Conveyors Rotary Kilns Ball Mills Fans CentrifugesPinflexA robust general purpose pin/buffer coupling, providing reliable fail safe transmission of torque and misalignment capability. Pumps Compressors ConveyorsCrown PinAn 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.

6 Conveyors Washers Pumps Screens Cranes General Industrial ApplicationsSpider CouplingsRelatively low power but highly flexible coupling with halfbodies in either cast iron or bronze, making suitable for use in the food or chemical/pharmaceutical industries. Pumps Mixers Lube SystemsGearflexHeavy duty all metal Couplings giving maximum power capacity within minimum space envelope and excellent misalignment capacity. Steelworks Quarries MiningPage 05 Typical general purpose, fail safe, torsionally flexible coupling offering the option of either urethane or reinforced rubber disc. Pumps Compressors Conveyors MixersSpiderflexA medium powered, torsionally flexible coupling, combining shock absorbing and misalignment. Used in the widest range of industries and range of highly flexible Couplings offering excellent misalignment capacity and suitable to absorb both shock loads and vibrations. Pumps Compressors Diesel engines Roller tablesRenoldflexRenoldflex is a torsionally rigid coupling (TRC) that utilises a stainless steel spring disc pack to provide a positive backlash free drive.
