High misalignment capabilities

Beam couplings for encoder feedback systems

Ruland manufactures beam couplings designed specifically for encoder feedback systems. P and MW Series beam couplings offer high misalignment capabilities with low bearing loads. Machined from a single piece of aluminum or stainless steel, these couplings feature two sets of two spiral cuts for increased torsional rigidity, accuracy, and repeatability compared to single beam couplings. The multiple cut pattern accommodates angular misalignment and axial motion, but is particularly advantageous when parallel misalignment is present.

All clamp-style flexible couplings from Ruland have a balanced design. Balancing allows for operation at higher rpm with reduced vibration. Standard bore sizes are available in inch, metric, and inch to metric combinations ranging from 3/32 inch to ½ inch and 3 mm to 12 mm. Larger bore sizes, keyways, and anodizing are among the options available by special order.

P and MW Series beam couplings are part of Ruland’s complete line of clamp-style shaft collars, precision honed rigid couplings, and zero-backlash couplings including beam, bellows, disc, jaw, and oldham styles. All products are RoHS2 and Reach compliant.
