The Application of Self-Lubricating Bearings in Button-Making Textile Machinery


In modern textile machinery, lubrication issues have always been a critical factor affecting production efficiency and product quality. Traditional oil lubrication methods not only require frequent maintenance but also tend to cause environmental pollution. The advent of self-lubricating bearings has brought revolutionary changes to the textile machinery industry. This article explores the application of self-lubricating bearings in button-making textile machinery, highlighting how they reduce pollution, improve production efficiency, and enhance product quality.

Advantages of Self-Lubricating Bearings

Self-lubricating bearings are manufactured using tribology principles, combining a metal or alloy substrate with composite solid lubricants and high-hardness refractory metals or ceramics as the wear-resistant phase, using powder metallurgy technology. These bearings offer several significant advantages:

  1. Low Friction Coefficient: Self-lubricating bearings form a transfer film during operation, protecting the mating shaft and significantly reducing the friction coefficient.
  2. Wear Resistance: The use of high-strength and wear-resistant materials allows self-lubricating bearings to maintain excellent performance under high loads and high temperatures.
  3. Long Lifespan: Designed to operate within a temperature range from ambient to 1000 degrees Celsius, self-lubricating bearings have a significantly extended service life.
  4. Reduced Pollution: Eliminating the need for frequent oil lubrication, self-lubricating bearings avoid the environmental pollution problems associated with oil lubrication.

Application in Textile Machinery

Beijing Deffre Technology Co., Ltd. has developed oil-containing self-lubricating bearings that successfully address the short lubrication cycles and pollution issues of textile equipment. The application of these bearings in textile machinery is mainly reflected in the following aspects:

  1. Increased Production Efficiency: The low friction and high wear resistance of self-lubricating bearings enable textile machinery to run stably for extended periods, reducing downtime for maintenance and thus increasing production efficiency.
  2. Improved Product Quality: Since self-lubricating bearings maintain stable performance under high temperatures and high loads, the quality of the yarn is significantly improved, reducing yarn defects and breakages.
  3. Reduced Labor Intensity: The long lifespan and maintenance-free characteristics of self-lubricating bearings reduce the maintenance workload for workers, lowering labor intensity.

Broad Application Fields

In addition to their application in textile machinery, self-lubricating bearings are widely used in other high-tech fields such as metallurgical machinery, the automotive industry, shipbuilding, and chemical machinery. Their excellent performance, including long service life, low friction coefficient, wear resistance, oxidation resistance, and corrosion resistance, makes them an ideal choice across various industries.

Self-Lubricating Bearings in Button Manufacturing and Textile Machinery

Self-lubricating bearings offer several advantages over conventional lubricated bearings when used in button manufacturing and textile machinery:

Reduced Contamination and Pollution

One of the main benefits is the reduction of contamination and pollution caused by oil lubrication. Self-lubricating bearings have solid or liquid lubricants impregnated within the bearing material itself, eliminating the need for external lubrication. This prevents oil leaks and contamination of the machinery, textile products, and the surrounding environment.

Increased Production Efficiency

By eliminating the need for frequent re-lubrication, self-lubricating bearings reduce machine downtime and maintenance requirements. This leads to higher production efficiency and cost savings in labor and maintenance expenses.

Improved Product Quality

The consistent low-friction performance of self-lubricating bearings, even at high temperatures and loads, results in smoother operation of textile machinery. This helps improve the quality of yarn and fabric by reducing defects like yarn snarls or breakages caused by bearing issues.

Long Service Life

Self-lubricating bearings are designed to provide lubrication throughout their operational life, even as the bearing surface wears down. This results in an extended service life compared to conventional lubricated bearings, further reducing maintenance costs and downtime.

Diverse Applications

While particularly beneficial in textile and button manufacturing machinery, self-lubricating bearings are widely used in various industries such as automotive, aerospace, construction equipment, and more, due to their advantages of low friction, wear resistance, and contamination resistance.


The use of self-lubricating bearings in button manufacturing and textile machinery can significantly reduce pollution issues from oil lubrication, increase production efficiency and product quality, extend bearing life, and provide cost savings through reduced maintenance requirements.

The application of self-lubricating bearings in button-making textile machinery not only solves the pollution problems associated with traditional oil lubrication but also significantly improves production efficiency and product quality. With continuous technological advancements, self-lubricating bearings will play an increasingly important role in various fields, contributing to the sustainable development of many industries.
