Beam Couplings for Encoder Feedback Systems
Ruland manufactures four beam couplings designed specifically for encoder feedback systems. These couplings offer high misalignment capabilities with low bearing loads and are torsionally stiffer than single beam couplings, allowing for greater accuracy and repeatability.
Ruland are machined from a single piece of aluminum or stainless steel and feature multiple spiral cuts. This proprietary beam pattern provides higher torque capabilities and greatly reduces wind-up when compared to competitor single or four beam couplings. The two sets of beams allow the coupling to accommodate all types of misalignment: angular, parallel, axial motion, and complex. Ruland is also the only manufacturer to offer clamp style beam couplings with a balanced design.
Ruland four beam couplings come in two styles, and , for choices in size and performance. Both series are manufactured in aluminum for added flexibility and low inertia or stainless steel for higher torque. Bore sizes are available in inch, metric, and inch-to-metric combinations ranging from 3/32” to 1/2” and 3mm to 12mm.
Beam couplings are part of Ruland’s complete zero-backlash coupling line, also including bellows, disc, jaw, oldham, slit, controlflex, and rigid. Beam couplings are carefully manufactured from meticulously selected bar stock in our advanced manufacturing facility in Marlborough, Massachusetts, under strict control using proprietary processes. 3-D CAD files, full product specifications, and additional technical information are all available on ruland.com.
