Crossed Roller Bearings
HIWIN’s Crossed Roller Bearings offer smooth and accurate rotational motion with minimal friction. They feature a unique crossed-roller design, which allows for high axial and radial stiffness and low rotational torque. This design also enables the bearings to support axial, radial, and moment loads simultaneously, providing high load capacity and rigidity.
This crossed-roller design consists of two raceways with two sets of rollers arranged perpendicularly between them. The rollers are preloaded to ensure maximum contact between the rollers and the raceways, resulting in high accuracy and smooth motion. The raceways and rollers are precision-machined to ensure optimal performance, and the bearings are available in various sizes and configurations to meet specific application requirements. This design also allows them to operate in extreme conditions, such as high temperatures, high speeds, and harsh environments, without compromising their performance. In addition, HIWIN offers customization options, such as coatings and seals, to further enhance the bearings’ performance and service life.
The CRBE and CRBC series are two of HIWIN’s most popular Crossed Roller Bearings, featuring a compact design and high load capacity. The CRBE series has an integrated inner ring and separable outer ring, making it easy to install and maintain. The CRBC series, on the other hand, features a full complement of rollers for maximum load capacity and rigidity. Both series feature a precision-machined bearing raceway and crossed roller elements, resulting in high axial and radial stiffness and low rotational torque.
