Combine harvester axle and king pin bushing challenges solved with Vesconite Hilube

Metalfor, a leading Argentinian equipment manufacturer, has used Vesconite Hilube bushings for its Class 7 combine harvesters since 2010.

Vesconite Hilube wear-resistant, self-lubricating bearing material is used for king pin bushings on the steering system and axle pivot bushings on the back axle.

“We switched from bronze to Vesconite Hilube in 2010 since these are such important applications,” a design engineer stated when Vesconite Bearings visited the company in 2022.

Metalfor applies grease to the bushings upon installation to increase wear life and it also installs a grease zerk for greasing if desired.

However, Vesconite is internally lubricated, which is advantageous if a farmer does not grease bushings for long periods.
