Overview
The SKF CR Speedi-Sleeve 99120 is a precision-engineered shaft repair sleeve that provides a cost-effective alternative to traditional shaft restoration. Designed for shafts in the 1.154–1.158 inch diameter range, this ultra-thin stainless steel sleeve is installed directly over the damaged section of a shaft to restore a smooth, optimized sealing surface. The SKF Speedi-Sleeve 99120 eliminates the need for expensive shaft resizing, metalizing, hardening, plunge grinding, or complete shaft replacement.
