The CRBE21040C Crossed roller bearings are suitable for high-precision, high-rigidity, and space-constrained rotary applications. Classic applications include industrial robot joints and positioners, CNC machine tool rotary tables and indexing heads, medical CT scanner rotating frames, radar antenna rotation mechanisms, precision measuring instruments, and aerospace simulation rotary tables.

The CRBE21040C bearing is a High rigidity with mounting holes (CRBE) crossed roller bearings, sealed and open type with an inner diameter of 210 mm , an outer diameter of 380 mm, a width of 40 mm. It typically uses P4, P2 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears radial, thrust and moment, Its dynamic radial rated load is approximately 142000 N, its static radial rated load is approximately 286200 N. Its dynamic axial rated load is approximately 315000 N, its static axial rated load is approximately 650000 N. It uses C1: Positive clearance; C8: Negative clearance standard radial clearance, WW: Double sides Sealed type; NN: Open type type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The CRBE21040C Crossed roller bearings consist of inner and outer rings, cylindrical rollers, spacers, and seals. The rollers are arranged at 90° intervals within a V-shaped raceway, allowing for multi-directional load bearing even in a single row.

Crossed roller bearings can simultaneously withstand radial loads, bidirectional axial loads, and overturning moments. They possess extremely high rigidity and rotational accuracy, and their compact structure saves installation space, simplifying machine tool design.
