The RingfederВ® locking device, part number 75 RfN 7012, is a high-quality, self-contained, frictional shaft-hub locking device designed to generate an easily adjustable and releasable mechanical connection. It is manufactured by Ringfeder in Germany and has a nominal inside dimension of 2-15/16 in. and a nominal outside dimension of 4.528 in. The RingfederВ® locking device has reduced machining costs, easy installation, assembly, and disassembly, and offers easy axial and angular adjustments and timing. It is a must-have for the fluid power industry, OEM market, wholesale and distribution market, and more. Get in touch with the seller, DYMATIC, INC. to inquire about the price and delivery. Please note that returns are not allowed on this item. Buy what you know and know what you buy! The locking assembly is based on the inclined plane or taper principle where clamping forces generated by torqued up locking screws are translated into predetermined contact pressures to create mechanical shrink-fit connections. The keyless locking device offers several advantages, including the elimination of keys, keyways, or splines and associated fitting costs, a completely tight fit around the shaft with no backlash, and being impervious to reversing, dynamic, or shock loads. This locking device is ideal for heavy-duty applications, such as in general engineering, where high torques and axial loads are required. It is commonly used for gears, rolls, cams, levers, winches, sprockets, flanges, couplings, brake drums, sheaves, flywheels, hand wheels, clutches, fan wheels, worm gears, bevel gears, helical gears, mixer shafts, crane wheels, bucket wheels, pump impellers, turbine rotors, conveyer pulleys, ship propellers, windmill propellers, rock-cutting heads, and shaft-mounted gear units.
