Ringfeder releases GWE 5117 servo-coupling for hollow shaft connections
RINGFEDER has recently released its GWE 5117 series of elastomer jaw servo-couplings, featuring a new hub design. With its partially slit hub located directly under the jaws and two screw clamps, this model eliminates radial loads on the shaft and achieves uniform power transmission. This hub design also prevents premature wear and system failure. Designed […]
How to handle elastomeric coupling creep
In engineering, one of the more common questions ABB gets on the Raptor coupling deals with the twisting of the element. Many users incorrectly assume this is a sign of failure. This phenomenon is common to any elastomeric coupling and is the result of a process called creep. Here, we take a look at several […]
