YRT120 Rotary table bearing for CNC machine

Product Description
Rotary table bearing YRT120, 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.
