Graphite Plugged Bronze Bushings | Order Today
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, 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.
