CRS1
The CRS1 (fig 1), CRSH1 (fig 2), CRSA1 (fig 3) and CRSHA1 (fig 4) seals are designed with a metal case and a conventional spring-loaded sealing lip. Some of them have a sealant on the outside diameter to compensate for imperfections in the housing bore.







CRS1: Seal with a single steel case, a conventional sealing lip and a carbon steel garter spring.
CRSA1: Seal with a single steel case, a conventional sealing lip, a carbon steel garter spring and an auxiliary, contacting lip.
CRSH1: Seal with a double steel case, a conventional sealing lip and a carbon steel garter spring.
CRSHA1: Seal with a double steel case, a conventional sealing lip, a carbon steel garter spring and an auxiliary, contacting lip.
CRS seals are available with sealing lips made of nitrile rubber for general-purpose applications and of fluoro rubber, providing improved high temperature and chemical resistance.
The permissible operating conditions are provided in the Seal selection table.
