CRBS 1008 V UU Sealed Slim Type Crossed Roller Bearings Full Complement
The CRBS 1008 V UU 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 CRBS 1008 V UU bearing is a Sealed Slim Type Crossed Roller Bearings Full complement with an inner diameter of 100 mm , an outer diameter of 116 mm, a width of 8 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 9850 N, its static radial rated load is approximately 19300 N. It uses T1; C1; Normal standard radial clearance, UU = Two sides sealed; U = One side sealed type, Special synthetic rubber. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
CRBS 1008 V UU bearings ( 100 mm x 116 mm x 8 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 CRBS 1008 V UU 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.
