The 100X135X12CRWA1R is a radial shaft seal from SKF, a trusted manufacturer and industry leader. CRWA1 types are low-friction seals with a metal outside diameter, a nitrile rubber SKF WAVE sealing lip design, a carbon steel garter spring, and a non-contacting auxiliary lip. The metal outside ensures easy installation while maintaining a firm, accurate bore fit. SKF WAVE lips are designed to reduce friction and heat generation while pumping lubrication back into the bearing and expelling contaminants. At Quality Bearings Online, we offer a comprehensive range of high quality and reliable low-friction radial shaft seals, including the SKF CRW1, CRWA1, and CRWH1 lines. These seals are expertly designed to retain lubrication, but they can also be used to protect against contaminants due to their non-contacting auxiliary lip. Extensive experience, research, and material development by SKF have produced the robust nitrile rubber with resistance to aging, excellent pumping ability, and wear resistance. The dimensions of this 100X135X12CRWA1R seal are 100x135x12mm.

Key Features

SKF WAVE Lip Design

SKF WAVE seals signify a hugely important development in the design of radial shaft seals. They are made using a special mould form which gives the seals hydrodynamic properties. WAVE seals are able to reduce friction between the shaft and lip (up to 20% reduction compared to standard lips) and therefore reduce heat generation at the point of contact. This design also generates a higher pumping rate, pumping lubrication back into the bearing and expelling contaminants.

Protection Against Contamination

With a carbon steel garter spring providing improved sealing against the shaft and an additional auxiliary dust lip facing outwards, the 100X135X12CRWA1R is ideally constructed to exclude contaminants from entering while retaining grease or oil inside the assembly.
