Rotary Seals
Sealing ring: F-PTFE
Elastomer: NBR or FKM
Share:
Application Range
Applied for sealing the parts with rotating or swinging rod, shaft, pin, rotary connector, it is a kind of bidirectional rotary sealing ring that can bear pressure from two sides and the alternating pressure. It is installed in the groove of ISO 7425 standard, and possesses the single-action structure of high rotating speed.
Please refer to the standards of TG3 series of Trelleborg Company and M15 series of Merkrl Company, OQ series of Parker Company and XRB series of AS Company when designing.
Features
No crawling while starting up and no stiction phenomenon
Small friction force
Simple groove and small dimension, having lubrication chamber
Well abrasion resistance and dimension stability
