Crossed roller bearing RA11008 110x126x8mm for Vertical articulation Welding robot

Crossed roller bearing RA11008 110x126x8mm for Vertical articulation Welding robot

RA11008 Crossed roller bearing structure:
It consist of outer ring ,inner ring and small roller and spacer.Each roller in a crossed roller bearing is crossed at a 90° angle,which is able to handle the loading force from multiple direction at the same time. RA crossed roller bearing series belong to outer ring split in half, the inner ring whole unit.RA11008 Bearing belongs to light and compact type with thinnest possible inner and outer ring.It is suit for place that weight reduction and downsizing are required,such as the hand swiveling unit robots and manipulators.
The ring and roller material are GCr15.

Super Slim Type Crossed Roller Bearings
This Type is extremely compact bearing having 5.5mm of sectional height and 5mm of width.
Separators are incorporated between Cylindrical rollers for smooth rotation. These compactness, lightness and smoothness contribute downsizing of the machine and saving driving power.

Slim Type Crossed Roller Bearings
These bearings are slim bearings having a small outside diameter, in comparison with the bore diameter,
and a narrow width. The type with cage and the type with separator provide smooth rotation and are suitable for applications where rotational speed is comparatively high.

Mounting Holed Type
High Rigidity Crossed Roller Bearing
Mounting holes are prepared on outer ring and inner ring providing easy mounting together with high rigidity and high accuracy.

【What do robots have to do with Crossed Roller Bearings?】
Robots are currently working across a range of fields including medical robots and industrial robots for welding or part pickup.
These robots are evolving towards higher functions, higher performance, and higher quality,
which require high performance bearings to support their movement.
For example, the bearings supporting the swing of the arm-type robot in the figure at the right must withstand
the high load derived from high speed operation and complex motion.
Furthermore, they must not only stand up to this severe load, but also require high accuracy to enable precise motion.
Crossed Roller Bearings were created to be used in this demanding robot-specific environment.
