The CRBH 12025 A C1 P4 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 CRBH 12025 A C1 P4 bearing is a High Rigidity Crossed Roller Bearings Open type with separator with an inner diameter of 120 mm , an outer diameter of 180 mm, a width of 25 mm. It typically uses P4 (ISO Class 4 / ABEC-7) grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears radial, thrust and moment, Its dynamic radial rated load is approximately 73400 N, its static radial rated load is approximately 108000 N. It uses C1 standard radial clearance, Open type type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The CRBH 12025 A C1 P4 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.
