The Timken Company 99650 Redi Sleeve Shaft Repair Sleeve

Description:

The Timken 99650 is a Redi-Sleeve shaft repair sleeve, not an oil seal. It is designed to restore worn, grooved, or damaged shaft sealing surfaces without requiring costly shaft replacement or machining. Manufactured from precision-ground stainless steel, the Redi-Sleeve provides a smooth, wear-resistant sealing surface that extends shaft life and improves the performance of radial shaft seals. It is widely used in pumps, gearboxes, electric motors, compressors, industrial fans, conveyors, agricultural equipment, and heavy-duty rotating machinery. Maintenance teams, OEMs, and system integrators specify the Timken 99650 for equipment repair, retrofit projects, replacement, and preventive maintenance to restore sealing integrity, eliminate leakage, and minimize equipment downtime.

Applications:

The Timken 99650 Redi-Sleeve is engineered for repairing shafts that have experienced wear from radial lip seals. It installs directly over the existing shaft to provide a new sealing surface without altering the shaft dimensions or requiring extensive repairs. Typical applications include pumps, gearboxes, electric motors, industrial fans, mixers, compressors, paper mills, mining equipment, and general industrial rotating equipment.
