RA19013 CRBS1913 roller bearing 190x216x13mm for Transport robot
joint swivel part use
RA19013 CRBS1913 190x216x13mm 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.RA19013
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
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
Equipped with advanced manufacturing CNC Machine and test
instruments to insure the accurate tolerance , all bearings are of
uniform marking and packing with superior quality, reasonable
prices and perfect services. Meanwhile we can make the module to
test the mounting hole.
All the bearing from the forging to assembly process,It will need
to inspect step.For the bearing forging we will need to test the
size and hardness and surface, for the lathe process and grinding
process,first it will need to check by the worker ,and then the
professional inspector will checking the size and accurate,The last
step the monitor will inspect the size. It can insure zero defect.
It can calculate the load curve.
Can offer assembly drawing based on the bearing working condition
Can offer pre- sale ,sale and after sale service
