Description Type
[IKO bearings] Crossed Roller Bearings are rollers that are arranged orthogonally between the inner and outer rings and are compact bearings. Rolling contact surface, so the bearing load caused by minimal elastic deformation, and can carry radial load, axial load and torque and other complex loads.
This bearing is widely used in industrial robots, machine tools and medical equipment that require small high rigidity and high rotation accuracy.
Cross roller bearing features:
High Rigidity Type Crossed Roller Bearings
Both inner and outer rings have a solid one-piece construction. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized.
As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotational speed is comparatively high.

Standard Type Crossed Roller Bearings
The outer ring is made of two split pieces, which are bolted together to prevent separation during transportation or mounting. So, handling is easy.

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 

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

While the basic performance is on a level with that of High Rigidity Crossed Roller Bearings and Mounting Holed Type High Rigidity Crossed Roller Bearings, the
establishment of a dedicated production site and the revision of design and manufacturing processes have enabled cost reductions and shortened lead times.
This product contributes to machinery/equipment cost reductions and shorter delivery times.high.
