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

SOLID LUBRICANTS BRONZE BUSHING

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

Characteristics:

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.
 

Standard material: CuZn25A16Fe3Mn3 + Graphite

Availability:

 
♦ Cylindrical oiles bushing, flanged oilless bush, thrust washer, and slide plate are a standard fabrication.
♦ Special designed solid metal bearing and material can be made according to your design.
♦ Other materials can be made based on your requirement.
