O-Rings

O-Rings offer an efficient and economical sealing element for a wide range of static or dynamic applications and can be used to seal practically all liquid and gaseous media.

Rod Seals

Trelleborg Rod seals are used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside.

Piston Seals

Trelleborg Piston seals are used in hydraulic cylinders for fluid sealing. They are internal to the hydraulic cylinder and seal against the cylinder bore, preventing fluid from flowing across the piston. This allows pressure build-up on one side of the piston.

Static Seals

In a static sealing application there is no movement between sealing surfaces or between the seal surface and its mating surface. The most common seal used in static sealing situations is the Trelleborg O-Ring.

Quad Ring

Quad-Ring® are four-lipped seals with a specially developed sealing profile which can be used in static & dynamic applications.

Rotary_Seals

Trelleborg Rotary seals are used in components with oscillating or rotating parts to keep lubricating fluids in while preventing ingress of mud and water. Trelleborg seals help improve components’ life and long term performance.

Back-up Rings

A Back-up Ring holds an elastomeric seal to its designed shape and in its correct place. Back-up Rings are commonly used with O-rings.

Guide Products

Guide Products are precision-engineered components designed to guide moving parts within hydraulic and pneumatic systems, preventing metal-to-metal contact. They ensure proper alignment, reduce wear, and enhance the overall performance and lifespan of cylinders.
