With a higher load capacity than jaw couplings and maintenance-free operation, FRCcouplings are designed as a general purpose coupling. They are able to cushion moderateshock loads, dampen low levels of vibration and accommodate incidental misalignment.FRC couplings offer a range of hubs and elements to select, to meet the demand for lowcost, general purpose flexible coupling. FRC couplings are phosphate coated forimproved corrosion resistance and available with fire-resistant and anti-static elements(F.R.A.S.) FRC couplings are available with a pilot bore, finished bore or tapered bushing(face or hub) to make installation quick and simple.Fully machined outside surfaces allowalignment with a simple straight edge. Shaft connections are "fail safe" due to their interlocking jaw design.
