About This Adapter Sleeve

This product is an adapter sleeve, which acts as an interface between a cylindrical shaft and a bearing with a tapered bore. The H317 designation is a standardized part number, meaning its dimensions are consistent across major manufacturers. The sleeve is mounted by first sliding it onto the shaft. The tapered-bore bearing is then pushed onto the sleeve, and a locknut (KM17) is used to force the bearing up the tapered surface until the correct fit is achieved. This process creates a secure friction fit. The assembly is then locked in place with a lock washer (MB17). This method is a simple and effective way to mount bearings that would otherwise require a stepped or precision-machined shaft.
