Low - Maintenance Bronze Sleeve Bushings For Field Crop sprayers Steering Kingpin
OEM MAFACTURER Plain bearings - lubrication holes, grooves and pockets - dimensions, types, designation and their application to bearing bushes.
In addition to being equipped with a separate double leg and air spring suspension, each wheel is steered through a kingpin assembly with antifriction sliding bearings.
 

Agricultural bearing solutions

In this high-load, low-speed application, the best performance is achieved by mounting the POM with a porous bronze sintered intermediate layer and a pinched acetal sliding layer.
 
 
The best maintenance and distribution of lubricant on the bearing sliding layer can reduce friction and wear and prolong the service life

Central lubrication hole, convenient for re-lubrication of the bearing discharge pollutants

Crop sprayer steering kingpin | Metal-Polymer Plain Bearings & Sleeve Bushes

Applications require self-propelled and trailing crop sprayers to apply controlled doses of dry, liquid herbicides, pesticides and fertilizers to crops.In order to improve the maneuverability, the self-propelled crop sprayer has four wheel direction and driving function.Metal-Polymer Plain Bearings is used steel-backing as its structure, sintered porous bronze as its interlayer, surface inlaid the modified POM. Suitable for marginally lubricated and dry operation on the conditions of lubrication indents grease. It has been widely applied to metallurgical machinery, Mine machinery, water conservancy machinery, vapor locomotive, building machinery, agriculture machinery, steel rolling industry etc.
