HONB ball screw support bearings

7602 series 7603 series BS series

The nominal contact angle is 60°. This bearing can bear a large axial load in a single direction and can also bear a certain radial load. It is usually used in groups.

Bidirectional thrust angular contact ball bearings can bear force in both directions, can withstand heavy loads, and have high rigidity, especially in line with 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. This structure saves the need to process the bearing end cover to match the bearing, so it is particularly economy.

Needle roller/thrust cylindrical roller bearings use a combined structure of a thickened outer ring needle roller bearing and two rows of thrust cylindrical roller bearings, which can withstand greater radial/axial loads and have higher radial/axial load resistance. rigidity. The inner ring, outer ring and cylindrical roller and cage assembly match each other so that a given axial preload can be applied to the bearing using a precision lock nut. This kind of bearing has two types: the outer ring with mounting holes and the outer ring without mounting holes. Bearings with holes are directly installed on adjacent structures through cap bolts. The contact surface is large and the hole spacing is small. Therefore, the connection stiffness with the adjacent structure is very high and the fixing effect is good. The original bearing end caps and fittings for fixed bearings are required. Parts can also be omitted.

If the axial adjacent space of the shaft ring is insufficient or needs to be sealed, a bearing with an extended stepped shaft ring can be selected.
