Retained Type Bearings (BR):
This bearing has integral lips on the outer race to provide a surface for axial load. This axial load is accommodated on the inner race via the hardened clamp rings, which both align the inner race halves and provide roller guidance. In larger bearings the inner race is manufactured with integral ribs for roller guidance and axial load.
This type of bearings will locate the shaft axially as well as provide a means for taking axial load. The retained outer race must be fixed sideways against one of the housing grooved shoulders using the pins and screws provided. Only one retained unit should be mounted on any particular shaft. Additional care should be taken when mounting split rolled bearing unit on shafts using other, non-split types of bearings 9ball, cylindrical and spherical roller etc.) to ensure there are no other locating bearings used.
Expansion Type Bearings (BX):
This bearings is designed for radial loads only. As in the retained type bearing, the rollers are guided on the inner race by the hardened shoulders of the clamping rings.
During expansion or contraction of the shaft, rollers are free to move across the plain outer race offering virtually no resistance to axial movement.
For both the types above Split Roller Bearing offers a range of bearing "series", providing solutions for a wide range of operating conditions. These are Light, Medium and Heavy Series offer an increasing ability to accommodate higher loads.
Light Series bearing products are by far the most commonly utilised range within the Split Bearing range. With a wide variety of mounting and sealing solutions available, the light Series bearing units can be easly matched to an increasing range of applications.
Medium Series bearing products can be utilised in applications requiring higher load carrying capacity. Under nominal conditions, Medium Series may also be selected to provide an extended bearing life when compared to Light Series. Medium Series offers the same range of mounting and sealing solutions as Light Series, with the exception of Hanger units.
Heavy Series bearing products offer solutions to the most demanding of load conditions. Bearings are supported by robust and durable mountings and can be equipped with a variety of sealing solutions.
