All type of workshops benefit from using Expander System

I replace pins in new equipment Using Expander System in new equipment lowers the total cost of operation. Machines with less wear last longer and have a higher resale value.

I work with line boring When lug wear is excessive and it is not possible to re-torque after installation, a fast & permanent solution is possible. Simply make a rough cut to make the hole round again and fit Expander System with oversized sleeves.

I have no line boring equipment Play needed to mount a straight pin is the main reason for wear, which occurs as soon as the machine is used. Expander System solves lug wear issues without using line boring equipment – ultimately making repairs safer.

I offer field maintenance to customers Expander System is an optimal field repair solution. Reducing downtime brings huge savings for your customers. No hot works are needed, increasing operator safety. The on-site operator can do the retorquing – no special tools needed.
