Materials commonly used for motor bearings include the following main categories? : ?

Bearing alloy? : Bearing alloys, also known as white alloys, are mainly composed of alloys of tin, lead, antimony or other metals, and are characterized by good wear resistance, high plasticity, good running-in properties, good thermal conductivity and good resistance to gum and adhesion. It is suitable for heavy load, high speed and other working conditions, but the strength is low, usually need to be attached to the bronze, steel or cast iron axle shaft tile to use ?

 ? Copper alloy? : Copper alloys include tin bronze, lead bronze and aluminum bronze, etc. Among them, tin bronze has the best friction reduction and is suitable for heavy-duty and medium-speed occasions; lead bronze is suitable for high-speed and heavy-duty bearings; aluminum bronze has higher strength and hardness and is suitable for low-speed and heavy-duty bearings. 

 ? Aluminum-based alloy? : Aluminum-based bearing alloys have better corrosion resistance and higher fatigue strength, suitable for partially replacing the more expensive bearing alloys and bronze, suitable for light loads and low speeds and not subject to shock load occasions ? ? Gray cast iron and wear-resistant cast iron? : These materials have a certain degree of friction reduction and wear resistance, suitable for light loads and low speed and not subject to shock load occasions.

 ? Non-metallic materials : such as plastics (e.g. phenolic resins, nylon, PTFE, etc.), suitable for environments that do not react to chemicals?

 ? Application scenarios and selection criteria for motor bearings? : ?

Micro or small motors? : Oiled bearings are usually chosen because they have fewer attachments, are maintenance-free, and help to simplify the structure?

 The choice of bearings for medium-sized or small motors Medium and large motors: Plain bearings are suitable for heavy loads. : Sliding bearings are suitable for heavy loads and shock-resistant occasions; rolling bearings are the most widely used and are suitable for various working conditions.

 ? Maintenance and care of motor bearings? :: The maintenance and repair of motor bearings is the most widely used: 

 ? Lubrication? : Rolling bearings are usually lubricated with grease or oil, depending on the requirements of the working conditions. 

? Regular inspection : Regular inspection of bearings for wear and tear, and timely replacement of damaged bearings to ensure the normal operation of the motor.

 These materials and selection criteria together ensure the stable operation and long-term service life of motor bearings under different working conditions.
