The CRBF108ATUD 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 CRBF108ATUD bearing is a Sealed High Rigidity Crossed Roller Bearings (Mounting Holed Type) with an inner diameter of 10 mm , an outer diameter of 52 mm, a width of 8 mm. It typically uses ABEC-1; ABEC-3; ABEC-5; ABEC-7; ABEC-9 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears radial, thrust and moment, Its dynamic radial rated load is approximately 2910 N, its static radial rated load is approximately 2430 N. It uses T1; C1; C2 standard radial clearance, UD = One side sealed in the opposite direction to counter bored mounting holes on outer ring type, Special synthetic rubber. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.

The CRBF108ATUD 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.
