Ruland Offers MI-Series Single Beam Couplings

MARLBOROUGH, Massachusetts, Sept. 2025 – Ruland now offers MI-series single beam couplings, expanding its zero-backlash beam coupling line to include one, four and six beam styles. Single beam couplings are ideal for light-duty applications with low torque requirements such as encoders, tachometers and small analytical devices.
 
Ruland single beam couplings feature a single helical cut that allows for greater angular and axial misalignment than comparable multiple beam couplings, making them well suited for systems where precise alignment is difficult to achieve. Their compact design and low bearing loads help protect sensitive system components, extending equipment life and improving overall reliability.
 
MI-series couplings are available in clamp or set screw styles with inch, metric and inch-to-metric bore combinations ranging from 3/32 inch to 3/4 inch and 3 mm to 20 mm. They have pure metric outer diameters and lengths to better match international design standards. Hardware tests beyond DIN 912 12.9 standards ensure the coupling reaches its maximum performance capabilities.
 
The addition of single beam couplings expands Ruland’s beam coupling size range, with outer diameters now up to 50 mm. This gives designers more flexibility to select the right beam coupling style–single, four or six beam–to meet the performance, misalignment and space requirements of their application.
 
Ruland single beam couplings are carefully manufactured from high-grade 7075 aluminum bar stock sourced from North American mills in Ruland’s ISO 9001:2015 certified advanced manufacturing facility in Marlborough, Massachusetts. All Ruland couplings are RoHS3, REACH and Conflict Minerals compliant.
