Gendron spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Gendron spindles and motor spindles. Gendron is a French brand of cylindrical grinders (RU 28 series) still widely found in French workshops.
Gendron, French cylindrical grinders
TLDR: Gendron is a French brand of external and internal cylindrical grinders. The RU 28 series comes in several grinding lengths (for example RU 28-100 and RU 28-150). These machines have often been rebuilt (retrofitted).
Gendron grinders are still running in many workshops, and specialist shops offer complete rebuilds of them, which confirms their presence on the market. Many have been retrofitted: new control, new electrics, but the original spindle stays in place and still determines the machine's accuracy.
Beware of the "RU" name clash. The designation "RU 28-100" also exists at the Italian manufacturer AZ. No link between the two brands has been confirmed.
The RU 28 series: a 300 mm wheel
TLDR: A Gendron RU 28-100 is listed with a 1,000 mm grinding length, a 280 mm maximum diameter and a 300 mm wheel. Spindle power and speed are not specified.
For example, an RU 28-100 is listed with a 1,000 mm grinding length, a 280 mm maximum diameter, a 155 mm centre height, a 1,660 × 150 mm table and a 300 mm wheel. The year, power and speed of the Gendron spindle are not given in the listing: we confirm them in our quote, from the nameplate.
