Metalfor, a leading Argentinian equipment manufacturer, has used Vesconite bushings in sprayer boom pivots on self-propelled crop sprayers since 2007 … and with great success.
Metalfor’s crop-sprayer bushings have to face a variety of challenging operating conditions. Whilst spraying, crop sprayers are continuously exposed to water and a mixture of chemicals. After use, a sprayer is also typically cleaned with high-pressure water to blast the chemicals away. The spray chemicals and pressure washing also typically flush grease out of the pivot points.
Vesconite has proven to be the solution to these operating conditions. Unlike bronze, it resists a wide variety of chemicals. Vesconite also does not corrode because it is a polymer, which is an advantage because of the chemicals sprayers encounter.
Moreover, Vesconite is highly valued for its self-lubricating properties; while Metalfor provides for the greasing of bearings where a farmer desires this, the bushings’ self-lubricating properties are an extra benefit when greasing is absent.
These Vesconite properties make the bushing material suitable for the harsh conditions encountered by agricultural sprayers, Metalfor says.
