norelem’s ball lock pins provide engineers with reliable high shear strength

03 August 2021

norelem’s range of ball lock pins provide added reassurance to engineers where dependable high shear strength is most needed.

The ball lock pin has a practical locking mechanism designed for quick release in numerous applications. When the button is pressed, it activates the spring mechanism inside the pin which releases the ball lock by withdrawing the balls within the part. Once the button is released, the ball lock is activated again which guarantees a stable and self-securing locking function.

The component’s efficient self-locking mechanism significantly reduces set-up time, providing engineers with connections that are quick and easy to join. norelem’s ball lock pins have been designed for use in multiple applications, ranging from automation technology, robotics, electronics and processing mechanics to machine and plant construction.

norelem’s ball lock pins are available with a normal grip, T-grip or L-grip depending on the application, with diameters from 5mm to 16mm. Length sizes range from 10mm to 80mm and shearing forces from 24kN to 257kN, enabling engineers to choose the perfect fit for the job.

With higher loading potential than standard ball lock pins, norelem’s ball lock pins not only provide higher shear resistance but notable durability, ensuring the component can withstand heavy and frequent usage. This is achieved by utilising high-grade materials throughout the part’s mechanism. The initial grip is made out of thermoplastic, which is then supplemented by a stainless steel 1.4542 pin and stainless steel 1.4305 push button alongside a spring mechanism (1.4310 stainless steel) and the ball component itself (1.4125 stainless steel).

Marcus Schneck, CEO of norelem, states: “Our ball lock pins have been the leading choice for high-shear applications for several years due to the multiple benefits they have over standard ball lock pins. With the ability to fasten and join elements, workpieces and other machinery components with just the press of a button, our high-shear ball lock pins provide engineers with the reassurance of reliability and durability from the moment of installation.”

To ensure load specifications are accurate, all load values have been calculated following DIN 50141 as standard to provide engineers with the information needed to make an informed decision for the respective application.

Engineers can find the components in norelem’s definitive catalogue, THE BIG GREEN BOOK. Datasheets and CAD drawings are available online through norelem’s web shop.
