RTC080 Bore 80 Mm, Axial/radial Cylindrical Roller Bearing, Double Direction, RTC
The RTC080 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 RTC080 bearing is a Axial/radial cylindrical roller bearing, double direction, RTC with an inner diameter of 80 mm , an outer diameter of 146 mm, a width of 35 mm. 50Mn,42CrMo rings, Its dynamic radial rated load is approximately 42500 N, its static radial rated load is approximately 100000 N. Its dynamic axial rated load is approximately 56000 N, its static axial rated load is approximately 255000 N. Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
RTC080 bearings ( 80 mm x 146 mm x 35 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.

| Additional information |
The RTC080 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.
