CRBFV11528AUUC1 Mounting Holed Type High Rigidity Crossed Roller Bearings V Open Type With Separator
The CRBFV11528AUUC1 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 CRBFV11528AUUC1 bearing is a Mounting Holed Type High Rigidity Crossed Roller Bearings V Open type With Separator with an inner diameter of 115 mm , an outer diameter of 240 mm, a width of 28 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 84300 N, its static radial rated load is approximately 138000 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.
CRBFV11528AUUC1 bearings ( 115 mm x 240 mm x 28 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 CRBFV11528AUUC1 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.
