RB Series Crossed Roller Bearings
RB Series crossed roller bearing series (outer ring division type with inner rotating). This type is the primary type of crossed roller bearings. The outer rings have two parts, and the inner circle is one integer. The class is well applied to the situation requiring high rotation accuracy on the inner circle. For example, it is suitable for the rotary part of the indexing table of the tools machine.
