Ball locks now available in stainless steel for improved durability

08 April 2021

Standard parts and components supplier, WDS Components Ltd, has released a stainless steel version of its ball lock mechanism.

The new product line provides extra durability and rust-free use for the accurate locating and locking of fixture plates and subplates to machines. 

The ball lock mounting system ensures repeatable positioning, reducing set-up time and making secure installation of plates to machinery both fast and simple. Accuracy of positioning means the installer doesn’t have to make an extended check of fitting, reducing overall installation time. The advantage of the ball lock compared to using dowel pins is a result of its location and pull-down fastening mechanism, providing greater accuracy and security. 

The device consists of a locating shank as well as liner and receiver bushings. The receiver bushings are installed into the machine or subplate with the liner bushing inserted into the fixture plate. The locating shank is then inserted through the liner and into the receiver where tightening the shank’s grub screw establishes the required holding force.

Ball locks are regularly specified by end user fixture designers aiming to improve or secure OEM-supplied machinery, as well as machine builders using the fastening devices at the source. 

The advantage of the new stainless steel ball lock mechanisms is their resistance to corrosion, even in aggressive environments. 

Stainless steel ball lock shanks and bushes will remain rust-free over prolonged use with corrosive media, ensuring longer machine life and improved maintenance procedures.

The ball lock shanks, which are removed and act as installation tools, are available in 12 sizes, while the liner bushes are available in 33 sizes. Reverse-mount bushes are also available as well as a version with recesses, which can be bolted to the plates. The ball lock shank also has an optional repair kit available, consisting of replacement bearings and an O-ring, which helps keep down maintenance costs.

Full product specifications, including CAD drawings and non-specialist 3D images, can be found on The stainless steel ball lock mechanisms are available from stock and can be shipped on a same-day basis for fast delivery.
