BECA 151 - 153 - 155

Hydraulic seals / Rod seals

Description

The BECA 151 - 153 - 155 profiles are double acting composite rod seals composed of a filled PTFE friction ring and pre-tightened rubber O'Ring. They can be assembled in grooves according to standard ISO 7425/2. Option of connecting the seal to 1 or 2 back-up rings.

Advantages

Optimal sealing in static and dynamic applications
Low friction coefficient; no stick-slip effect
Excellent abrasion and extrusion resistance
Wide temperature range and excellent chemical resistance, depending on the material selected for the O'Ring
