Depending on the application, it is listed for the front, rear or rear-center position.
- Heat-Treated Stainless Steel: The sleeve is highly durable and resists environmental factors such as corrosion.
- Enhanced Sealing: Gives the seal an improved surface to help prevent leaks and maintain the integrity of the assembly.
- Efficient Installation: No shaft removal or machining is required, so installation is quick and helps save time and labor costs.
- Cost-Effective Repair: Designed to increase shaft life and help prevent further wear by forming a protective barrier. This helps minimize downtime and the expense of more invasive repairs or replacements.
Specifications: The width on the shaft is 14.3 mm (0.563 in). Country of origin: Taiwan. The quantity needed varies by application.
Signs a repair sleeve may be needed include a leak that returns at a shaft seal, or a visible groove worn into the shaft where the old seal lip rode. If a worn shaft surface is the cause, this sleeve covers it with a fresh sealing surface.
