Speedi-Sleeve avoids need for repair of seal-worn shafts

SKF’s Speedi-Sleeve is a 0.28mm thick, metallic protective sleeve that fits over radial shaft to prevent abrasion and costs a small fraction of the potential repair bill. It can be used across a range of industries, including off-highway, mining and cement production, and on appliances including industrial pumps, gearboxes and motor shafts. A removable flange on the SKF Speedi-Sleeve simplifies installation, and can be left in place as long as it does not interfere with other components or reduce lubricant supply to the seal. Tiny pockets on the sleeve’s surface help to trap lubricant, to prevent dry running of the seal that creates excess wear. Also available is SKF Speedi-Sleeve Gold, which is said to give higher abrasion resistance thanks to a thin surface coating on the device that increases durability. This version aimed at environments where there are abrasive contaminants, and is particularly effective when combined with SKF Duralife filled-PTFE seals. The SKF Speedi-Sleeve range is available in shaft diameters from 12 to 203.2mm, though non-standard sizes can be made for diameters of 211 to 1143mm.
