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. Double Acting Piston Seals. Particular attention should be drawn to its selection, the surrounding environment and service conditions must also be taken into special consideration. For a cylinder which is halllite 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.

Ram Seal for concrete pump.

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. Please enter Mobile Number.

An accepted solution for Construction, Off Highway and Agricultural cylinders, the Unitized Piston provides the OEM customer with proven extended service life whilst significantly reducing manufacturing and assembly costs.

We are here to help! The reason is that a very high pressure can be trapped between the seals. Unitized Pistons The Hallite Type is a ready to fit complete piston.

Small amounts of leakage on the rod are cosmetically unattractive, and in many applications are becoming increasingly unacceptable. 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. These include a unique profiled NBR pkston polyurethane PU seal, and a specifically designed three halite seal for the mining industry comprising of an O-ring energiser, PU shell and a polyacetal anti-extrusion ring.


The wiper seal is the most undervalued seal type in the hydraulic cylinder in relation to its important function.

Piston seals, both single- and double-acting, can be designed for and used with integrated or separate back-up rings and guide rings.

Please enter your Email ID. 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.

Compare Quotations and seal the deal. 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. Swivel Seals Swivel seals are designed for slow rotary applications, such as the hydraulic swivels, which allow the transmission of pressurised hxllite between the chassis and body of mobile hydraulic equipment.

HalliteĀ® seals easy to order at

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. Tell us what you need by filling in the form. The steel piston has a non-metallic bearing material moulded over the outer diameter using a special proprietary process.

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. Please enter full name.

Receive Verified supplier details. The T, which is a woven fabric reinforced polyester resin bearing is available in three forms, cut sals, spiral lengths and flat coils, and is compatible with a wide range of fluids, and is used extensively in mining applications. Double Acting Piston Seals Piston Seals or Piston Rings are used psiton 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.


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.

Hallite offer bearings in various types of materials all of which offer high wear-resistance and demonstrate excellent friction gallite. Please enter your name. 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. Save time and let us provide you with verified contacts. Company Factsheet Nature of Business Retailer. 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.

I agree to the terms and privacy policy. Single Acting Piston Seals Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to pisto that pressurised fluid does halliet leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.

Hallite Single Acting Piston Seals

Excessive leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental seeals. Hallite offers a wide range of hydraulic rod seals for both single-acting and double-acting systems.

Hallite offers a wide range of piston seals that provide the ultimate in leakage control. Particular attention should be paid to pair the rod seal and the wiper for the best sealing performance.
