MRC: Radial cylindrical roller bearings, full complement, fixed bearings

 

MRC

Full complement cylindrical roller bearings incorporate the maximum number of rollers and, as a rule, have a low sectional height in relation to their width. This produces an extremely high load carrying capacity and permits spacesaving designs to be achieved; however full complement cylindrical roller bearings can not operate at same high speeds as cylindrical roller bearings of the conventional caged type. Some of these bearings are more suitable for axial loads than high radiai loads. All the components form a unit ready for assembling.

Designations MRC 48 e MRC 49

These bearings have the outer ring split in two halves and an integral flage on one side. These two halves are connected by retaining rings, whose number varies in relation to the diameter of the bearing. These type are therefore able to bear axial loads in both directions and can be used to constrain axially the shaft in both directions.

Tolerances and clearances

Bearings of this type have a dimensionai and running accuracy corresponding to tolerances class PO according to DIN 620 and with CO radiai internai clearance. They are also available from C2 to C4 radiai clearance groups, on request. On customer’s request they can be manufactured also with different tolerances and radiai clearances to normal.
