Specifications: Most spherical bearings have an outer raceway that is a portion of a sphere and as such they are internally self-aligning. Each roller has a curved form at right angles to the direction of rotation, which conforms relatively closely to the inner and outer raceways. This gives this bearing high radial load carrying capacity. Applications for these bearings include heavy support rollers, ship line shafts and rudder shafts, crankshafts, rolling mills and grinding machines. This Ref.. Include cylindrical bore and tapered bore(K)(, also with brass cage(MB) and steel cage (CC) Ref.
