Hydraulic seals

Hydraulic cylinder systems are sealed using a complex configuration of high-performance hydraulic seals, and we at Hallite offer a wide range of seals for applications within these cylinder systems:

Mining industry heavy equipment image for hydraulic seals and bearings
Find hydraulic rod seals

Rod seals

The rod seal is the most critical hydraulic seal on any type of fluid power equipment. They prevent leakage from within the cylinder to the outside which can reduce equipment performance, and in extreme cases can cause environmental issues.

Find single acting piston seals

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

Find double acting piston seals

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 piston as the system pressure pushes the piston down the cylinder bore.

Find vee pack seals

Vee packs

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.

Find wiper seals

Wipers

Wipers are installed in hydraulic cylinders to prevent contaminants from entering the cylinder, which is one of the primary causes of premature hydraulic seal and component failure.

Find bearings

Bearings

Hallite offer bearings in many materials all of which offer high wear-resistance and demonstrate excellent friction properties. The Bearing or wear ring guides the piston and piston rod of a hydraulic cylinder.

Find unitized pistons

Unitized pistons

An accepted solution for Construction, Off Highway and Agricultural cylinders, unitised pistons provide OEM customers with extended service life whilst reducing manufacturing and assembly costs.

Find swivel 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.

Find rod buffer seals

Rod buffer seals

The buffer seal protects the main rod seal from the effects of shock pressure loading. The buffer seal needs to allow adequate lubrication of the main seal and not cause a pressure trap between itself and the main seal.

Find pneumatic seals

Pneumatic seals

Hallite's Pneumatic Seals may be used for rotary and reciprocating motions. Since the launch of the versatile 600 series, there has been a continual research and development program, by Hallite and OEMs.
