Combined Precision Roller Bearings
Rolling Bearings
Combined precision roller bearings are similar to two-directions axial needle or cylindrical roller bearings, which have a radial part between the running rings. A reinforced outer ring with a needle cage or a full-complement needle collar and an inner ring serves with its end faces as a running surface for the axial bearings. The inner ring is enclosed between the side rings.
These precision bearings are available with or without mounting holes in the outer rings. The last one can be screwed directly onto the construction.
In addition to radial forces, the combined roller bearings also absorb axial forces from both directions and allow very rigid and play-free bearings in e.g. leading spindles, infeed axis, ball screws or drive spindles.
Rotary Table Bearings
Axial-Radial Bearings
Axial-radial bearings or rotary table bearings are ready-to-install, easy-to-assemble, screw-on, double-acting axial bearings with radial guide bearings, which are particularly stable, rigid and precise.
Accordingly, they absorb axial and radial loads and tilting torques on both sides without play and are used in applications with high demands on running accuracy.
