Single Lip PTFE Stainless Steel Oil Seals

Product Description

The PTFE lip seal is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. Since the lip is not spring energized, the radial lip contact forces are lower than a rotary lip seal, which allows the seal to function at much higher surface speeds (up to 30m/s). 

PTFE seal lip is pulled into a trumpet shape during processing. Since the PTFE has a memory contraction ability after being drawn, the friction heat generated in the work will make the lip shrink continuously, so it does not need the help of a spring and it will hold tightly. On the shaft, there is no gap between it and the shaft surface, and wear can be compensated.
