Product Description


Crop sprayer rocker arm Bushings | Metal-Polymer Plain Bearings

Application requirements

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.
