SKF Speedi-Sleeve
SKF Speedi-Sleeve
SKF Speedi-Sleeve is a thin-walled stainless steel wear sleeve that restores a worn shaft to a precision sealing surface — without disassembling the machine, re-machining the shaft, or changing the seal size. When a radial shaft seal has scored a groove into the shaft counterface, the Speedi-Sleeve is simply pressed over the damaged area to give the seal a smooth, round, wear-resistant surface to run against again. Installation takes only a few minutes, making it the proven repair for worn shafts across pumps, gearboxes, motors and heavy machinery.Technical Properties
The SKF Speedi-Sleeve is manufactured from a proprietary stainless steel with an optimised, low-directionality counterface finish that is often better than can be achieved on the shaft itself. Its ultra-thin 0.28 mm wall presses on with an interference fit — no adhesive is needed within the shaft range — while microscopic lubricant pockets keep the sealing lip supplied and prevent dry running. A removable flange simplifies installation, and a Speedi-Sleeve Gold version with a metallic coating is available for highly abrasive duties. These seals also feature:- Wall thickness: ultra-thin 0.28 mm (0.011 in.) — fits under the existing seal without changing the seal size.
- Material: proprietary stainless steel; Gold version with a metallic coating for highly abrasive applications.
- Surface finish: Ra 0.25–0.5 µm (10–20 µin.) with minimised directionality (0° ±0.05) for an optimal seal counterface.
- Shaft size range: suits shaft diameters from 11.99 to 203.33 mm (0.472 to 8 in.); non-standard sizes available on request.
- Fit: interference (press) fit — no adhesive required within range; removable flange for easy fitting.
- Operating limits (tested): temperatures up to 110 °C (225 °F) and linear shaft speeds up to 8.6 m/s (1,700 ft/min).
- Proven performance: reduces sealing-lip wear by about 30% versus the previous generation, outperforms a chromium-plated surface by a factor of two, and showed no corrosion after 600 hours of continuous salt spray.
- Installation: fits in minutes with no shaft disassembly or re-machining.
Usage
- Restoring worn or scored shaft seal counterfaces without machining the shaft.
- Repairing shafts in pumps, gearboxes, electric motors and compressors.
- Heavy industrial, mining and construction equipment — with the Gold version for abrasive environments.
- Agricultural, off-highway and general rotating equipment.
- Any application where a radial shaft seal has worn a groove and the shaft must be brought back to a reliable sealing surface.
- A fast, cost-effective alternative to shaft replacement that extends equipment life.

Description
Product Description
SKF Speedi-Sleeve restores a worn or scored shaft to a precise sealing surface, giving a radial shaft seal the smooth, round counterface it needs to keep lubricant in and contaminants out. The thin-walled stainless steel sleeve is simply pressed over the damaged area of the shaft — with no re-machining, no disassembly, and no change to the seal size — while microscopic lubricant pockets across its surface keep the sealing lip supplied and extend seal life.
Designed to work hand in hand with SKF radial shaft seals, the Speedi-Sleeve installs in minutes and suits shaft diameters from 12 to 203 mm. A removable flange makes fitting simple and can be left in place or removed to suit the assembly, while the SKF Speedi-Sleeve Gold version adds a hard metallic coating for highly abrasive, heavily contaminated environments where a standard sleeve would wear quickly.
Characteristics
- Fast, No-Machining Repair: restores a worn shaft in minutes — no disassembly, no re-grinding, and no change to the existing seal size.
- Precision Sealing Surface: an optimised counterface finished to Ra 0.25–0.5 µm, often smoother and rounder than the shaft itself.
- Proven Wear Resistance: around 30% less sealing-lip wear than the previous generation, and twice the service life of a chromium-plated surface.
- Superior Corrosion Resistance: no trace of corrosion even after 600 hours of continuous salt spray.
- Prevents Dry Running: micro lubricant pockets keep the sealing lip supplied, reducing wear on both the sleeve and the lip.
- Flexible Fitting & Sizing: ultra-thin 0.28 mm interference fit with a removable flange; fits 12–203 mm shafts, with a Gold version for highly abrasive duty.
