The Timken Company 99133 Shaft Repair Sleeve For Grooved Shafts

Timken National Redi-Sleeve 99133 is a precision-thin-wall stainless steel shaft repair sleeve that restores worn or grooved shaft sealing surfaces without shaft replacement or costly machining. Installed over a damaged shaft, it provides a smooth, hardened sealing surface that extends the service life of radial shaft oil seals while minimizing equipment downtime. Designed for 1.371–1.377 in shafts (nominal 1.375 in), it features a flanged outside diameter of 1.638 in, an overall width of 0.438 in, and a seal-running surface width of 0.313 in, with an installation depth of 0.813 in. The sleeve construction includes a installation flange and is compatible with standard radial shaft oil seals for 1.375 in shaft diameters. Typical applications include pumps, gearboxes, electric motors, compressors, wheel hubs, agricultural equipment, conveyors, and other industrial power transmission systems. Common replacements include SKF Speedi-Sleeve 99133 and equivalent National Redi-Sleeve 99133 or CR Shaft Repair Sleeve for 1.375 in shafts.
