All type of workshops benefit from using Expander System

I replace pins in new equipment The use of Expander System in new equipment lowers the total cost of operation. A machine with less wear will also have a higher second-hand value.

I work with line boring Sometimes the lug repair is made too late and the wear is too big, or it is not possible to re-torque after installation. A fast and permanent repair is to make a rough cut to make the hole round again and fit Expander System with oversized sleeves.

I have no line boring equipment The play needed to mount the traditional straight pin is the major reason for the wear, and the wear will start again as soon as the operator uses the machine. Expander System solves the issue of lug wear without the use of line boring equipment and makes repair work safer.

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