Split, double-lip oil seal

Split double-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.  The secondary lip serves as both effective protection against airside contaminants and as a lube retainer.  Maximum service life can be achieved by applying a suitable lubricant between the two sealing lips.  Seal is split for easy on-site installation with a minimum of equipment dismantling.  Normally, R10 is used for original equipment build and R10S 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
