The material of bearing steel 6000ZZ has outstanding advantages:
Mature technology, low cost, superior comprehensive mechanical performance, high hardness, high contact fatigue strength and good toughness, impact resistance and high reliability.
Disadvantages of Material Application of Bearing Steel 6000ZZ:
Insufficient adaptability in extreme working conditions, high centrifugation at high speeds, decreased hardness and dimensional stability at high temperatures, poor rust prevention performance, and high dependence on lubricating grease.
Application selection: Bearings made of 6000ZZ bearing steel are a very reliable and economical option. Significantly reduce costs without rust prevention requirements.
Outstanding advantages of ceramic ball bearing 6000:
Speed performance: Low density, low centrifugal force at high speeds, less prone to heating and wear
Strong durability: high hardness, low friction coefficient, long service life
Strong adaptability: high temperature resistance, corrosion resistance, insulation, non-magnetic
Disadvantages of Ceramic Ball Bearing 6000:
The material is very brittle, not resistant to impact, and the manufacturing cost is high, which is 10 times the price of bearing steel material.
Ceramic bearings are mainly developed for extreme working conditions. High temperature and corrosion resistance.
Q: What is the quality of 6000ZZ bearings made in China?
Answer: The quality of 6000ZZ bearings produced by BLH Bearing Factory is close to that of imported brands, suitable for various high-speed, low-noise, and heavy-duty working conditions.
Q: What is the service life of bearings 6000ZZ made in China?
Answer: The lifespan of BLH bearing 6000ZZ depends on the operating conditions. If it operates at rated load without lubrication failure and at room temperature, the lifespan of L10 (with a 10% failure rate) is approximately 15000-20000 hours.
Q: How to extend the service life of bearing 6000ZZ?
Answer: To extend the service life of the 6000ZZ bearing, it must be installed correctly, used according to the specified working conditions of the bearing, and lubricated and maintained properly.
