Timken 99118 Stainless Steel Shaft Repair Sleeve

Description:

The Timken National Redi-Sleeve 99118 is a precision-engineered stainless steel shaft repair sleeve designed to restore worn, grooved, or damaged shaft sealing surfaces without replacing or machining the shaft. Installed directly over the existing shaft, it creates a smooth, wear-resistant sealing surface that extends the service life of radial shaft oil seals while reducing maintenance costs and equipment downtime. The 99118 Redi-Sleeve is commonly used in industrial gearboxes, pumps, electric motors, compressors, conveyors, agricultural machinery, and heavy-duty 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 99118 is designed to repair worn shaft seal contact surfaces and restore proper sealing performance while allowing the continued use of standard radial shaft oil seals. It is 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. Its thin-wall stainless steel construction provides a durable, corrosion-resistant sealing surface with minimal change to shaft dimensions.
