Joyce RC-6, RC-9 and RC-12 miter gear boxes are specifically engineered for use with Joyce jacks and actuators in multiple jack systems. These smaller miter gear boxes are lubricated for life and feature aluminum housings, stainless steel shafts, and a nickel-plated pinion shaft. Standard miter boxes are 1:1 and 2:1 ratios; other ratios are available.
Ordering Information:
Miter gearboxes are important components in jack and actuator systems and it is important to select the best option based on torque requirements and rotational configuration. Refer to the list of part numbers for each miter box size.
