Dimensions and mounting:

Two rows of spherical rollers run on a common sphered outer raceway, so the bearing carries heavy radial load together with thrust in either axial direction. The inner ring swivels inside the outer ring to absorb shaft deflection and angular error between housings. The 1:12 tapered bore mounts on an H306 adapter sleeve, which has a 25 mm cylindrical shaft seat and a 30 mm tapered outside diameter, secured by a KM6 locknut and an MB6 lockwasher. The W33 groove and three radial holes feed lubricant from the outer ring to the rolling elements.
