RB2008 Crossed roller bearing 20mm*36mm*8mm outer ring division type with inner rotating), this type is the basic type of crossed roller bearings. the outer rings have two parts, and the inner ring is one integer. the type is well apply to the situation which need high rotation accuracy on inner ring. for example,it is suitable for the rotary part of the indexing table of the tools machine.
Crossed roller bearings have the structure of outer ring division type with inner rotating, inner ring division type with outer rotating, inner Ring Rotation / Outer Ring Rotation. the rolling element is cylindrical roller, cylindrical rollers are arrange crosswise with each roller perpendicular to the adjacent roller in 90V groove, separated from each other by spacer retainer. The criss-cross arrangement of the roller structure makes individual bearing can carry axial load, radial load and overturning moment in all directions. and the size of the bearing is close to the limit of ultra-thin of the structure, and the bearing has high rigidity, higher rotation accuracy and larger carry capacity. so it is well apply to the joints or rotating parts of industrial robots, the rotation of the machining center, robot rotation parts, precision rotary table, medical equipment and other applications.
