Structural Characteristics
Rotary table bearing YRT120, the structure includes a set of radial rollers, two groups of thrust roller, cages, an outer ring, an L shaped inner ring, and a second inner ring. The outside and inside rings have mounting holes, also the bearing will be preloaded before out of the factory. This design not only simplified the structure of parts but much more reduced the requirements of installations and working time.
Applications
Turntable bearing YRT120 is widely used in occasions of high precision, high rigidity, but low joint load and short-time operations. Such as Indexing table and Rotary milling head etc.
