CRBT Series Cross Roller Bearing, Is an ultra-thin type cross roller bearing which reduces the thickness of the inner and Outer Rings of the CRBS type to the limit, most suitable for light weight, structure design needs very compact parts, for example, small and light service robots, cooperative robots, Android, exoskeletons, radar communications, head and medical devices, such as rotating support parts.

1. CRBT155 Crossed roller bearing Structure
The Cross roller bearing is arranged by the rollers in a straight line. The Cross section area of the single row roller bearing and the ball bearing with a contact angle of 45 ° mounted back to back is reduced to one size. Not only the structure is compact, but also the rigidity is improved to 3 ~ 4 times of the double row angular contact ball bearing.

2.CRBT155 Crossed roller bearing Features
With intergrated inner ring and outer ring,High rigidity and high accurancy together with somooth rotation is provided by separator, can be used for both inner ring and outer ring rotation.
- High precision: P4 precision, P2 precision
- High rigidity: This series bearing have preload
- High load:This series bearing can bear double-direction axial load, radial load and tilting moment
- Small size: This series bearing can save space for machine tools
3. CRBT155 Crossed roller bearing Applications
Widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
