The Timken Company 99162 Repair Sleeve For Shaft

Description:

The Timken National Redi-Sleeve 99162 is a precision-engineered stainless steel shaft repair sleeve designed to restore worn, grooved, or damaged shaft sealing surfaces without requiring shaft replacement or machining. Installed directly over the existing shaft, it creates a smooth, wear-resistant, and corrosion-resistant sealing surface for standard radial shaft oil seals, extending seal life while reducing maintenance costs and equipment downtime. The 99162 Redi-Sleeve is widely used in industrial gearboxes, pumps, compressors, electric motors, conveyors, agricultural machinery, and heavy-duty rotating equipment. Maintenance teams, OEMs, and system integrators rely on this shaft repair sleeve for equipment repairs, retrofit projects, seal restoration, and preventive maintenance.

Applications:

The Timken National Redi-Sleeve 99162 is designed to repair worn shaft seal contact surfaces and restore dependable sealing performance while allowing continued use of the original shaft and standard oil seal size. Its precision thin-wall stainless steel construction provides a hardened sealing surface with minimal effect on shaft dimensions, making it ideal for industrial gearboxes, pumps, compressors, electric motors, wheel-end assemblies, conveyors, agricultural equipment, and other rotating machinery where shaft wear has caused lubricant leakage or premature seal failure.
