Deep groove ball bearings Non-separable, for operations at high speeds, of simple design and little maintenance, RKB deep groove ball bearings are the most versatile and popular bearings in rolling applications. The internal designs are the Conrad assembly (the majority of the production) and the filling slot assembly (for special applications with cage or with full ball complement). The single row deep groove ball bearings can take radial and double direction axial loads. They have limited abilities to compensate for errors of misalignment. Because of the values, in order to avoid inadmissible...

The axial clearance is generally not standardized and depends on the values of the radial clearance, ball size and raceway radius. The cage depends on the bearing series and size; RKB single row deep groove ball bearings are supplied with one of the following designs: ribbon type cage of steel or brass sheet, riveted type of steel or brass sheet and machined brass type centered on balls, inner ring or outer ring. Large size bearings are also available in special executions such as lubrication grooves in the guiding surfaces of machined brass cage (suffix MAS or MBS) and/or one notch in the outer...

Single row angular contact ball bearings RKB single row angular contact ball bearings are designed to accommodate combined loads acting in radial and axial direction. They can take axial loads in one direction only. When radially loaded, in the bearing occurs an axially acting load which has to be compensated. For this reason one bearing or paired bearings are mounted on each shaft end. These bearings are not separable and their use at relatively high speed is allowed. Manufactured in various constructive versions, they can be with different contact angles, depending on the RKB produces two types...

FOUR-POINT ANGULAR CONTACT BALL BEARINGS RKB four-point angular contact ball bearings are single row bearings where the raceway is designed to accommodate significant axial loads in both directions. Generally they have contact angle of either 35° or 45°. They need less axial space than double row or paired angular contact ball bearings. The four-point contact ball bearings have a split two-part inner (bearing designation QJ) or outer (bearing designation Q) ring, allowing a large number of balls to be incorporated, thus providing a high load carrying The bearings are of separable design of the...

Double row angular contact ball bearings RKB double row angular contact ball bearings are equivalent to two single row paired angular contact ball bearings in the arrangement back-to-back or face-to-face. So they can accept radial loads together with axial loads acting in both directions. The width is narrower than the two equivalent single row bearings in pair. The large double row angular contact ball bearings of RKB production range include bearings specially designed for rolling mills (bearing designation series 305 followed by three numbers). The standardized items of the series ISO 32 and...

Cylindrical roller bearings RKB produces cylindrical roller bearings in various design styles, sizes and dimension series. RKB heavy duty radial cylindrical roller bearings are designed to provide the highest possible radial capacity for the given cross section and to perform under heavy radial loads. These bearings incorporate improved internal proportions developed through computer assisted optimization studies, to make the maximum use of the total available cross-sectional area. The rollers have controlled contour to redistribute end stress concentration and provide more uniform distribution...

Depending on size and design, the bearings are equipped as standard with one of the following cages: un hardened pressed steel roller centered, one-piece window type brass inner or outer ring centered, two-piece machined brass roller centered (suffix M) or outer ring centered (suffix MA) or inner ring centered (suffix MB) and steel pin-type for pierced rollers. Lubrication grooves in the guiding surfaces of machined brass cages are also available (suffix MAS and MBS). RKB cylindrical roller bearings undergo a special heat treatment of stress relieving which allows them to be operated The tolerances...
