NRXT11020 Bore 110 Mm, Sealed Crossed Roller Bearings (thin-cross Section Bearings)
The NRXT11020 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 NRXT11020 bearing is a Sealed Crossed roller bearings (thin-cross section bearings) with an inner diameter of 110 mm , an outer diameter of 160 mm, a width of 20 mm. It typically uses ISO Class 5; Class Normal grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears radial, thrust and moment, Its dynamic radial rated load is approximately 35000 N, its static radial rated load is approximately 59000 N. It uses C8: Negative clearance; C1: Positive clearance standard radial clearance, DD = Two Sides Seals; E = Open type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
NRXT11020 bearings ( 110 mm x 160 mm x 20 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 NRXT11020 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.
