What is the performance of engineering plastic bearing cages?
Bearing cage is an important component used in rolling bearings for railway vehicles. Safety performance must be high, and engineering plastics not only have certain strength, but also have high requirements for toughness. High-strength and toughened composite materials can meet the design of cages. Requirements, the current development of domestic and foreign cages is mainly nylon alloy engineering plastic bearing cage.
1. Excellent weatherability: Studies have shown that modified nylon is more suitable for bearing cages than other plastics.
2. Excellent oil resistance: can withstand a variety of gasoline, engine oil, gear oil, brake oil and lubricants;
3. Excellent mechanical properties: nylon has high mechanical strength and good toughness;
4. Excellent electrical insulation performance: high volume resistance, high breakdown voltage, excellent electrical and electrical insulation materials;
5. Self-lubricating and good friction resistance: nylon has good self-lubricating property, low friction coefficient, can be used as a transmission component, and has a long service life;
6. Excellent heat resistance: The heat distortion temperature of nylon engineering plastics is high. After the glass fiber reinforced modification, the temperature range of use can be greatly improved;
