Reliance Precision’s RL- and RS-series slit couplings allow greater misalignment and torsional stiffness.

Ruland Manufacturing announced it now offers Reliance Precision’s RL- and RS-series slit couplings that feature a proprietary slit pattern that has radiused as opposed to squared edges, reducing stresses that build up during misalignment conditions and torque loads. RL-series couplings have longer lengths allowing for greater parallel misalignment and increased torsional stiffness. RS-series couplings are designed to fit in compact spaces and offer parallel misalignment capabilities. Both series have a zero-backlash balanced design allowing for speeds up to 70,000 rpm. The slit couplings are available in clamp screw and set screw designs with inch, metric, and inch to metric bore sizes ranging from 1/8 inch to 3/8 inch and 1.5mm to 12mm and are RoHS3 and REACH compliant.
