High-Strength Bronze Oilless Bushing | Lowers Cost & Increases Lubricating Capacity
Oilless Bushing Technology for Electric Motor | Size, Weight & Performance Critical
Self-Lubricating Bushings | Heavy Load, High-Temperature Applications
Solid Lubricants Bronze Bushing | High-Density Compounds, High Temp. Resistance
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.
Our solid lubricants are high-density compounds of graphite, , 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.
