GGB's Metal-Polymer Bearing Solution for Crop Sprayer Boom Arms
Bearing Application Requirements
Self-propelled and trailed crop sprayers apply controlled doses dry and liquid herbicides, pesticides and fertilizers to agricultural crops. To enhance their maneuverability, self-propelled crop sprayers are available with four-wheel direction and drive.
In addition to being equipped with an independent dual strut and air spring suspension, each wheel is steered via a kingpin assembly fitted with antifriction plain bearings.
GGB Agricultural Plain Bearing Solution
Optimal performance in this high load, low speed application is obtained by mounting DX® steel-backed bearings with a porous bronze sinter interlayer and pin indented acetal sliding layer.
The benefits gained from using DX® grease-lubricated plain bearings are:
- Indented surface layer serves as a grease reservoir for extended lubrication intervals
- Optimal retention and distribution of lubricant over the bearing sliding layer for reduced friction and wear and extended service life
- Central lubrication hole to facilitate regreasing and expel contaminants from the bearing
