Due to harsh conditions, the standard OEM Spherical Bearing located on the A-Frame assemblies in CAT 777 & 785 Haul Trucks regularly experience premature failures due to cracking and eventual splitting of the Outer Race. The Geographe A-Frame Colleted Pin Assembly (CPA) has a modified working arrangement allowing for a thicker outer shell, offering increased strength while maintaining complete interchangeability with the OEM. Optimise your Caterpillar Haul Truck fleet with the Geographe Enhanced Performance™ A-Frame CPA!
