Automobile Chassis 52W/Mk Self Lubricating Bronze Bushings
Bronze bushing for combine harvesters. Dimention in MM.Aftermarket spare parts.tri-layer low maintanence plain bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after rolling process completed. Lubrication indents are stamped into this layer.POM BUSHES has good physical & mechanical properties, also has certainly chemical properties. This material has good machining performance if required.
1. Self-lub. Layer POM 0.3-0.5mm. After rolling process completed, POM are filled in intersice of bronze layer, lubrication indents are stamped, which are full of oil grease, which will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2. Porous bronze layer; The layer provides bonded strength of self-lub. Layer.
3. Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer.
Destination
Ensuring the optimal level of friction between the elements of the node during its operation.
This spare part is used for replacing worn out or damaged parts during repairs.
Properties
Bronze product in the form of a piece of a hollow cylinder with internal perforation and a slot on the side surface.
Straight bushings
Flange bushings
Thrust washer
strip
Non-standard products are also avalidable

Application field | automobile chassis, Forging Machine, Metallurgical machinery, Mining machinery, Water conservancy machinery, Steel rolling industry.etc |
Material | Steel base+ Bronze powder+ POM |
Application
The product can be used under high load with low speed, rotation, oscillation and can also be applied in an environment without liquid lubricant which frequently switches with the load.
The part can operate without oil and will have a long service life if it gives oil.
The POM layer can be machined during installation, which benefits the coupling.
BM-2 bushing products are now mainly used in metallurgy machinery, mining industry, irrigation machinery, agricultural machinery, etc.
