As already mentioned, SKF split spherical roller bearings are based for the most part on non-split bearings of standard design. Consequently they represent state-of-the-art engineering. All the split bearings have a cylindrical bore and an annular groove and lubrication holes in the outer ring to facilitate efficient lubrication. The joins of the inner ring are at an angle to the bearing axis in order to guarantee uninterrupted overrolling of the join. The bearing rings and cage are divided in the middle and the ring halves are held together either by screws or by clamping rings.
