This adapter sleeve provides a mechanical fit between a bearing with a tapered bore and a cylindrical shaft, allowing the bearing to be mounted at any point along the shaft rather than only at a shoulder. It has a bore diameter of 60.0 mm and a net mass of 470.86 g, with a standard design construction. The sleeve is supplied complete, ready for mechanical mounting. By taking up the tolerance gap between the shaft and the tapered bore, the sleeve allows the internal clearance of the bearing to be set precisely during installation through controlled axial displacement on the taper. This makes it suited for applications where the bearing position on a plain shaft section must be adjustable, and where mounting without a shaft shoulder is required.
