Spherical roller bearings

The Split spherical roller bearing has two rows of symmetrical rollers, two inner ring raceways inclined at one angle relative to the bearing axis, and a shared spherical raceway on the outer ring. They are designed to bear heavy radial loads and can be loaded with or without axial loads in both directions. These bearings are suitable for both fixed and non-locating bearing positions on shafts. Mounting, dismounting, and maintenance in inaccessible applications are challenging, and the split design of split spherical roller bearings perfectly solves this problem.

• Characteristics of split spherical roller bearings

• The split spherical roller bearing has the same self-aligning ability as the integral spherical roller bearing;

• The inner ring, outer ring, and cage with roller set are divided into two halves from the axial direction of 180°, and the separated bearing rings are fixed together with screws;

• The cost savings of split spherical roller bearings are particularly obvious: the birth of split spherical roller bearings is mainly due to the expensive and time-consuming additional work required to replace integrated spherical roller bearings, including the disassembly of gears or coupling, remove the drive or remove the shaft power system. The use of split spherical roller bearings reduces machine and plant downtime;

• Easy to install and disassemble. Split spherical roller bearing units can be disassembled into smaller components, simplifying lifting and handling tasks and making installation or replacement simple, even in the tightest, out-of-reach conditions. Play is preset, so no field adjustments or specialized installation tools are required.

• Structural design of split spherical roller bearings

• Split spherical roller bearings are primarily based on the standard design of non-split bearings. Therefore, these bearings represent the latest engineering technology. All split bearings have a cylindrical bore with lubrication holes and an annular groove in the outer ring for easy and effective lubrication. The joint line of the split inner ring forms a certain angle in the axial direction to avoid continuous excessive joint rolling. The bearing ring and the cage are separated from the middle, and the half rings of the bearing ring are fixed with screws. The bearing cage is made of glass fiber-reinforced polyamide or brass cage.

FV also designs split spherical roller bearings with separate locking rings for special applications, as shown below:

The figure below shows two different cage designs, fiberglass reinforced polyamide cages or brass cages corresponding to bearing suffixes TVPA and MA, respectively.
