This motorcycle oil seal, sized 20×34×7 mm, is a critical element for maintaining the integrity of motorcycle mechanical systems. Constructed from high-quality nitrile rubber (NBR) or equivalent oil-resistant materials, it features a robust design with precise dimensional accuracy. The seal’s inner diameter (20mm) fits snugly around shafts, while the outer diameter (34mm) secures into housing bores, and the 7mm thickness provides sufficient structural stability. It is engineered to withstand the dynamic stresses, temperature fluctuations, and chemical exposure within motorcycle engines and transmissions, delivering consistent sealing performance over extended periods. Whether for OEM replacement or aftermarket maintenance, this seal meets the stringent requirements of motorcycle applications, ensuring optimal functionality and reduced maintenance costs.
Creates an airtight and oil-tight barrier, effectively preventing lubricant leakage and blocking the ingress of dust, dirt, and moisture to protect internal components from wear and corrosion.
Manufactured from premium oil-resistant rubber (e.g., NBR), resisting degradation from motorcycle oils, fuels, and high operating temperatures for extended service life under harsh riding conditions.
Adheres strictly to dimensional standards (20mm ID, 34mm OD, 7mm thickness) for a perfect fit on compatible motorcycle shafts and housings, eliminating installation modifications.
Maintains proper lubrication levels and prevents contamination, contributing to the smooth operation of engines and transmissions while reducing component failure risks.
Ideal for sealing countershafts, gearbox shafts, and rotating components in motorcycle transmissions (e.g., CG125 and similar models) to prevent gear oil leakage.
Suitable for sealing auxiliary shafts, balance shafts, or other engine-related shafts in motorcycles, ensuring oil containment and keeping contaminants out.
A go-to replacement part for motorcycle repair shops and DIY enthusiasts when servicing or rebuilding powertrain components to restore sealing integrity.
Used by motorcycle manufacturers or assemblers as standard sealing components for new builds requiring the 20×34×7 mm specification.
