CRBH8016 Bearing 80x120x16mm stock and price use for robot machine
CRBH8016(Integrated Inner/Outer Ring type), CRBH8016 is a compact type of model RU with extremely thin outer and inner rings
without mounting holes are provided, the model require a presser flange or housing. In addition, because it has an integrated
inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure,
ensuring stable rotation accuracy and torque. CRBH8016 can be used for both inner-ring rotation and outer-ring rotation
and the requirement of miniaturized dimension. According to customer needs, we can produce: CRBH8016UUC1P2, CRBH8016UUC2P4, CRBH8016UUT1P5.
Structure features of CRBH series crossed roller bearing:
With the Crossedroller bearing, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller,
in a 90°V groove, separated from eachother by a spacer retainer. This design allows just one bearing to receive loads in all directions including,
radial, axial and moment loads. Since the CrossedRoller bearingachieves high rigidity and the precision can reach up to P4.P2,
despite the minimum possible dimensions of the inner and outer rings,it is optimal for applications such as joints and swiveling
units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables,
medical equipment, measuring instruments and IC manufacturing machines.
The spacer retainer fitting among crossarrayed rollers prevents rollers from skewing and the rotation torque from increasing
due to friction between rollers. Unlike conventional types using steel sheet retainers, the CRBH crossed roller bearingdoes
not cause displacement or locking of rollers and provides a stable rotation torque. The bearing clearance can be adjusted.
In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.
CRBH crossed roller bearing body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other.
Thus, it is easy to handle the rings when installing this type.
