Single acting NBR piston seal with rubberised fabric reinforcement & full width POM bearing ring.

Design

CLARON STYLE PW.../L is a precision moulded Nitrile rubber with a fabric reinforced base. Produced with initial radial interference to effect low-pressure sealing, the seal is progressively energised at higher pressures thereby increasing the sealing force. Rubberised fabric has the advantage of retaining the sealing media within it's surface, thus reducing friction and wear. The full width polyacetal bearing ring resists extrusion of the seal to allow greater clearances and higher pressures, and provides bearing support for the piston preventing misalignment and metal to metal contact between piston and bore.
