Standard Encoder Couplings
An encoder coupling is a type of coupling that is designed to work for precision applications while connecting various shafts together. Most encoder coupling types have small bearings that provide longevity and high performance through the use of low radial forces. Depending on the type of encoder, a variety of types of couplings can be used.
W: W couplings are ideal for light to medium duty applications. These couplings are maintenance free, and are designed for use with encoders and low torque pump applications.
MCA: The MCA couplings are made from aluminum and are designed for use with parallel misalignment. The couplings are ideal for encoders, lead screws, and moderate torque pumps.
A: The A series of encoder couplings is designed for general light to medium use. The coupling is also one of the most economical for general purpose use. The main use for the couplings is in encoder and resolver applications.
P: P encoder couplings are helical and have extra flexibility in their design. This is to reduce the bearing load and provide a flexible connection that will not break under pressure. The couplings are easy to fit into confined spaces and work well with retrofit designs.
From these options, companies can choose the type of coupling that works best with their spacing, application, budget, and space constraints. While there are also other encoder coupling options available, these four types are some of the most commonly used with encoder applications as well as other general purpose coupling applications in factories around the world.
