SKF 99338 Speedi-Sleeve Shaft Repair Wear Sleeve 3.375 in Stainless Steel

The SKF 99338 Speedi-Sleeve is a precision-engineered, thin-walled stainless steel shaft repair sleeve designed to restore worn or damaged shaft surfaces quickly and cost-effectively. Rather than replacing or reworking a damaged shaft, the Speedi-Sleeve slips directly over the worn area to provide a smooth, optimized counterface for radial shaft seals.

This standard-version sleeve fits shafts ranging from 3.3728 in to 3.3791 in (85.67–85.83 mm) in diameter and is manufactured from high-quality SAE 304 stainless steel. The contact surface is precision-finished to a surface roughness of Ra 0.25–0.5 µm (10–20 µin) with near-zero directionality, often delivering a superior sealing counterface compared to the original shaft.

Microscopic lubricant pockets in the sleeve surface allow lubricant to reside on the sleeve, preventing dry running of the sealing lip and reducing wear on both the sleeve and the seal. Installation requires no power tools, no shaft disassembly, and no heating — making it an ideal solution for minimizing costly downtime in the field or shop.
