Rod U-cup seal 45 x 60 x 10 DR75 AU, PN 029275
Code: SKL_M137030
Product detailed description
The U-cup seal according to PN 02 9275 is designed for sealing rods in hydraulic equipment. The sealing function in the pressureless state is ensured by the radial preload of the seal (compression of the lips after fitting into the groove), during operation the pressure of the working fluid presses the lips against the sealing surface. Polyurethane AU has high mechanical strength and wear resistance.
Technical parameters: material AU 80 or AU 90 (polyurethane), colour black, pressure load max. 16 MPa (AU 80) or 32 MPa (AU 90), temperature range −30 °C to +80 °C, sliding speed up to 0.5 m/s, radial clearance max. 0.20 mm. Media: mineral hydraulic oils, engine and gear oils, lubricating greases, air. Polyurethane is not resistant to steam, alkalis, acids and amines.
Installation space: rod diameter d 45 mm, groove bottom diameter D 60 mm (+0,15), seal height h 10 mm, groove width b 10.6 mm (±0,1). Rod guidance with fit H8/e9. Can be fitted in split and non-split grooves.
Installation: clean the installation space, lightly lubricate the U-cup seal, do not pull it over sharp edges and threads (lead-in angles 15–30°, rounded transitions), roughness of moving surfaces max. Ra 0.4 µm. After inserting the seal into the groove, wait approx. 120 minutes for the deformation to recover. A replacement with higher load capacity (40 MPa) is the MA 30 seal made of AU 95.
Dimensions: 45x60x10, 45-60-10, 45/60/10, 45 x 60 x 10 mm.
