TJR HR Hydraulic Brake Series
The HR-Series is TJR’s hydraulic brake series of standard 4th axis rotary tables that is offered in multiple sizes. The sizes range from 210mm (8.26”) to 800mm (31.49”) face plate diameter. The HR series offers a Big Bore through hole design that delivers high rigidity and offers a larger work space for piece set up with fixtures and can be adjusted by using a mandrel sleeve.
These units are capable of being mounted in both the vertical and horizontal position. The HR series also offer a reduced sheet metal design that is suitable for tight vertical or horizontal applications.
The HR series is manufactured with a large radial-axial preloaded bearing system for high rigidity that can perform heavy cutting. The HR-Series uses a dual lead worm shaft and worm gear to ensure long term indexing accuracy in both directions.
