Metal-based boundary lubricated bearings
Description: With metal materials (such as copper alloys, steel) as the matrix, solid lubricants (graphite, PTFE, MoS₂, etc.) are embedded. When lubrication is insufficient, it can still effectively reduce friction through the boundary lubrication film, which is suitable for extreme working conditions.
Advantages:
✔ High load-bearing capacity – the metal matrix provides excellent mechanical strength
✔ Self-lubrication – solid lubricants reduce friction and maintenance
✔ Extreme resistance – adapt to -200℃~300℃ high temperature/vacuum/corrosive environment
✔ Long life – boundary lubrication film significantly reduces wear
✔ Environmental protection and energy saving – reduce lubricant consumption and reduce pollution
Introduction to Metal-based Boundary Lubricated Bearings
Metal-based boundary lubricated bearings are special bearings based on metal materials combined with solid lubricants. This product is suitable for use in environments with poor lubrication conditions, especially in high temperature, heavy load, high vacuum or corrosive environments. Its metal matrix provides strength support, while the solid lubricant reduces friction and wear, thereby extending the service life of the equipment.

FAQ
Q1: How is it different from traditional bearings?
A1: Traditional bearings require lubricants to maintain operation, while metal-based boundary lubricated bearings can still run smoothly under poor lubrication conditions.
Q2: Is it necessary to add lubricant frequently?
A2: Self-lubricating products generally do not need to be frequently replenished with lubricants, but in specific scenarios, they can be replenished in appropriate amounts to extend service life.
Q3: What is the applicable temperature range?
A3: Depending on the material selection, the applicable temperature can reach -200°C to 300°C, or even higher.
Q4: Will the solid lubricant fall off?
A4: Solid lubricants are usually optimized and firmly bonded to the metal matrix, and will not fall off during normal use.
Q5: Can it be used for low speed and heavy load?
A5: Yes, this bearing is designed for low speed and heavy load applications and performs particularly well.
Q6: How to ensure its service life?
A6: By selecting appropriate materials and lubrication design, combined with optimized manufacturing processes, the service life can be greatly improved.
Q7: Can it be customized as required?
A7: The size, material and lubrication method can be customized for different working conditions to meet customer needs.
Metal-based boundary lubricated bearings are widely used in industrial fields and special environments due to their excellent wear resistance, high temperature resistance and maintenance-free properties. They are an ideal choice for reliability and economy.
