Crop sprayer rocker arm metal polymer plain bearings, cast from bronze, are a robust and durable choice for agricultural machinery. These bushings offer excellent wear resistance and low friction, ensuring smooth and reliable operation of the rocker arm in crop sprayers. The combination of metal and polymer materials provides both strength and corrosion resistance, making these bearings suitable for use in outdoor environments. Additionally, the cast bronze construction ensures a tight fit and long-lasting performance. Overall, these metal polymer plain bearings with cast bronze bushings are an ideal solution for ensuring efficient and reliable operation of crop sprayer rocker arms.
Self-propelled and trailing crop sprayers incorporate sliding bearings into the pivot joints of the arms for folding and unfolding.
This demanding application requires sliding bearings that work in a variety of severe weather conditions and resist corrosion from chemical exposure during controlled doses of dry or liquid herbicides, pesticides and fertilizers.
In addition to its excellent corrosion resistance, the
maintenance-free self-lubricating bushing has the following
additional advantages:
Environmentally friendly drying operation can eliminate soil
pollution in oil pollution
Reduce equipment costs without the need for lubrication systems,
conduits, hoses, joints/parts and expensive oil-retaining seals
Reduced cost of ownership, maintenance-free operation and extended
service life
Higher productivity, bearing replacement maintenance and
replacement without downtime.
Lightweight, compact, robust bearing design with excellent shock
resistance, shaft misalignment and wear.
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.
