New gear technology! Dual gear change kit gives the best of two worlds. The 675:1 ratio is for extra heavy-duty machining and supreme accuracy, while the 90:1 ratio is for medium duty rotation and indexing 7.5 times faster, up to 8.3 rpm.
This gear kit fits our rotary tables that are designed for 675:1 gearbox. Includes MRT6-57-675, MRT8-57-675, MRT10-57-675, and MRT12-57-675, and same size HV rotary tables. It does not fit any other gear ratio rotary tables.
Only Excitron offers a dual gear ratio rotary table, now you do not need to buy two different rotary tables--saves you money.
Pictures show final assembly for the 675:1 ratio and the 90:1 ratio. This option does not include the stepper motor/controller and worm gear stem. This option only includes the extra steel plates and hardware so you can have both gear ratios on our heavy-duty rotary tables. You should order this option at the same time you order your rotary table, although you can order later without any down-side.
With this kit, it only takes 5 minutes to change over from 675:1 ratio to 90:1 ratio and vice-versa.
