SKF · Seals & Gaskets · Shaft Wear Sleeves (Speedi-Sleeve)
SKF 99121 skf speedi-sleeve shaft wear sleeve. Thin-wall stainless-steel wear sleeve fitted over a worn shaft surface to provide a new, ground counterface for a radial shaft seal — restoring the shaft without machining or welding. Installation-driver tool positions the sleeve; the installation flange is broken off after fit. Suitable diameter range 11.5–203 mm. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
