The Timken Company 99156 Redi Sleeve Shaft Repair Sleeve

Description:

The Timken National Redi-Sleeve 99156 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 99156 Redi-Sleeve is commonly 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 99156 is designed to repair worn shaft seal contact surfaces while allowing continued use of the original shaft and standard oil seal size. Its precision thin-wall stainless steel construction restores proper sealing performance with minimal change to 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.
