What is a cross roller bearing

Crossed roller bearings are a special type of bearing with a different internal structure from ordinary bearings, which have high rotational accuracy and rigidity and are widely used in various mechanical equipment.

The structure of a crossed roller bearing consists mainly of inner and outer rings, rollers, and a cage.The inner and outer rings serve as the outer and inner rings of the bearing, respectively. The rollers are evenly distributed between the inner and outer rings, and the cage separates the rollers to prevent them from colliding with each other.The arrangement of the rollers on the inner and outer rings of a crossed roller bearing is crosswise, which is the source of its name.

The characteristics of cross-roller bearings are high precision, high rigidity, and low noise.Due to the special arrangement of rollers, the rotational accuracy of the bearing can be very high. At the same time, the optimization of material selection and processing technology for inner and outer rings and rollers enables the bearing to have high rigidity and low noise characteristics.In addition, the cross-roller bearing has a compact structure and is easy to install, making it suitable for use in various mechanical equipment.

Features of Crossed Roller Bearings

1. High precision: The inner and outer rings of the crossed roller bearing are precision-machined, and the accuracy of the ball is also very high, thus providing high-precision support and rotation.

2. High rigidity: The rolling elements of the crossed roller bearing are precision-ground cylindrical balls, which provide high-rigidity support and rotation.

3. Low friction: The contact area between the rolling elements and the inner and outer rings of the crossed roller bearing is small, and the friction torque is also small, thus providing low-friction support and rotation.

4. High temperature resistance: The material of the crossed roller bearing has been specially treated to withstand high temperature environments while maintaining high precision and rigidity.

5. Strong preload capability: Crossed roller bearings can provide preload function, which can be adjusted according to different application requirements to improve the accuracy and rigidity of the equipment.

6. Compact structure: The cross roller bearing has a compact structure and occupies a small space, which can save space for equipment and improve the compactness of the equipment.

Long service life: Due to the high precision, high rigidity, and high temperature resistance characteristics of cross-roller bearings, their service life is long, which can reduce the maintenance and replacement costs of equipment.

In short, cross-roller bearings have many advantages, making them widely used in many fields.In the future, with the continuous development and advancement of technology, the application fields of cross-roller bearings will become more extensive.
