Superior Coupling Technology

Renold Couplings Renold have been manufacturing exible and rigid couplings, sprag and air clutches for over 50 years. The Renold Couplings factories are based in three global locations - Cardiff, Wales; Halifax, England and Westeld, New York, USA. Renold Clutches and Couplings, Cardiff, Wales Renold Hi-Tec Couplings, Halifax, England Renold Ajax, Westeld, New York, USA. In 1991 the company moved to a purposebuilt factory in Wentloog, Cardiff, in which state-of-the-art machining and inspection facilities are to be found, all supporting a high level of personal customer care. The Halifax factory...

Typical Applications Hydrastart A uid coupling suitable for soft starting high inertia machinery with reduced current demand, controlled acceleration and torque with drive overload protection. • Conveyors • Rotary Kilns • Ball Mills Pinex A robust general purpose pin/buffer coupling, providing reliable fail safe transmission of torque and misalignment capability. • Pumps • Compressors • Conveyors Crown Pin An established pin/buffer coupling offering extended power capacity where the demand for long life and simplicity of construction make it suitable for working in arduous conditions. • Conveyors...

Typical Applications Discex A general purpose, fail safe, torsionally exible coupling offering the option of either urethane or reinforced rubber disc. • Pumps Spiderex A medium powered, torsionally exible coupling, combining shock absorbing and misalignment. Used in the widest range of industries and applications. Tyreex A range of highly exible couplings offering excellent misalignment capacity and suitable to absorb both shock loads and vibrations. • Pumps • Diesel engines • Roller tables Renoldex Renoldex is a torsionally rigid coupling (TRC) that utilises a stainless steel spring disc pack...

Coupling Selection Guide Parallel offset Torsional exibility Flexible Couplings should be used to accommodate any combination of misalignment conditions ƒ described below. ƒ At installation all couplings should be aligned as near to Ø perfect as possible. Ø 1. Angular Angular misalignment is present when the shaft axes are inclined one to the other. Its magnitude can be measured at the coupling faces. 2. Parallel Offset Parallel misalignment is present when the axes of the driving and driven shafts are parallel but laterally displaced. 3. End oat (axial) End oat is the ability to accommodate...
