Rotating shaft seal OAB

double lipVstainless steel

VR radial sealing rings seal rotating shafts, spindles, journals and all rotating axes. The main advantage of the VR radial shaft sealing ring is the low torque on the rotating element to be sealed. The torque is reduced by 50% to 60% compared to conventional lip seals. This benefit allows: The use of standard or stainless steel shafts Removal of surface treatments: carburizing, hard chrome plating, etc… The direction of rotation is irrelevant High non concentricity (up to 0.4mm) Roughness Ra 0,4 ED This allows: A very low friction on the shaft Very low heat build-up Use with many fluids (8 different standard elastomers) Reduced space requirement How it works: The operation of the VR joints is based on 2 fundamental characteristics: A radial force between the seal lip and the shaft Additional pre-tension of the lips on the axis
