R9S


Split, single-lip oil seal

Split single-lip oil seal with a solid rubber construction

The optimized seal lip design uses a garter spring to maintain a constant radial lip load, thus ensuring optimum sealability.  Seal is split for easy on-site installation with a minimum of equipment dismantling.  Normally, R9 is used for original equipment build and R9S for onsite replacement.

This style is available in a wide range of elastomers and small quantities for repairs and seal replacement and can be shipped in 1 to 3 days.  For dirty, dusty or polluted environments, our R9S style with additional dust lip should be used.
