INA YRT50 Rotary table bearing

FAG/INA BEARING

Description

INA YRT50 Rotary table bearings are ready-to-fit high precision bearings for high precision applications with combined loads. They can support radial loads and axial loads from both sides as well as tilting moments and are particularly suitable for bearing arrangements with high requirements for running accuracy, for example in rotary tables, face plates, milling heads and reversible clamps.
