âž” fig ).With the multi-groove system SKFhas the answer to lubricant starvation in steel-on-steel bearings, which is otherwise prevalent where the bear- ings have to perform minor alignment movements under heavy constant direction loads.The multi-groove system ( âž” page 6 ) inthe outer ring sliding contact surface as standard ( âž” fig ). The bearingsare therefore non-separable and easy to handle.The surfaces are manganese phos-phated and the sliding contact surface also treated with a running-in lubricant. This makes the bearings wear resistant and easy to run-in. To facilitate effect- ive lubrication, all bearings – except some small sizes – have an annular groove and two lubrication holes in both outer and inner rings. Addition- ally, bearings with an outside diameter of 150 mm and above also have the “multi-groove system” ( A characteristic feature of the SKF steel-on-steel spherical plain bearingsis the outer ring, which is intentionally fractured at a given point so that it can be sprung apart to enable the inner ring to be inserted (
