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.
Manufactured from premium oil-resistant rubber (NBR) that resists degradation from motorcycle oils, fuels, and high operating temperatures, ensuring a long service life.
Strict adherence to dimensional standards (20mm ID, 34mm OD, 7mm thickness) provides a perfect fit for compatible motorcycle models without needing modification.
By maintaining proper lubrication and preventing contamination, it contributes to the smooth operation of engines and transmissions, reducing component failure risk.
Ideal for sealing countershafts, gearbox shafts, and other rotating components in transmissions (such as CG125 models) to prevent oil leakage.
Suitable for sealing auxiliary shafts, balance shafts, or other engine-related shafts, keeping engine oil contained and dirt locked out.
A reliable replacement part for repair shops and DIY mechanics when rebuilding powertrain components to restore factory-grade sealing.
Used by motorcycle manufacturers and assemblers as a standard component for new engines or transmission builds requiring the 20×34×7 mm specification.
