Single/Double Lip Oil Seal NBR PTFE Teflon Shaft Seals

Material advantages: polytetrafluoroethylene (PTFE) also known as Teflon or plastic king (F4), is a copolymer of tetrafluoroethylene monomer.

Wear reduction: the friction coefficient of PTFE is only 0.02, which is 1/40 of rubber.
Self-lubricity: PTFE surface has outstanding self-lubricity, almost all viscous substances can not adhere to its surface.

Product advantages:
PTFE oil seal has the following advantages compared with rubber oil seal:
Rubber oil seal with spring pressed lip mouth, and the shaft contact surface width is only 0.3-0.5mm, PTFE oil seal with no spring wide lip dynamic structure, and the shaft contact surface width of 5-7mm, so that you can maintain a sufficient oil film, and the shaft eccentric is not sensitive, in the radial runout of 0.4mm working conditions can still work normally.
