE, which includes oil-in-water emulsions, typically with more than 80% water content;
  • HFAS, which are synthetic aqueous fluids, typically containing more than 80% water;
  • HFB, which are water-in-oil emulsions typically containing more than 40% water; and
  • HFC (also known as glycol solutions, polyalkylene glycol solutions, and water glycols), which include water polymer solutions, typically containing more than 35% water”

HFC fuilds are the most commonly used fire resistant fluids in the world. We have found a really good article over at hydraulicspheumatics.com, and they a have a printable pdf document for your reading pleasure. We really recommend you have a read.

Hydra Seals are stockists of not high quality hydraulic seals and oils seals, but also a wide range of hydraulic hose. If you require fire retardant seals or hose, please contact us first with the specification of your requirement, we may be able to help you. Contact us here or over the phone at +353 1 8612700.

tapered roller bearings from hydra seals hose & bearings limited

5 Industries That Use Tapered Roller Bearings

5 Industries That Use Tapered Roller Bearings

One of the benefits of using Tapered or roller bearings is the ability to take heavy axial loads and can withstand radial forces in use with various machine types. They roller bearings can be found in many vehicles, as they are known to balance moving forces. They come in various forms and sizes and are compatible to various machineries that one could think of.

We could class roller bearings into one of four main types;

  • Single row tapered roller bearings
  • Matched single row tapered roller bearings
  • Double row tapered roller bearings
  • Four-row tapered roller bearings

Each one of these bearings have a specific application and are specific to various types of industry. The most common tapered bearing would be the single row tapered roller bearing and the double row tapered roller bearing. The tapered roller bearings are found in daily use in vehicles and moving machineries.

Tapered roller bearings popularity is due to the fact that they are easy to disassemble, and remove from machinery, so maintenance down time in minimised in highly dependable environments, such as food production. Designed to take both axial and radial loads in one direction simultaneously. Double row tapered roller bearings are another stronger bout of bearings which have the capacity to move axial and radial forces in two directions making it imperative for the machines with high turning torques.

The most common applications for tapered roller bearings:.

  1. Tapered roller bearings are found in gear boxes in vehicles, especially in heavier trucks, in lathe spindles etc. where the axial and radial forces combine together to run the machine.
  2. Roller bearings are used in the mining industry to aid lifting equipment.
  3. Taper roller bearings are also used in axle systems of machines and vehicles to ensure a good performance of the concerned machine.
  4. Vehicular and plant/machinery engines have parts that utilise taper roller bearings.
  5. The Aviation industry used taper roller bearings in aircraft and helicopter transmissions. They are also used in aircraft fuel pumps.

If you have any requirements for roller bearings, or need assistance on measuring a roller bearing to replace in a particular machine or vehicle, do not hesitate to contact hydra seals via our contact page, or pop in to our trade counter and we’ll assist in measuring and fitting a high quality replacement ball bearing or roller bearing.

Where are Industrial Seals Most Commonly used?

Top 8 Industries where Industrial Seals are most commonly used?

The main purpose of an industrial seal is to seal the opening between a static and rotating component. It is vital to use high performance seals for improving the efficiency of equipment. The following are 10 top industries which use hydraulic, pneumatic seals or a combination of both.

  1. Farm Machinery & Agricultural Plant

During agricultural harvesting seasons, agri-machinery needs to perform with optimal efficiency. Machinery used outdoors, such as ploughing equipment, tractors, harvesters etc, all face exposure to the weather elements, and with the Irish and UK climates consistent flooding, numerous storms and generally damp conditions, frequent contamination from the surroundings erode both hydraulic hose, hose fittings, bearings and other parts of the machiners. There is a constant need to repair and maintain farm equipment, the use of high performance seals, play an important role in productivity and lowering expenses. Farm implements use single acting hydraulic seals on harvesting, threshing, baling, drainage and on crop harvesting machinery.

  1. Amusement Machines

Amusment machines, such as roller costers and other attractions at funfares, including some of the rides at Tayto Park for example, would require hydraulic seals and other parts to keep running. Imagine how much would be lost if a major amusement ride broke down for a day. When the seal fails in the brake system, it can leak brake fluid, forcing a shutting down of the ride for repairs. Not to mention the cleanup afterwards.

  1. Auto Industry

Almost every vehicle assembly department uses pneumatic rams on assembly jigs. Engineers prefer pneumatics as they are quieter and cleaner, which can prevent any leakage from contaminating its surroundings. Sound absorbing materials such as polyurethane and rubber are effective in achieving significant compressed air savings.

  1. Cheese Manufacturers

Ireland has a long tradition for quality farming, and cheese making in itself is a niche of the agri-industry. There is also a trend to consume more homegrown / organic grubsteaks, and apart from the major dairys of the Mitchelstown Cheese Factory (Dairygold), there is a plethora of small businesses manufacturing in the niche, This machinery generally uses Pneumatic seals, spring energized seals, wipers and guide rings are used on manufacturing and packaging machines in the cheese industry.

  1. Coal Mining Equipment

Coal mining is still carried out in various parts of the world, and hydraulics are used extensively in the underground mining machinery, while pneumatics are used on roof support machinery. Essential to the mining industry is safety and the use of high performance parts to provide extraordinary service life so that downtime and maintenance is kept to a minimum.

  1. Concrete Pumping

Concrete pump designers face many challenges because concrete is heavy, viscous, abrasive, contains pieces of hard rock and solidifies if not kept moving. One of the causes of dangerous blockages can be attributed to improper setting up of the pump system, and requires specialised sealing and proper guide element replacement when the seals are replaced.

  1. Earth-Movers & Excavators

High performance oil seals and hydraulic seal kits are required for heavy earthmoving, excavators, dozers and backhoe loaders. The mining and construction industry is the heaviest user of high performance seals and reliable wiper seals.

8 Printers

Some may say printing is a dying trade, but with Newspapers and Printed books still in demand, and 4% of marketing budgets being pumped into traditional printed marketing, such as flyers and business cards, the demands of the fast-paced publishing industry benefits immensely from machine parts manufactured with high performance polyurethanes and rubber materials to allow for greater speeds and higher productivity.

4 different types of hydraulic seals- hydra seals hose and bearings

4 Different Types of Hydraulic Seals

The Main Types of Hydraulic Seals

There are several types of Hydraulic Seals, which are available as Rod Seals, Piston Seals and Wiper Seals. Before you purchase a seal for whatever application you are using, there are a few requirements that need to be checked considered;
• Diameter of Inner Shaft
• Diameter of Outer Shaft
• The Radial Cross Section
• The Operation Speed
• Pressure and Temperature Placed Upon Seals in Operation
• Vacuum Rating
Types of Seals:
Piston Seals are used in hydraulic cylinders, and prevent fluid from flowing over the cylinder head by sealing against the cylinder bore. This application, the sealing lip is in contact with the housing bore and the seal is pressed within the shaft. Rod Seals are also used for preventing fluid from leaking. They are placed external to the cylinder bore. They would be considered a radial seal, and prevent fluid from leaking from within the cylinder to the outside. Symmetric Seals work equal or symmetric to piston/rod seals and Axial Seals make contact with or are “in-axis” with the housing components. There are two variations of Hydraulic Seals, one would be dynamic seals and the other is an Exclusion Seals.
Dynamic Seals prevent contamination to fluids by creating a void between moving and non-moving parts. These types of seals would be typically piston seals. Exclusion seals help keep debris from machine bearings and moving parts. Typical types of exclusion seals would be wiper seals, which wipe the debris away. There are also V seals and scraper seals within the exclusion seal range.
