MKA Miter Gear Boxes

Joyce MKA miter gear boxes are specifically engineered for use with Joyce jacks and actuators in multiple jack systems. These heavy-duty miter gearboxes are rated for 3,000 inch-pounds torque @ 100 RPM. They feature ductile housings, and steel input and pinion shafts. Standard miter boxes are 1:1 ratio, but other ratios are available. MKA gear box housings feature flanged base mounts which differ from the RC series gear boxes.

Ordering Information:

Miter gear boxes are important components in jack and actuator systems and it is important to select the best option based on torque requirements and rotational configuration. Contact with your questions and allow us to help you specify the compatible components for a complete system. Otherwise refer to the list of part numbers for each miter box size.
