Timken National Bearings 99149 Shaft Repair Sleeve

The Timken National Redi-Sleeve 99149 is a precision-thin-wall stainless steel shaft repair sleeve that restores worn or damaged shaft sealing surfaces without shaft replacement or machining. Installed directly over the existing shaft, it creates a smooth, wear- and corrosion-resistant running surface compatible with standard radial shaft oil seals and extends seal life in gearboxes, pumps, compressors, electric motors, conveyors, agricultural equipment, wheel hubs, and other heavy-duty rotating machinery. This sleeve belongs to the Redi-Sleeve 99000 Series and is designed for shafts in the 1.497–1.503 in range (nominal 1.500 in), with a flanged outside diameter of 1.781 in, a seal-running width of 0.563 in, and an overall width of 0.688 in; installation depth is 1.000 in. It is made from precision-ground stainless steel with a lead-free running surface, weighing approximately 0.16 lb. Compatible with standard radial shaft seals for about 1.500 in shaft diameters, and commonly paired with equivalents such as SKF Speedi-Sleeve 99149 or National Redi-Sleeve 99149, this sleeve allows continued use of the existing shaft and seal size for repairs and preventive maintenance.
