Shock Absorber Piston

Slope 0.09 low friction force Shock Piston PTFE Band on OD Applied In Truck Shocks Poly Fluoro Piston Bands are designed for hydraulic and pneumatic equipment. Its unique design prevents equipment seizures which can arise with other forms of guidance materials. Poly Fluoro Piston Bands offer extremely low friction and break-away forces. This material is also resistant to all hydraulic fluids, and is suitable for temperatures up to 200°C. Poly Fluoro Piston bands are the

32 # PTFE banded shock absorber piston with HRB60 - 90 density 6.5g/cm3 used in Car The bearing material is made from PTFE with a 40% Bronze filling and is specifically designed to support heavy loads. The exceptional physical properties and PTFE lubricants make the piston bands suitable for use on rams or pistons in reciprocating applications. Meanwhile,we can also add other fillers with PTFE,such as glass fiber,carbon fiber,graphite and so on. Specifications: Physical
