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, 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 100% PTFE Filled PTFE Filler Type Inorganic filler Glass fiber, Graphite, Bronze, Carbon fiber, MoS2 Organic filler Polyimide, Aromatic Polyester, Polypheylene Sulfide       Depending on applications, PTFE can be mixed with fillers to meet the requirements of application in order to provide the optimum sealing properties. Features:Excellent resistance to corrosion and chemical productsWide temperature using range (up to 250℃)Low coefficient of frictionSelf lubricationImproved wear resistance
