TY-FU1 Oil Impregnated Sintered Bronze Bearings

Powder Metallurgy Bronze Bushings

I. Manufacturing Process & Material Properties

• Core Process: High-pressure compaction → High-temperature sintering → Vacuum oil impregnation (oil penetrates uniformly into the fine pores of the metal).

• Material Specifications: Base material: SINT A51 or equivalent powder-metallurgy alloys, impregnated with 18%–20% mineral oil; porous sintered bronze structure provides both self-lubricating performance and dimensional stability.

• Alternative Names: Oil-impregnated sintered bronze bearing, sintered bronze bushing,Powder Metallurgy Bronze Bushings

  II. Key Performance & Operating Conditions

• Operating Characteristics:

  • Suitable for medium speed, low-load, and short-duration dry-running applications, relying on internal oil reserves for temporary lubrication.

  • Wide operating temperature range, adaptable to various environmental conditions.

  • High dimensional accuracy in both inner and outer diameters ensures reliable assembly.

  • Excellent wear resistance and corrosion resistance for extended service life.

• Advantages:

  • Maintenance-Free: Self-lubricating properties minimize the need for additional servicing.

  • Cost-Effective: Mature manufacturing process lowers overall operational costs.

  • Dimensional Stability: Precision forming and sintering processes ensure long-term stability of product dimensions.

III. Functional Role & Application Fields

• Core Function: Serves as a sleeve bushing primarily for linear motion, guiding movement while reducing component friction. It can also reinforce shafts or fasteners, reduce bore diameter, or replace worn bushings in wheels and similar parts.

• Application Scope:

  • Industrial Equipment: Small electric motors, power tools, textile machinery, chemical machinery, machine tools, printing machinery.

  • Consumer & Commercial Devices: Household appliances (e.g., washing machines, air conditioners), office equipment (e.g., printers, copiers).

  • Automotive Industry: Suitable for various internal automotive transmission and support components.
