Linkage kits are available for the mechanical connection from the actuator crank arm to the load lever arm. Beck’s linkage kits help move your control by eliminating slop in your linkage connection.

When a linkage connection is properly sized, designed, and implemented it will help ensure that you have a successful, long-lasting installation. Beck Engineers are available to assist you with designing your linkage and specifying the appropriate linkage kit through our free Link-Assist service. Beck offers two different styles of linkage kits and hex linkage kits.

Beck provides a complementary service called Link-Assist to support the setup and installation of our linkage connected actuator products. Link-Assist is an exclusive linkage program that provides Beck Engineers the ability to design an optimal linkage configuration based on your application specific constraints. Beck can supply you with the recommended linkage length, crank/lever arm start angles, and crank/lever arm radii. This information is available in a date-stamped comprehensive report that also provides the delivered torque and force profiles throughout travel.

Link-Assist reports can be generated for new installations or to ensure optimal setup of existing installations. Download a sample of a completed Link-Assist Report by clicking the to the right.

Rod End Details and Dimension Chart

Rod ends with bearings are used to provide long term reliability, virtually eliminate binding and wear, and provide tight control of the driven load. These rod ends allow for some lateral misalignment between the drive shaft and driven load which simplifies installation.
