Ruland Shaft Couplings

Disc Couplings

Ruland disc couplings are an assembly of two anodized aluminum hubs and multiple thin, flat stainless steel disc springs.

Single and double disc styles are available with bore sizes ranging from 1/8” to 1 1/4” in the inch series and 3mm to 30mm in the metric series. The double disc styles include a center spacer offered in either anodized aluminum or insulating acetal for electrical isolation.

The discs between the hubs allow for a substantial amount of angular and parallel misalignment between shafts, while remaining rigid under high torque loads. Disc couplings are high performance motion control couplings ideal for high speed applications of up to 10,000 rpm. 

All disc couplings now feature a black anodized finish.
