Product Description
The 141113/1 (also documented as 141113-1) is a specialized oil and grease seal featuring a triple-dimension profile: 47.12mm (Outer Diameter) x 30.23mm (Inner Diameter) x 7mm (Width). This seal is engineered to fit the precision tolerances of the Royal Enfield rear wheel hub, specifically where the distance collar meets the bearing.
Manufactured from high-nitrile rubber (NBR) with a reinforced internal steel spring, this seal maintains a tight grip on the axle collar even during high-speed rotation and intense heat. If you notice grease leaking onto your rear spokes or if you hear a “grinding” noise from the rear wheel, it is often a sign that this seal has failed, allowing contaminants to destroy the hub bearings.
Key Features:
-
Triple-Lip Sealing: Designed to keep grease in and external contaminants out under high-pressure conditions.
-
Reinforced Steel Spring: Features an internal garter spring that ensures a constant 360° seal against the rotating collar.
-
High-Heat Resistance: Made from specialized compounds that won’t harden or crack despite the friction heat generated in the hub.
-
Precision OE Dimensions: Exact 47.12 x 30.23 x 7mm fitment, ensuring no gap for moisture ingress.
-
Wide Compatibility: A “universal” part across most 350cc and 500cc platforms from 1955 to the late UCE era.
