Vesconite kingpin bushings show zero wear after 4 years of harsh working conditions
Forklift steer axles typically are factory fitted with needle roller kingpin bearings. These bearings are prone to wear especially in dirty environments. Vesconite was installed on a 2.5 ton Yale forklift working in a metal recycling plant. Vesconite replaced the kingpin bushes and kingpin thrust rings. The forklift truck worked 3 shifts per day, often over broken concrete sections. The factory fitted OEM needle roller bearings lasted 2 months under these conditions. Vesconite kingpin bushes inspected after 4 years of operation were still in perfect condition.
A sawmill forklift has to operate under dusty conditions and over rough terrain. These unfavourable conditions coupled with poor lubrication resulted in the original bearings on the mast breaking down approximately every six months.
