Description: CYJIR inner ring is processed through heat treatment
and precision machining, tolerance of dimension
and geometric accuracy accords to the national standard. There is guiding chamfering at the two ends of the
bearing race of the inner ring, which is convenient for installation. They are used for situation when the axis can not be processed with heat treatment
and can not be treated as
bearing race. When the needle rollers with inner ring
and without ring are used together, normal working windage can be reached.
Inner ring tolerance of LR is more than IR,
terminal facet is not grinded, the price is low
and they are usually used together with needle
roller bearing with pressed outer ring.
