JRB series (inner rotating) have two parts of the outer rings, and the inner ring is one integer. It is well apply to the situation that need high rotation precision of inner ring.
JRE series (inner ring division) have the same size of JRB series. The inner rings have two parts, and the outer ring is one integer. It is suitable for the situation that need high rotation accuracy of outer ring.
JRU series (one—piece of inner and outer ring), as the mounting holes are provided, it is no need to fix the presser flange and the housing.
The structure of the crossed cylindrical roller bearing is divided into the outer ring split and the inner ring as a whole; the outer ring as a whole, the inner ring split and the inner and outer rings are all three forms.
JRA series (outer ring division) is a kind of small size of inner /outer rings crossed roller bearing, its structure is same as to the RB series. It is best suited for robots and mechanical rotating parts need such as light weight, compact design.
JRBH series(integrated inner /outer ring type) is a compact type of model RU with extremely thin outer and inner rings without mounting holes ,so the presser flange or housing are necessary.
JSX series(outer ring division type with inner rotation) this type has smaller section than RB series.Due to the extremely thin structure, there is no mounting holes on the outer ring and the inner ring, so the model requires a presser flange or housing. It can be used for the inner ring rotation.
Crossed taper roller bearings have two sets of races and taper rollers brought together at right angles with alternate taper rollers facing in opposite directions, and with nylon separator between the taper rollers to avoid the mutual friction between rollers and the overturning effect, which reducing the rotation torque, and that can bear combined loads of radial loads, axial loads and overturning moments.
We can provide more solutions.
Our main products include cross roller bearings, rotary table bearings, rotary table bearings with internal and external teeth, thrust bearings, flexible bearings, etc. The accuracy can reach P2/P4/P5 level, with complete specifications to meet the needs of various high-end precision equipment.
