YRT rotary table bearings consist of a thrust/radial housing washer, a thrust/radial shaft washer, a thrust washer, two axial needle roller and cage assemblies and a group of radial cylindrical rollers. Housing washer and shaft washer have equally spaced fitting bolt.
These bearings have high axial and radial load, and high tilting rigidity and high precision.
Applications: mainly used on the machine tools, high precision machinery of the totary table or sub-set, and chuck, measuring instruments and test enquipment and rotary table.
Outer Diameters: range from 126 mm to 1490 mm
1) including retaining screws and threaded extraction holes
2) note install screws
3) bearing frictional torque must be tested under speed 5r/min, the startup frictional torque should be around 2-2.5 times of listed data.
