Double-lip oil seal for worn shafts
Double-lip oil seal for use on worn or grooved shafts or increased runout.
Optimized seal lip design contacts the shaft at a new contact point which enables this seal to be fitted on most grooved shafts where a repair sleeve or a new shaft would be required. For increased runout or eccentricity, the seal lip length is optimized. Thermoplastic reinforcement element ensures concentric fitment and increased corrosion resistance. 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. Available in a wide range of elastomers and small quantities for repairs and seal replacement and can be shipped in 1 to 3 days.
