Motion Control Couplings with Inch to Metric Bores

Motion systems often utilize a servo or stepper motor with metric shafting driving a ball screw, lead screw, or encoder with inch shafting. Matching application parameters to a motion control coupling can be a challenging task which becomes more difficult when inch to metric bore combinations are required. Ruland now stocks a full range of motion control couplings with inch to metric bores including beam, bellows, curved jaw, disc, and oldham types. Motion control couplings from Ruland are zero-backlash for accuracy of motion and are manufactured in our Marlborough, MA factory.

Choosing the correct servo coupling can be a difficult process that involves many performance factors including: shaft misalignment, RPM, space restrictions, torque, and others. Motion control couplings from Ruland are available in a wide variety of styles, sizes, and materials to match application requirements critical to system performance. For more information about the differences between each coupling see below.

• Full range of zero-backlash couplings to match different application requirements.
• Precision honed bores on straight bore rigid couplings for superior fit and torque transmission and alignment.
• Proprietary Nypatch® coating on rigid coupling hardware resists vibration and maintains holding power.
• Flexible servo couplings have a balanced design leading to better performance, reduced vibration, and increased speed capabilities.
• Ruland has designed flexible couplings to offer better torque and stiffness while still accommodating misalignment.
• Raw materials are sourced from select North American mills to ensure product consistency.
• All servo couplings are carefully made in our Marlborough, Massachusetts USA factory with large stocks for same day shipment.
• Hardware is carefully selected and tested to ensure maximum torque capabilities.
