Cross Roller Bearing RU42 for Robot Arm RU42UU Slewing Ring Bearings

Description

  Cross roller bearing is a special type of bearing with inner ring segmentation and outer ring rotation. Due to its special structure, it is commonly used as a joint bearing in industrial robots.
  This type of bearing involves installing two sets of bearing raceways and rollers crosswise at right angles, with adjacent rollers facing opposite directions. Isolation blocks are installed between the rollers, and support washers are also installed on the rollers, allowing the two and a half rows of rollers to be accommodated in the same space. The included angle and conical geometry of the bearing make the effective span of the bearing several times larger than the actual width of the bearing itself.
  It is mainly used in precision rotary indexing tables for machine tools, vertical and horizontal boring machines, vertical grinders, rotary surface grinders, large hobbing machines, gun and radar turrets, large radios and Optical telescope, rotary cameras, steering pivots and continuous casting machines.
