Ball screw support bearing overview

7602 series 7603 series BS series

The nominal contact angle is 60°, the bearings can withstand large axial loads in a single direction, and can also withstand certain radial loads, and usually need to be used in groups.

ZKLF(N) series

Bi-directional thrust angular contact ball bearings can bear force in both directions, can withstand heavy loads, and have high rigidity, especially meeting the high-precision requirements of modern precision machinery. This kind of bearing has two structures with mounting holes in the outer ring and without mounting holes. The structure with mounting holes can be directly installed on the adjacent structure through bolts. economy.

ZARF(N) series

Needle roller/thrust cylindrical roller bearings adopt a combined structure of needle roller bearings with thickened outer rings and two rows of thrust cylindrical roller bearings, which can withstand greater radial/axial loads and have higher radial/axial rigidity. The inner ring, outer ring and cylindrical roller and cage assembly are matched to each other, so that a given axial preload can be applied to the bearing with precision lock nuts. There are two types of bearings with mounting holes in the outer ring and without mounting holes in the outer ring. The bearing with a hole is directly installed on the adjacent structure through the cap bolt, the contact surface is large and the hole spacing is small, so its connection with the adjacent structure is very rigid and the fixing effect is good. parts can also be omitted.

If the axial adjacent space of the shaft ring is insufficient or if sealing is required, a bearing with an extended stepped shaft ring can be selected.
