Low-maintenance bronze sleeve bushings designed for field crop sprayers' steering kingpin are a reliable and durable solution for agricultural machinery. These bushings are specifically engineered to withstand the rigors of outdoor environments and frequent use, ensuring smooth and efficient steering operation. The bronze material offers excellent wear resistance and corrosion resistance, extending the lifespan of the bushings and reducing the need for frequent maintenance. Additionally, the sleeve design provides a secure fit and minimizes friction, further enhancing performance and reliability. Overall, these low-maintenance bronze sleeve bushings are an ideal choice for field crop sprayers' steering kingpin, enabling efficient and reliable steering performance in agricultural applications.
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
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.
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.

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.
Agricultural bearings - advantages
Benefits of using POM grease lubricated sliding bearings are:
The reduced surface layer is used as a grease reservoir to extend
the lubrication interval
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
