Designing for the defence sector means balancing strict tolerances, complex geometries, and uncompromising compliance. Small deviations can result in system failure. Delays can stall production.
That’s why engineers rely on proven suppliers with the capability to manufacture to spec — every time.

Ball screws from 16 to 80mm diameter with a range of leads - stocked lengths up to 3 metres - normally supplied with flanged nuts or cylindrical nuts. Ball screws are highly efficient due to the recirculating ball mechanism which helps the ball nuts minimise friction against the ball screw. This can also result in a long service lifetime.
Anti-corrosion ball screws are made from induction-hardened black chrome steel which make them ideal for outdoor applications, for instance. To complement this, use our anti-corrosion ball nuts. You must still be careful not to let debris enter the recirculating ball bearings - if you are concerned about this, speak to a member of our team about whether precision lead screws could be right for you.
