CRW1 CRWA1 CRWH1 and CRWHA1 radial shaft seals
The seals are primarily designed to retain lubricants but are also suitable for contaminant exclusion, especially the CRWA1 and CRWHA1 seals designed with an auxiliary lip.
CRW1: Seal with a single steel case, SKF WAVE lip and a carbon steel garter spring.
CRWH1: Seal with a double steel case, SKF WAVE lip and a carbon steel garter spring.
CRWA1: Seal with a single steel case, SKF WAVE lip, a carbon steel garter spring and an auxiliary, non-contacting lip.
CRWHA1: Seal with a double steel case, SKF WAVE lip, a carbon steel garter spring and an auxiliary, non-contacting lip.
All of these seals are available with sealing lips made of either nitrile rubber or the SKF developed fluoro rubber compound SKF Duralife. Other materials are also available on request.
They optionally feature SKF Bore Tite Coating on the outside diameter, a non-hardening, water-based acrylic sealant that helps fill small imperfections in the housing bore.
