The AR-Series is TJR’s standard 4th axis rotary table that is offered in multiple sizes. The models featured here are for Rear (Back) motor mounting and range from 125mm (4.92”) to 250mm (9.84”) face plate diameter. They are capable of being used as a full 4th axis that is integrated into the CNC machine control or as an indexer with the use of TJR’s SAC (Single Axis Controller).
These units are capable of being mounted in both the vertical and horizontal position. In addition they are also offered Right Handed and Left Handed motor configuration with a powerful pneumatic braking system.
The AR series is manufactured with a radial-axial preloaded bearing system for high rigidity that can perform light or heavy cutting. The AR-Series uses a dual lead worm shaft and worm gear to ensure long term indexing accuracy in both directions.
