Counter Surfaces - Maximize the Lifetime of Hydraulic Systems

Counter Surfaces

Maximize the lifetime of your hydraulic systems now

A new approach is required for the definition of counter surfaces to ensure effective sealing in dynamic applications where chrome plating is replaced by alternative coatings.

Traditionally piston rods in hydraulic systems were chrome plated to provide friction and surface finish characteristics. Under the REACH directive, Hexavalent Chromium (CR6) is a substance of high concern and must now be omitted from any hydraulic application, leading to the adoption of alternative coatings for the hydraulic system’s piston rods. 

To maximize the performance and system life in hydraulic systems, these should be designed to optimize a system’s tribology, which is dependent on the interaction of a system’s seals, hydraulic fluid and the finish of the mating surfaces.

The lubrication within the hydraulic system is fundamentally affected by the surface finish of the mating surfaces. Their characteristics will determine the lubrication within the system and therefore the tribological environment.

An Introduction to Lubrication Management
(Language: English)

This white paper is designed to be a useful overview of lubrication management through the lens of sealing solutions. It draws on the expertise both within Trelleborg Sealing Solutions and in the wider industry to provide a ‘jumping-off point’ in tribology. A point at which you can deal in the world of sealing and lubrication with a greater knowledge and grounding – from its history and development to the latest solutions and approaches.
