RB Series Crossed Roller Bearings
RB series crossed roller bearing is the basic model of crossed roller bearing. It has a detachable outer ring and a united inner ring. So it is widely used for internal ring accuracy rotation. Model RB is the primary type of crossed roller bearings. The outer ring is divided into two pieces, and the inner circle is an integral structure, which is most suitable for occasions that require the rotation accuracy of the inner circle.
RB Series Crossed Roller Bearings
RB series crossed roller bearing is the basic model of crossed roller bearing. It has a detachable outer ring and a united inner ring. So it is widely used for internal ring accuracy rotation. Model RB is the primary type ofcrossed roller bearings. The outer ring is divided into two pieces. The inner ring is an integral structure, which is most suitable for occasions requiring the inner circle's rotation accuracy.
The outer ring of this type of bearing is divided into two parts in the axial direction and the inner ring as a whole; the cylindrical rollers are arranged in two 90°V-shaped raceways at a 90° included angle of 1:1, and spaces separate the cylindrical rollers. In the future, this kind of bearing will have a compact structure so that a set of bearings can bear radial load, axial load, and overturning hurdle at the same time while ensuring structural rigidity, greatly simplifying the design of the shafting structure; Can be preloaded to facilitate installation and maintenance work further.
At the same time, this type of bearing has the characteristics of High precision, High load, and high rigidity, which is very suitable for robot rotating parts, manipulator joint parts, CNC indexing workbenches, medical equipment, and measuring instruments. It is especially ideal for features requiring the inner ring's rotation accuracy.

RB Series Crossed Roller Bearing Features
1. Sustain radial, axial, and moment loads at the same time.
2. High rotation accuracy is ensured by adjusting the bearing clearance to preload.
3. Stable rotation, spacer retainer keeps rollers in the proper position, preventing them from skewing, thus eliminating friction between rollers.
Applications of RB Series Crossed Roller Bearing
RB Series crossed roller bearings are especially suitable for applications where space is limited. At the same time, high rigidity and high rotation accuracy are required—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.
Product process and test
1. Surface: Make sure the machine is cooled, and control the surface bending and parallel difference. Pickling flaw detection for the first product to see whether there is burning damage or crack.
2. Outer ring: Control ellipse, triangle, and size. Repeated grinding if it is high.
3. Inner ring: Control ellipse, wall thickness, and taper. The vertical difference should meet the requirements if it is high.
4. Raceway: Because of the particularity of this product, it needs to grind at a fixed distance and ensure that cooling is in place.
