Linear bearing and guides for smooth motion system performance

Cross-roller bearings leverage cylindrical rollers instead of balls to increase the surface area supporting the load. Within the bearing, the rollers are positioned orthogonal to one another; hence, the name. This enables the bearings to easily support loads from multiple directions. Cross-roller bearings are good for high-precision appliions.

Crossed Roller Bearings

Rolling Bearings Crossed Roller Bearings HIWIN crossed roller bearings consist of an inner ring, an outer ring, and cylindrical rollers arranged at 90° with spacers between them. This crosswise arrangement of cylindrical rollers means that only the one bearing can absorb axial forces from both directions, radial forces,

High precision and super light - Schaeffler Group

roller bearing sets or crossed roller bearings are used. Furthermore, thin section bearings offer the possibility of reducing design envelope and mass. The small cross-section of these bearings and the rolling contacts of the balls, however, lead to lower basic load rating values. The load carrying capacity, rigidity and rating life are

Factors To Consider When Choosing A Crossed Roller Bearing

Jan 10, 2018· However, their low load capacity, short life and oscillating positioning load as the bearings recirculate, put them at a disadvantage compared to crossed roller bearings. Crossed roller slides offer a line of contact versus a ball bearing’s point contact, creating a broader contact surface that can carry a heavier load.
