Special Features: Hydraulic seals made by Polyurethane for piston/rod seals types such as UN to SI/LA and the associated types have been used for years in light and intermediate duty hydraulic applications because they provide very good sealing exchange and significantly longer life compared to NBR materials. Highly wear resistant modified Polyuret- hane mixture Quick and assured response event at lo- wer temperature due to the special profile and design Simple to assembly in closed grooves Better extrusion resistance compared to NBR Larger extrusion gap is therefore pos- sible Small mounting space Cost effective Extensive range of sizes are available UN, RSA, SI, SI/L and SI/LA 102 Material Operational pressure Velocity Temperature : Polyurethan : UN, SI and SI/L up to 40 MPa (400 bar) SI/LA up to 50 MPa (500 bar) : reciprocating to 0,8 m/s : -40 up to +110 °C Rod Seal
