Factory Price High Quality Rotary Table Bearing YRT150 For NC Rotary Table

YRT 150 turntable bearing is a type of rotating mechanism with outer ring rotation and inner ring support. It is mainly divided into three series: YRT type, YRTS type and YRTM type. These three series of bearings have the same installation size, internal structure difference, and similar performance. YRT series bearings are composed of three rows of rollers. Two rows of axial rollers ensure stable axial load-bearing capacity. One row of radial rollers ensures that the bearings can withstand radial force and overturning moment and are suitable for axially-carrying rotary machines.

Structural Characteristics

 

Rotary table bearing YRT150, the structure includes a set of radial rollers, two groups of thrust roller, cages,  an outer ring, a L shaped inner ring and second inner ring. The outside and inside rings have mounting holes, also the bearing will be preloaded before out of factory. This design not only simplified the structure of parts, but much more reduced the requirements of installations and  working time.

 

Applications

•Precision machine tools

•precision Turntable, NC rotary table

•Rotation part of Machine tools

•Inspection instrument,Medical equipment

•Indexing plate of other precision machines etc

 

Design & Installation 
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 after fitting.
The L-section ring can be fitted with unsupported or supported ring.
a) Without supported ring, the bearing type is YRT.
b) With supported ring, the bearing type is YRTVSP.And the whole surface of L-section should be supported.
Mounting forces must only be applied to the bearing ring to be fitted, never through the rolling elements.
Dont separate or interchanged bearing components during fitting and dismantling. 
Starting friction torque can be 3 to 3.5 times as high as the value of friction torque in the dimension tables.

 

Our Advantages
