XSI141094-N Crossed Roller Slewing Ring, Standard Series 14, Internal Teeth
The XSI141094-N Crossed roller slewing bearings are widely used in requiring high levels of rotational accuracy, rigidity, and load-bearing capacity, where installation space is often limited，such as industrial robots (joints, rotary seats), CNC machine tools (rotary tables, turrets), medical equipment (CT scanners, surgical robots), precision measuring instruments, radar turntables, and aerospace applications.
The XSI141094-N bearing is a Crossed roller bearing, slewing ring standard series 14, internal teeth with an inner diameter of 984 mm , an outer diameter of 1164 mm, a width of 56 mm. It typically uses P5, P6, P0 grade precision tolerances and 50Mn,42CrMo rings, GCr15 rolling mlement. It primarily bears high radial forces and moderate axial and tilting moment loads, Its dynamic radial rated load is approximately 241000 N, its static radial rated load is approximately 710000 N. Its dynamic axial rated load is approximately 340000 N, its static axial rated load is approximately 1440000 N. lip seals on both sides type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Interchange code: XSI 14 1094 N
XSI141094-N bearings ( 984 mm x 1164 mm x 56 mm) have the advantages of The rollers are arranged in a cross pattern, resulting in minimal deformation, low rotational runout, and precise positioning, and are therefore widely used in the Industrial robots, machine tool rotary tables, medical devices, radar antennas and precision rotating equipment.

The XSI141094-N Crossed roller slewing bearings mainly consist of an inner ring, an outer ring, cross-arranged cylindrical rollers, spacers, and a sealing device. The rollers are arranged at 90° intervals within the raceway, enabling a single-row structure to withstand multi-directional loads.
The cross-arrangement of the rollers in crossed roller slewing bearings allows them to simultaneously withstand radial loads, axial loads, and overturning moments. They exhibit extremely high rigidity and a precision grade of P5 or higher. Their compact structure and easy installation significantly save installation space.
