Passenger, locomotive and wagon bogies can contain a number of resilient elements such as bump-stops, bolster springs, spherical & plain bushes, elements for steerable bogies and shock-absorber mounts. Mackay has designed and manufactured these resilient elements for service life improvements over OEM components.

A large number of our projects have significantly redesigned components for service life improvements through the course of our many years of experience as Australia's top bogie components supplier.



Mackay has designed and manufactured both original equipment and replacement locomotive rolling stock primary suspension elements.


Re-engineering has been undertaken to allow for an increase in locomotive weight during upgrade whilst maintaining unchanged fitment. Mackay provides re-engineered elements to address in-service lifetime issues with original equipment components.
