99086 Hardened Stainless Sturdi Sleeve for Shafts 21.77-21.87mm

Sturdi® Sleeve: The quickest and most sensible way to repair a worn shaft. The Sturdi® sleeve range offers the opportunity to repair seal counter faces on shafts without prior dismantling or machining of the equipment and once fitted offers superior surface and sealing characteristics often outperforming the original life span of the shaft. Speedi Sleeves are designed to repair shafts where oil seals run. The sleeve is sufficiently thin-walled (.011" or 0.28 mm) to allow the same size of seal to be used. The Sturdi® shaft repair sleeve is made of high quality stainless steel SAE 304. The surface is wear-resistant and machined without directionality to a finish of Ra = 10 to 20 micro inches or 0.25 to 0.5 µm.
Benefits: No dismantling of equipment, longer life cycle, cost effective.
Note: Sturdi® sleeves are only suitable for repairs where an oil seals needs to run, they cannot be used to repair damage where a bearing fits onto a shaft.
