Torsionally flexible pin and bush couplings and changing loads are no problem for robust, compact flexible RUPEX (R) couplings. The steel variant is especially suitable for high-speed drives. RUPEX (R) couplings are fitted by putting together the coupling halves. Fitting with low torsional backlash is simplified by the barrel-shaped geometry of the buffers. RUPEX (R) couplings require little maintenance. Only the elastomer elements, as wear parts, need be replaced and the coupled machines need not be moved to do so. RUPEX (R) couplings...

Rotor Clip Company, Inc.
Differences Between Wave Springs and Coil Springs Wave springs can simplify assembly. Many designs can locate themselves in a bore or on a shaft, reducing the need for extra retaining features. In applications that use stacked disc springs to meet load or travel requirements, a single multi-turn wave spring can often replace the entire stack. This reduces part count, simplifies handling, and lowers the chance of assembly errors. Single-turn Wave Spring. Single piece of coiled flat wire featuring an overlap, gap or patented flat ends used... (read more)Browse Washers Datasheets for Rotor Clip Company, Inc. -
