RB80070 Crossed Roller Bearing|Precision CNC Bearings|800*950*70mm
The RB80070 bearing is a Crossed Roller Bearing RB Series with an inner diameter of 800 mm , an outer diameter of 950 mm, a width of 70 mm. It typically uses P2/P4/P5 grade precision tolerances and two side seals type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

(Separable Outer Ring, Type for Inner Ring Rotation)
RB80070 is the basic model of the Cross Roller Ring, despite the minimum possible dimensions of the inner and outer rings, its outer ring is separable while the inner ring is integrated with the main body. This model is used in locations where the rotation accuracy of the inner ring is required.

RB80070 Crossed roller bearings are bearings for precision applications that correspond in their dimensions to ISO dimension series 18 in accordance with DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings. Due to the X arrangement of the rolling elements, RB80070 Cross Roller bearing can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads with a single bearing position. This allows designs with two bearing positions to be reduced to a single bearing position.RB80070 Cross Roller bearing are very rigid, have high running accuracy and are supplied with normal clearance, little clearance or preload.
C. Feature of Crossed Roller Bearing
1. High accuracy and load capacity. Precision ground V grooved ways and rollers.
2. Withstands force in any direction. Alternately crossed rollers 45º angle.
3. Easy Installation and get used to small spaces. Threaded mounting holes in standard pattern.
4. Factory preloaded for minimum axial play and low coefficient of friction.
D. Product Application
•Industrial Robotic arm,Reducer drive
•Percision Turntable,NC rotary table
•Rotation part of Machine tools
•Inspection instrument,Medical equipment
•Aero&Aviation equipment,Military radar etc
