Crossed Roller Bearing

time:2023-05-16   pv:9

With the rapid development of domestic high-precision processing equipment, and the domestic technology become more sophisticated, more and more CNC rotary tables, vertical machining centers, vertical lathes, grinders and other precision CNC machining equipment abandon traditional design, and adopt better performance crossed roller bearings. With the characteristics of high rotation accuracy and speed, large carrying capacity, small size, high rigidity and so on, it has wider application and more advantages.

Crossed roller bearing also called cross-roller ring, the rolling element is generally cylindrical roller or tapered roller, the rollers are crossed in raceway and isolated by spacer or cage. The criss-cross arrangement of roller structure makes individual bearing can carry axial load, radial load and overturning moment in all directions. Compared with the traditional structure of bearings, the rigidity is increased by 3-4 times. It's suitable for a variety of industrial rotating parts, rotary tables and other applications.

Crossed cylindrical roller bearings are constructed in such a way that both the outer ring and inner ring are integral. The rolling element is cylindrical roller, which are arranged vertically in the V-shaped raceway at 90° and seperated by spacers.
