FRB BEARING Cross Roller Ring is a bearing with rollers arrange in vertical directions crossly among inside and outside ring of bearing.Roller contacts with roller pass by line,with good rigidity.Elastic deformation of bearing load is very little.And bearing can bear radial load,axial load,and torque load at the same time,especially applies to occasion requires high rigidity and high rotating precision.Using this bearing can simplify design and shorten shaft.The bearing is applied well in fields of robot and medical equipment.
vertical lathe,grinding machine,manipulators,hobbing machine, wheeling camera,slewing assembly fixture,industrial robotics,working table, etc.
Ⅰ).Excellent rotation accuracy
The internal structure of cross roller bearing is arranged in 90° vertical cross with each other.
An interval retainer or an isolation block is installed between the rollers to prevent the inclination of the rollers from rubbing each other.In addition, there will be no roller contact or locking phenomenon;At the same time, because the inner and outer rings are segmented, the gap can be adjusted, and even if preloading is applied, high precision rotation motion can be obtained.
Ⅱ).Simplified operation and installation
The outer or inner ring, which is divided into two parts, is fixed together after the roller and retainer are loaded, so it is very easy to install.
Ⅲ).Bear larger axial and radial loads
Because the rollers are vertically aligned with each other through an interval retainer on a 90° v-groove rolling surface.
Ⅳ).Significant savings in installation space
Cross roller bearing inner and outer ring size is minimal miniaturization, especially ultra-thin structure is close to the limit of small size, and high rigidity, so the most suitable for the joints of the industrial robot parts or rotating parts, machinery processing center of the rotary worktable, mechanical rotary department, precision rotary worktable, medical instruments, measuring instruments, such as IC manufacturing equipment widely used.
Ⅴ).High speed capability
Reducing shaft length and machining cost, thermal expansion results in limited geometric size changes
Ⅵ).Nylon separator,low inertia, low starting torque, easy to control Angle indexing
Ⅶ).Optimize the preload, high rigidity, high precision of guiding roller running
Ⅷ).Carburized carbon steel provides excellent impact and surface abrasion resistance
Ⅸ).Simple but well lubricated
