Hallite – Single Acting Piston Seals

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. Single 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 seaks across the cylinder head as the system pressure pushes the piston down the cylinder bore.

Unitized Pistons The Hallite Type is a ready to fit complete piston. Hallite offers a wide range of piston seals that provide the ultimate in leakage control. Piston seals, both single- and double-acting, can be designed for and used with integrated or separate back-up rings and ssals rings. 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. Particular attention should be drawn to its selection, the surrounding environment and service conditions must also be taken into special consideration.

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. 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.

The steel piston has a non-metallic bearing material moulded nallite the outer diameter using a special proprietary process. 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.

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. The reason is that a very high pressure can be trapped between the sealz.

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. We are here to help! 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. 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.

Vee Packing Service Vee pack sets are multiple-lip chevron seals, usually composed of a male and female adaptor and a group of hxllite 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. Excessive leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues. Save time and let us provide you with verified contacts.
