CROSSED ROLLER BEARING MANUFACTURER & SUPPLIER FOR VARIOUS MACHINES

The crossed roller bearing is one of our distinctive products for substituting the imported bearings. The every second roller is at right angles to its neighbouring rollers in the raceway between the outer ring and the inner ring, and that makes the bearing very compact. It can accomodate axial, radial and overturning moment loads acting either singly or in combination and has as 4 to 5 times rigidity as other bearings. The crossed roller bearing is highly precision in rotation and simple in Mounting.

The crossed cylindrical roller bearings for robots have compact structure. The rollers are arranged with 90° crossing between inner rings and outer rings. They are able to carry radial, axial and moment loads.

As rollers are made line-contact with raceway surfaces, the elastic deformation is little when the bearings are carried heavy loads. This type of bearings are widely used in the applications requiring high stiffness, compact structure and high accuracy, such as industrial robots, construction mechanism, medical apparatus, etc.

Crossed-roller sideways or bearings are the most accurate form of mechanical linear motion component. Also known as crossed roller slides, these bearings work similarly to ball bearing slides, except that those housed within the carriage are cylinder-shaped instead of ball shaped. The rollers crisscross each other at a 90° angle and move between the two parallel guides (alternately termed table and bed) that surround the rollers. The rollers are between “V” grooved bearing ways or raceways ground out of the guides. The travel of the moving guide/table, ends when it meets an end cap, a limiting component.

Crossed roller slides offer a line of contact, versus a ball bearing’s point contact. The line of contact creates a broader contact surface that can carry a heavier load. Such a feature offers more rigidity, less deformation, and thus more accuracy compared to the point contact of balls. Plus, due to the crossed rollers’ consistency of contact between the carriage and the base, erosion is slower. The recirculation of ball bearings creates vibration when the balls leave the load-carrying path to recirculate. Because most crossed roller bearings do not have recirculation components, this source of vibration is eliminated.
