SHAFT SEALS FOR RECIPROCATING MOTION

DC4

Description

The DC4 profile is a shaft seal composed of a single metal cage with a rubber coating and a double sealing lip suitable for linear movements, the fluids being separated by the integrated springs. * Very good static sealing * Very good thermal expansion compensation * Greater roughness is allowed in the housing * Reduced risk of corrosion * Sealing for low and high viscosity fluids * Modern sealing lips with low radial forces * Sealing lips designed for linear movements * Fluid separation system

Application

All types of linear applications Shock absorbers Power-assisted steering
