Mounting Timken® Tapered Bore Spherical Roller Bearings1) or on cylindrical shafts with tapered sleeves. The sleeves are either adapter or withdrawal configurations (Fig. 2 and 3). Correct shaft mounting is Cylindrical roller bearings | SKFWith a cylindrical or tapered bore, and open or sealed design, these bearings can accommodate very heavy radial loads because of the high number of rollers
