RINGFEDER GWE 5113 coupling’s hub design minimizes movement and achieves longer life cycles.

RINGFEDER released its GWE 5113 series of elastomer jaw servo-couplings, featuring a new hub design. This design eliminates radial loads and achieves uniform power transmission with an even clamp force and symmetrical arrangement of clamp and screw positions, the company says. GWE 5113 couplings transmit torques from 3 to 560Nm. The hub is slit partially through and located directly under the jaws to minimize pressure on the shaft. Units come with an elastomer spider with 98 Shore A hardness. They also come in seven sizes from 12 to 42, with diameters ranging from 4 to 56 millimeters. Units also comply with ATEX, providing maximum operational safety.
