YRT180High Precision Rotary Table Bearing180*280*43mmCNC machine tool rotary table bearings
YRT180bearing 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 roller . Housing
washer and shaft washer have equally spaced fitting bolt. This kind
of bearingsYRT180have high axial load and radial load ,and high tilting rigidity and
high precision.YRT180can be used to the machine tool and other high precision machinery
of the rotary table or sub-set, and also can be used for chuck,
measuring instruments and test equipment and rotary table

Design & Installation forYRT180:
Structure with the requirements shown in Figure 1
Retaining screws secure the bearing components during transport.
For installing the bearing easier, the screws should be loosened
before fitting, and secured again or replaced by positioning screws
The L-section ring can be fitted with unsupported or supported
a) Without supported ring, the bearing type isYRT180.
b) With supported ring, the bearing type isYRT180-VSP.And the whole surface of L-section should be supported.
Mounting forces must only be applied to theYRT180bearing ring to be fitted, never through the rolling elements.
Tighten the fixing screws in crosswise using a torque wrench (shown
in figure 2).
Don’t separate or interchanged bearing components during fitting
Starting friction torque can be 3 to 3.5 times as high as the value
of friction torque in the dimension tables.
