Motorcycle oil seal 20×34×7 mm

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.

1. Superior Sealing Performance: The 20×34×7 mm oil seal creates an airtight and oil-tight barrier, effectively preventing lubricant leakage and blocking the ingress of dust, dirt, and moisture, which is vital for protecting internal components from wear and corrosion.

2. Exceptional Durability: Manufactured from premium oil-resistant rubber (e.g., NBR), it resists degradation from motorcycle oils, fuels, and high operating temperatures, ensuring a long service life even under harsh riding conditions.

3. Precision Fit and Compatibility: With strict adherence to dimensional standards (20mm ID, 34mm OD, 7mm thickness), it offers a perfect fit for shafts and housings in compatible motorcycle models, eliminating the need for modifications during installation.

4. Enhanced System Reliability: By maintaining proper lubrication levels and preventing contamination, this oil seal contributes to the smooth operation of motorcycle engines and transmissions, reducing the risk of component failure and ensuring a dependable riding experience.

1. Motorcycle Transmission Systems: Ideal for sealing countershafts, gearbox shafts, and other rotating components in motorcycle transmissions, such as those in CG125 and similar models, to prevent gear oil leakage.

2. Engine Component Sealing: Suitable for sealing auxiliary shafts, balance shafts, or other engine-related shafts in motorcycles, ensuring engine oil remains contained and contaminants are kept out.

3. Aftermarket Maintenance and Repair: A go-to replacement part for motorcycle repair shops and DIY enthusiasts when servicing or rebuilding motorcycle powertrain components, ensuring restored sealing integrity.

4. OEM Replacement in Manufacturing: Used by motorcycle manufacturers or assemblers as a standard sealing component for new motorcycles or engine/transmission assemblies that require the 20×34×7 mm size specification.
