YRT80 Turntable Bearing,Rotary Table Bearing, High Precision Machine Tool
YRT80 rotary table bearing is a kind of bearing fixed by a bidirectional thrust bearing and a centripetal-guided bearing. They can support radial loads, axial loads from both directions and tilting moments free from clearance and are particularly suitable for bearing arrangements with high requirements for running accuracy,like rotary tables, millings heads and reversible clamps chucks , milling heads, measuring instruments , test equipment as well as rotary turntable.
