Rotation seals of the HV 280 series have been in use for years in machine construc- tion as elastomeric seals for shafts and bear- ings. They effectively and reliably provide sealing against attack by dust, dirt, oil and water splashes etc for axial sealing areas. Design Variations: V-rings are available in four design variations: VA: Standard profile with vertical backside. Large range of sizes (3 mm up to 2020 mm) shaft diameter. VS : Wider body, designed to take higher ra- dial force than the design VA. Available for shaft diameters from 5 mm up to 310 mm. VL : Special profile for small mounting spaces. Available for 135 mm up to 165 mm shaft diameters. VE : For heavy duty application and large di- ameter. Normal commercial tightening strap can be used to improve axial fit. Special Features: Reliable and convenient axial sealing No wear (erosion) of shaft Safe function even for slightly tilled oppo- site (running) face or low shaft eccentricity Simple slide assembly in small mounting space Lower storage costs because of suitability to various shaft diameters Increases life of machine components due to protection of bearings Lower starting torque and friction in opera- tion No sticking at the sealing lip even after long periods of stand stills. Highly wear resistant of elastomer material Also available in FPM 288 Material Velocity Temperature : Rubber elastomer : peripheral velocity (rotary) to 8 m/s : -60 up to +220 °C (depending on the material) VA, VS, VL and VE V-ring
