PTFE Wear Rings
This PTFE wear ring is used in hydraulic and pneumatic cylinders to prevent metal contact between movable parts.It has good compressing strength,Website:, excellent hardness, heat distortion and good self-lubrication abrasion. The wear ring is used with U-seal to bear larger pressure.
Type:Single turn(scarf cut),multi-turn(spiral cut)and solid(uncut).
Technical data:
Velocity: ≤15m/sTemperature:-60 ℃~+200 ℃Surface supporting pressure:15N/mm2
Material range:Include virgin& all filled grades PTFE and others from Dupont, Daikin, 3M, 3F, etc.
Virgin PTFE
