18-1500-00 Bore 1317 Mm, Standard Double Row Crossed Rollers Slewing Rings Without Gear With Spacers
The 18-1500-00 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 18-1500-00 bearing is a Standard double row crossed rollers slewing rings without gear with spacers with an inner diameter of 1317 mm , an outer diameter of 1688 mm, a width of 150 mm. It typically uses P0, P6, P5 grade precision tolerances and XC45 or 42CrMo4 rings, GCr15 rolling mlement. It primarily bears axial, radial and tilting moment loads, Double sealed type, NBR (Nitrile Butadiene Rubber). together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
18-1500-00 bearings ( 1317 mm x 1688 mm x 150 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 18-1500-00 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.
