Retained Clamping Elements

Elesa offers a range of products and straightforward solutions designed to keep clamping elements securely attached to machinery, ensuring compliance with Machinery Directive 2006/42/EC. This European regulation governs the manufacture, market placement, and commissioning of machines, setting out essential safety and performance requirements. Beyond the serious risk to worker safety, the loss of machine components can lead to production delays, machine downtime, and increased maintenance costs. For designers and mechanical engineers, ensuring all machine components - including retained clamping elements - meet the Machinery Directive is a fundamental design consideration.

A common application is the use of threaded inserts with locking mechanisms. They ensure that knobs remain securely in place, even under vibrations or mechanical stress, thanks to the non-threaded section.
