What is Soild Lubricating Bushing?

Soild Lubricating Bushing consist of a metal matrix with precisely designed cavities that are filled with oil-impregnated graphite or molybdenum disulfide solid lubricants. During operation under oil-free conditions, frictional heat promotes the transfer of these solid lubricants onto the contact surface, effectively reducing the coefficient of friction.

Our products meet international advanced performance standards. Manufactured using high-precision CNC machinery and strict ISO/TS 16949 quality control protocols, we ensure consistent, high-quality bushings for all applications.

To accommodate diverse operating conditions and customized requirements, we offer an extensive selection of Soild Lubricating Bushing models. We also provide tailored solutions and develop new products based on specific customer needs.

Applications of Soild Lubricating Bushing

Soild Lubricating Bushing Material

The combination of high-strength bronze alloys and self-lubricating graphite ensures long-lasting, maintenance-free performance.

Materials & Structure:

We use a variety of high-performance bronze alloys tailored to different operating environments:

High-Strength Brass (CuZn25Al5):
  • Features: Offers excellent mechanical strength and wear resistance, suitable for high-impact loads and heavy friction conditions.
  • Applications: Mining equipment, heavy machinery.
 
Tin Bronze (CuSn10):
  • Features: Known for its exceptional corrosion resistance and good casting properties, ideal for humid and marine environments.
  • Applications: Marine engineering, shipbuilding.
 
Aluminum Bronze (CuAl10Fe5Ni5):
  • Features: Offers high corrosion resistance and strength, perfect for high-load, high-speed applications in high-temperature or acidic environments.
  • Applications: Oil drilling equipment, metallurgical machinery.

 

Lead Bronze (CuPb10Sn10):
  • Features: Excellent anti-friction and self-lubricating properties, making it ideal for high-temperature, heavy-load applications.
  • Applications: Power generation equipment, steel rolling mills, engine components.

Material Structure:

Graphite-Embedded Bronze Bushings consist of a high-performance bronze alloy base embedded with solid lubricant (graphite). The graphite blocks are precisely embedded into the bronze matrix’s friction surface. As the bearing operates, the graphite releases lubricant, reducing direct metal-to-metal contact, thus lowering wear and friction coefficients. This combination design ensures long-lasting, maintenance-free performance.

MYWAY Solid Lubricating Bushing FAQs

  1. Standard specifications are recommended for design applications. For non-standard requirements, please consult our technical team.

  2. Clean both inner and outer surfaces thoroughly before assembly to ensure complete removal of impurities and foreign particles.

  3. Applying lubricating grease to the friction surface prior to assembly can shorten the run-in period, improve operational smoothness, and extend service life.

  4. During assembly, press-fit the bushing gently into place. Avoid violent impact or hammering, which may cause deformation and reduce performance.

  5. For high-load conditions or reciprocating motions, secure the bushing to the housing hole using set screws.

  6. A black or gray-black lubricating film may form on the shaft surface during operation. Do not remove—this is a normal protective layer.

  7. For optimal performance, shafts should be made of materials with higher hardness than the bushing.

Yes. Graphite-embedded bushings are well-suited for various electric motor applications. Their self-lubricating nature ensures smooth operation without oil contamination or maintenance, especially in high-temperature or sealed motor designs where traditional lubrication is impractical.

While powdered graphite can be used as a temporary supplement, the most effective method is through embedded graphite plugs. At MYWAY, graphite is inserted into precisely machined cavities in the bushing wall during manufacturing. This built-in reservoir steadily supplies lubricant throughout the bushing’s service life, ensuring consistent performance without manual re-lubrication.
