    Our company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
    Valerie from California
    We import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts

Product Description

Graphite Plugged Bronze Bushings | Order Today, cast high-strength bronze using a specially formed graphite plug as a lubricant.

focuses on applications where size, weight, and performance are critical, lowers cost and increases lubricating capacity, lowers cost, and increases lubricating capacity.

For example, Graphite Plugged Bronze Bushings for the electric motor, oilless bushing technology offers significant benefits above and beyond current electric motors and generators.
Graphite Plugged Bushings are a complete line of Self-Lubricating Bushings that excel whenever standard lubrication is impractical, including heavy load, high-temperature applications. They are manufactured from a variety of Bronze Alloys, including C95400 Aluminum Bronze, C93200 Bearing Bronze, and C86300 Manganese Bronze.

  • Self Lubricated when standard lubrication is impractical
  • Performs well under various loads, types, and speed operations
  • Resists corrosive and hostile environments
  • Excellent performance in medium to high temperatures up to 600° F
  • Compatible with most viscous lubricants & Oil and Grease applications


Our solid lubricants are high-density compounds of graphite, PTFE, and metals. Lubricants are oriented to motion direction. Direction to be specified with the order. Application for temperature up to 350°C, NOT for water and vapor Use for temp. up to 80°C. Designed for use in water and humidity. Very low coefficient of friction





Have Incomparable performance under a high load, low-speed operation. Also, perform well without lubrication,
Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations
♦ Remarkable resistance to corrosion and resistance to chemical attack
Maintenance-free and save operating cost.
