help SKF CRW1 FAQ
What does the SKF CRW1 designation describe?
CRW1 identifies a radial shaft seal with a single steel case, an SKF Wave sealing lip, and a carbon-steel garter spring. It is used between rotating shafts and stationary housings.
What is special about the CRW1's SKF Wave lip?
The lip follows a wave-shaped path rather than contacting the shaft along one narrow line. SKF says this increases pumping action while spreading heat and wear over a larger contact area.
Does a CRW1 have a separate dust lip?
A standard CRW1 does not have the auxiliary lip used for additional contaminant exclusion. Buyers needing that feature should examine the related CRWA1 design.
What materials are available for SKF CRW1 sealing lips?
Common catalog versions use nitrile rubber or SKF Duralife fluoro rubber. The correct suffix and material depend on the lubricant, shaft speed, and operating-temperature range.
