When speed matters: Large ball screw saves automotive manufacturer from costly downtime

When a large ball screw, which formed part of a well-known motor manufacturer’s wheel and tyre assembly machine on Line 2, began to make ominous noises, its engineers were quick to inspect it.

A fundamentally important part of the production line, the wheel and tyre assembly machine is used to assemble tyres onto wheel rims. If the ball

The decision to replace it was therefore
made swiftly. Unfortunately, the ball screw, which measured 1,165mm in length, was a non-stock item and therefore either had to be ordered and imported from
overseas, or be made bespoke. The former would take too long and the latter, the company expected, would be expensive.
