Nitrile Single Lip Sealing Rings: Designed as contact seals, these sealing rings protect the bearing position against contamination, spray water and the excessive loss of grease. Sealing rings are matched to the small radial dimensions of needle roller bearings. They are very easy to fit, as they are simply pressed into the housing bore. Sealing rings allow circumferential speeds at the seal lip of up to 10 m/s depending on the surface quality of the shaft. This sealing ring is made from synthetic NBR elastomer (coloured green). They are suitable for shaft diameters from 8mm to 80mm and have a rubber-encased steel reinforcement for stiffening purposes with a wave-shaped rubber profile. This provides good sealing on the outside diameter and reduces the forces required for fitting. Suitable for operating temperatures from -30 to +110 deg C.
Benefits: Improved sealing on the outside diameter, reduced force required for fitting.
