INA Sealing Rings

Sealing rings of series G, GR and SD are matched to the small radial dimensions of INA drawn cup needle roller bearings with open ends and with closed end and of needle roller bearings without an inner ring. These contact seals protect the sealed area against contamination, spray water and the excessive loss of grease. In comparison with spring-preloaded rotary shaft seals, they have significantly smaller cross-sectional dimensions, lower friction values and allow space-saving, economical sealing of shafts undergoing rotary and axial motion. The sealing rings are easy to fit, since they can simply be pressed into the housing bore. In rotary motion, sealing rings allow high circumferential speeds at the seal lip, depending on the surface quality of the shaft. Additional Information: Item Code: INASEALINGRINGS
