Small amounts of leakage on the rod are cosmetically unattractive, and in many applications are becoming increasingly unacceptable. Excessive leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues.

Hallite – Double Acting Piston Seals
Please enter Mobile Number. Hallite offer bearings in various types of materials all of which pistob high wear-resistance and demonstrate excellent friction properties. For a cylinder which is exclusively single-acting, capable of sealing dynamic pressure from one side unidirectionalit is always best to choose the type of seal designed to provide optimum sealing qualities for single-acting functions.
Double Acting Piston Seals. Hallite offers a wide range of hydraulic rod seals for both single-acting and double-acting systems. Produced today in a wide range of sizes, bearing and seal materials, Hallite’s exclusive Unitized Piston is available off the shelf in numerous standard metric and inch sizes. These include a unique profiled NBR energised polyurethane PU seal, and a specifically selas three element seal for the mining industry comprising of an O-ring energiser, PU shell and a polyacetal anti-extrusion ring.
The reason is that a very high pressure can be trapped between the seals. Swivel Seals Swivel seals are designed for slow rotary applications, such as the hydraulic swivels, which allow the transmission of pressurised services between the chassis and body of mobile hydraulic equipment.
Single Acting Piston Seals Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and pistno designed to ensure that pressurised fluid does not leak across the cylinder hallute as the system pressure pushes the piston down pison cylinder bore.
At the same time, it prevents any metal-to-metal contact, which will damage and score the surfaces and eventually cause seal damage, leakage and component damage.
Hallite Single Acting Piston Seals
Piston seals, both single- and double-acting, can be designed for and used with integrated or separate back-up rings and guide rings. Bearings The function of the Bearing or wear ring is to guide the piston and piston rod of a hydraulic cylinder, as well as to withstand arising side loads.
The best sealing capacity of a double-acting cylinder, capable of sealing dynamic pressure from both sides bidirectionalis achieved by choosing a double-acting seal.
Vee Packing Service Vee pack sets are multiple-lip chevron seals, usually composed of a male and female adaptor and a group of three or five vee rings, are popular for sealing rods and pistons in medium to heavy duty applications and are compatible with both single and double acting cylinders. Wipers Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
Please enter your name. Originally designed and patented by Hallite Seals over 25 years ago, the Unitized Piston continues to establish and develop itself as a unique solution for our customers many and varied applications. Universal Products Seals Private Limited. Hallite offers a wide range of piston seals that provide the ultimate in leakage control.
We are here to help! Double Acting Piston Seals Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurised fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore. Ram Seal for concrete pump. A glass filled nylon wear ring T offers high bearing load capacity over a broad range of temperatures, whilst our high strength nylon bearing T is suitable for telescopic applications.

The wiper seal is the most undervalued seal type in the hydraulic cylinder in relation to its important function. Our T63 polyacetal wear ring is suitable for both fluid and pneumatic cylinder applications, the T87bronze filled PTFE bearing is suitable for higher temperature applications.
It is then finish machined to provide a tight tolerance with the bore of the tube and also for the installation of the chosen seal. If a less aggressive rod seal is paired with an aggressive wiper, the wiper can scrape off the microscopically thin film of oil that remains on the rod in microscopic surface imperfections during the return stroke, resulting in system leakage.
Save time and let us provide you with verified contacts. A piston design where two single-acting seals on the piston for a double-acting cylinder are used can easily give rise to a breakdown. The choice of piston seal is decided by the way in which the cylinder operates.

Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system. Please enter your Email ID. Unitized Pistons The Hallite Type is a ready to fit complete piston.
