The CRBF5515ATUUC1 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 CRBF5515ATUUC1 bearing is a Sealed High Rigidity Crossed Roller Bearings (Mounting Holed Type) with an inner diameter of 55 mm , an outer diameter of 120 mm, a width of 15 mm. It typically uses P0 (ISO Class NORMAL / ABEC-1) grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears radial, thrust and moment, Its dynamic radial rated load is approximately 20100 N, its static radial rated load is approximately 27700 N. It uses C1 standard radial clearance, UU = Two sides sealed type, Special synthetic rubber. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The CRBF5515ATUUC1 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.
