Slit couplings Reliance Precision distributed by Ruland

Cooperation agreement between Ruland and Reliance Precision for the distribution of slit couplings designed and produced in Ireland by Reliance Precision, through the e-commerce platform and the extensive worldwide distribution network of Ruland.

Reliance’s slit couplings are zero-backlash and manufactured from a single piece of aluminium with intermittent slit cuts allowing for high torque and torsional stiffness capabilities, respectively comparable to single disc couplings and stainless steel beam couplings, and also low inertia capable of speeds up to 70.000 rpm and long-life. The manufacturer’s design uses a proprietary slit pattern that has radiused as opposed to squared edges, reducing stresses that build up during misalignment conditions and torque loads. Misalignment capability is comparable to an aluminium beam coupling.

Ruland offers slit couplings in RL- and RS-series. RL-series couplings have longer lengths allowing for greater parallel misalignment capabilities and increased torsional stiffness. RS-series couplings are designed to fit in compact spaces and offer parallel misalignment capabilities, an upgrade to the single disc coupling which has comparable torque but no accommodation for parallel misalignment.

The addition of slit couplings gives Ruland a more complete zero-backlash coupling offering to complement its existing product line which includes rigid, beam, bellows, controlflex, disc, jaw, and oldham couplings. Equipment designers in industries such as packaging, scientific, semiconductor, solar, medical, and automation benefit from the wide range of sizes and performance characteristics offered by slit couplings.
