RB70045 High Quality Crossed Roller Bearings(like Iko,thk)

RB series crossed roller bearings (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 applied 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.

HONB specializes in the research and development and manufacture of three series of precision rotary table bearings, cross roller bearings and robot reducer bearings. The precision grades are P2, P4 and P5, and the size range is φ20mm - φ2000mm. The quality is same with INA, THK ,IKO products.

The YRT rotary table bearings and crossed roller bearings are mainly used in high-precision CNC turntables, machine tool spindles, radars, direct drive motors, industrial robots, aerospace and other fields. The two types of market segments for product service are: 
1) High-end equipment industry: the key parts of high-end CNC machine tools - high-precision bearings for precision CNC turntables, machine tool spindles, indexing heads, and screw parts. Strategic cooperation customers include the world's largest machine tool companies, major domestic machine tool companies and military industrial enterprises.
2) Industrial automation industry: industrial robot joint bearings, robot-specific harmonics and RV reducer bearings, direct drive motor bearings. 

Crossed roller Bearings characteristics:

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

Crossed roller bearings APPLICATION:
widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
