Turntable Bearing
Crossed roller bearing incorporates two rings and is designed with compact construction, light weight, high precision, and small assembling clearance. The rollers are crossed one by one, enabling the slewing bearing to accommodate high axial, radial and tilting moment loads.Gear teeth on the outer ring,inner ring or withour gear teeth,bearing rings with through holes or threaded holes for fixing screws.
Cross roller bearing is suitable for hoisting equipment and other engineering machinery.The famous types are XA,XI,XU,SX,XSU,XV series.
Products Class of This Type
YRT Turntable bearings (rotary table bearings) are axial and radial combined cylindrical roller bearings, including two thrust needle roller bearings and a radial cylindrical roller bearing with the combination of axial and radial p reload, For the convenience of transportation and fixing, two or three symmetrical screws are fastened to the two rings in order to prevent rollers and rings generating collisions which influence bearing accuracy.
S:Due to their high limiting speeds and very low, uniform frictional torque across the whole speed range, these bearings are particularly suitable for combination with torque motors.
M:Axial/radial bearing YRTM: Bearing of YRTM series correspond in the double direction thrust cylindrical roller combined bearing YRT ,but are additionally fitted with a steel ruler, to control and adjust the double direction thrust cylindrical roller bearing rotation accuracy, and guarantee the machine high precision operation.
ZKLDF: are low-friction, high accuracy for very high speeds, high axial and radial loads and high demands on tilting rigidity. These bearings are particularly suitable for precision applications involving combined loads. Their preferred areas of use are bearing arrangements in rotary tables and honing heads as well as measurement and testing equipment.
