Porous Metal Bearings
Porous metal bearings are self-lubricating bearings made by powder metallurgy. Their porous structure can store lubricating oil and release lubricants during use, achieving long-term maintenance-free operation. The main materials include bronze, iron-based alloys, etc., which are widely used in low-speed and medium-load situations.
Advantages and characteristics of porous metal bearings
Self-lubricating property: Lubricating oil is stored in the pores, and there is no need to add lubricants frequently.
Low noise: low friction, suitable for equipment with high requirements for quietness.
Wear resistance: reduce wear and extend service life in long-term operation.
Cost-effectiveness: simple process, suitable for mass production, economical price.
Environmental adaptability: corrosion resistance, humidity and heat resistance, suitable for a variety of complex environments.
Analysis of porous metal bearings
1. What are porous metal bearings?
Porous metal bearings are bearings made of porous metal materials. They store lubricants through their unique pore structure, thereby achieving long-term self-lubricating effects. They are mainly made of metal powders such as bronze and iron-based alloys, and are processed and formed by powder metallurgy technology. They are widely used in low-speed and medium-load conditions, especially in occasions where frequent maintenance is difficult.

A3: Generally, no replenishment is required, but under high load or long-term continuous operation, regular inspection and replenishment of lubricants can extend the service life.
Q4: What are the unique advantages compared with rolling bearings?
A4:
Self-lubricating design, suitable for maintenance-free working conditions.
Lower noise and smooth operation.
Lower manufacturing cost, economical and practical.
Q5: Is customization supported?
A5: Yes, the size, shape and material properties can be adjusted according to specific needs to meet special application requirements.
5. Summary
Porous metal bearings have become an ideal choice for many industries due to their self-lubricating performance, low noise, wear resistance and cost advantages. Whether it is home appliances, industrial equipment, or automotive and medical fields, it performs well. Although it is not suitable for special scenarios with high speed and extremely high load, its stability and economy make it widely used in light industrial equipment and daily life.
When choosing porous metal bearings, you should consider the working conditions, load type, operating speed and ambient temperature comprehensively, and choose the most suitable product to obtain the best performance and longest service life.
