RA series(outer ring division type with inner rotating, thin section) This model is a compact type of model RB with extremely thin outer and inner rings. It is optimal for areas where the swiveling unit needs to be light and small. For example ,the rotational part of industrial robots or manipulator.
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load：This series bearing can bear double-direction axial load, radial load and tilting moment
4. Small size: This series bearing can save space for machine tools
widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
SX series(outer ring division type with inner rotating, thin section),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.
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load：This series bearing can bear double-direction axial load, radial load and tilting moment
4. Small size: This series bearing can save space for machine tools
widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
BH series（Integrated Inner/Outer Ring type）, this model is a compact type of model RU with extremely thin outer and inner rings without mounting holes are provided, the model require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. This model can be used for both inner-ring rotation and outer-ring rotation and the requirement of miniaturized dimension.
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load：This series bearing can bear double-direction axial load, radial load and tilting moment
4. Small size: This series bearing can save space for machine tools
widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
RE series (inner ring division type with outer rotating), which is also the basic type of crossed roller bearings. The size is the same with that of RB series. The inner rings have two parts, and the outer ring is one integer. The type is well apply to the situation which need high rotation accuracy on outer ring.
1. High precision: P4 precision, P2 precision
2. High rigidity: This series bearing have preload
3. High load：This series bearing can bear double-direction axial load, radial load and tilting moment
4. Small size: This series bearing can save space for machine tools
