Product Info

Spring plugs and cotter pins (also called locking pin) are locking elements for different applications. They are often used for bolt connections as a simple and releasable locking element and are used to secure the axial force. The axial force is not the main load on the joint. The locking element is primarily used to hold the assembly together. The axial force is therefore often a smaller by several orders of magnitude than the radial force on the bolt. This article discusses the locking principles for bolt joints with locking pins, along with application examples of the various locking elements in mechanical engineering, and based on what criteria these elements can be selected.

What makes a linear guide profile rail guide the first choice for precise and resilient motion control? In our blog, you will learn all about the design, the different versions, dimensional tolerances and the key parameters, such as running parallelism, preload and axial play. We show how these features work together perfectly to ensure the highest precision and durability – and how you can best match these components to your needs.
