Spring-loaded single-lip oil seal-R1

R1


Spring-loaded single-lip oil seal

Spring-loaded single-lip rotary shaft seal with non-metallic reinforcing element.

Used for oil and grease retention.

The optimized seal lip design uses a stainless steel garter spring to maintain a constant radial lip load, thus ensuring optimum sealability.  The non-metal reinforcement element ensures concentric fitment and increased corrosion resistance over traditional shaft seals.  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.  Can be provided for larger and non-standard bore tolerances.  For dirty, dusty or polluted environments, our R2 style with additional dust lip should be used.
