NTN Split spherical roller bearings are primarily used for bearing positions which are difficult to access such as on long shafts which require support at several positions, or on cranked shafts. Their use is also beneficial where non-split bearings would require considerable time and effort for maintenance and more particularly for replacement.Split spherical roller bearings can generally be mounted instead of unsplit spherical roller bearings with adapter sleeves. The preconditions for replacement are that the outside diameter, outer ring width and diameter of the shaft seat are identical and that the bearings are suitable for the load case.

Split spherical roller bearings are principally used where the replacement of unsplit spherical roller bearings would require costly additional work, involving the removal of gears or couplings, the dismounting of drives or the dismantling of shaft power trains. The use of split spherical roller bearings reduces the downtime of machinery and plant.NTN manufacture a range of split spherical rollers that replace standard spherical roller bearings that will replace the bearing and adapter. Split bearings are used at locations of restricted access and as replacement bearings.
