CRBA07013 Bore 70 Mm, Split Outer Ring Type (CRBA) Crossed Roller Bearings, Sealed And Open Type
The CRBA07013 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 CRBA07013 bearing is a Split outer ring type (CRBA) crossed roller bearings, sealed and open type with an inner diameter of 70 mm , an outer diameter of 100 mm, a width of 13 mm. It typically uses P5, P4, P2, PD5 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears radial, thrust and moment, Its dynamic radial rated load is approximately 21700 N, its static radial rated load is approximately 30600 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.
CRBA07013 bearings ( 70 mm x 100 mm x 13 mm) have the advantages of The rollers are arranged in a cross pattern, allowing them to withstand radial, axial, and overturning moments simultaneously. They offer high rigidity and rotational accuracy while compact and space-saving design, and easy installation, and are therefore widely used in the Industrial robots, CNC machine tools, medical equipment, precision measuring instruments and aerospace.

The CRBA07013 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.
