First-fit Design for Original Equipment Manufacturers (OEM)
Personalization in every pin - we design and manufacture to your exact tolerances and requirements, eliminating a weak link in the machine so it can perform for longer, exactly as it was built to.

"Whatever your machine, industry or application, we will create the perfect pivot pin for you"
HIGH PERFORMANCE
Power your machine to perform like it was built to. The sleeves expansion in the bore eliminates play and redistributes the load. Prevent lug wear from the first installation, minimize unwanted movement and reduce the overall bearing/pivot wear.
FOR ANY REQUIREMENTS
With no one-size-fits-all approach to high performance parts, we engineer (and re-engineer) tailored solutions to overcome heavy industry's pin problems. As the first-to-market with more than 40 years of experience, we make it easy to build new machines with world-class pins. Best-in-class test centers validate the performance of Expander products under real world conditions.
VALUE ADDING
Use Expander System to build value-added models with a lower total lifecycle cost. Switching to first-fit streamlines your assembly process and lowers the total build cost. Listing Expander as an aftermarket wear part gives your customers choice, and you an additional revenue stream. Plus, a longer lasting pin system improves the sustainability profile of your machines.
