88-0464-60 Bore 395 Mm, Precision Roller Slewing Rings (Rotary Table) Without Gear With Cage
The 88-0464-60 Rotary table bearings are suitable for high-precision, high-rigidity rotary applications. Classic applications include CNC machine tool rotary tables and indexing tables, industrial robot joints, military radar antennas, aerospace measurement equipment, astronomical telescopes, and medical devices.
The 88-0464-60 bearing is a precision roller slewing rings (Rotary Table) without gear with cage with an inner diameter of 395 mm , an outer diameter of 525 mm, a width of 65 mm. It typically uses P6, P5, P4 grade precision tolerances and 100Cr6 rings, GCr15 rolling mlement. It primarily bears axial, radial and tilting moment loads, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
88-0464-60 bearings ( 395 mm x 525 mm x 65 mm) have the advantages of It can withstand axial, radial and overturning moments simultaneously, has a compact structure, is easy to install, and is suitable for heavy-duty rotation, and are therefore widely used in the high-end CNC machine tools, robots, indexing tables and rotary tables.

The 88-0464-60 Rotary table bearings are precision bearings with a thrust-radial combined structure. They mainly consist of a housing ring, a shaft ring, two rows of axial cylindrical roller cage assemblies, and one row of radial cylindrical roller cage assemblies. The housing ring and shaft ring are evenly distributed with mounting screw holes for easy direct fixing.
The advantages of rotary table bearing design are that it can simultaneously withstand radial loads, bidirectional axial loads and overturning moments. The negative clearance preload design ensures extremely high rigidity and rotational accuracy. Moreover, the compact structure greatly simplifies rotary table design and reduces installation and maintenance costs.
