The un-split spherical roller bearings can now be replaced with more cost efficient ‘Split’ spherical roller bearings, reports CBC Australia . The Split bearing cuts costly work in the removal of gear, dismounting drives and dismantling shaft power train. Not only does it cut down costs of running machinery, it effectively reduces overall plant downtime as a result.
Split spherical roller bearings have the exact same tolerances of un-split roller bearings. They also have the same internal clearance of un-split spherical roller bearings with a cylindrical bore.
They have cylindrical bores with the inner ring, the outer ring, cage and roller set split in the middle. The internal design of most spherical roller bearings are based on the proven and tested spherical bearing E1.
The main difference between the bearings is that in some larger bearings, a rigid central rib is located on the inner ring.
