AST650 Cast Bronze with solid lubricant plugs - Metric
AST650 Series Structure
The AST650
Series Bushings are made of strong cast bronze based metal with
special solid lubricants embedded. The base metal withstands high load and the
solid lubricants provide for self-lubrication. The bushing shows
excellent performance without pre-lubrication under conditions of extreme
high/lower temperature with low speed.
This material provides a maintenance-free bushing solution, particularly for
high load, intermittent of oscillating motion.
AST650 Series Features
- May work without oil for long periods
- Extremely high load capacity, with good anti-wear and lower friction
- Particularly appropriate for low speed and high load
- Suitable for reciprocating, oscillation, or Intermittent motion where an oil film is hard to form
- Good chemical resistant and anti-corrosion characteristics
- Can be used in wide range of temperature from -40°c~+300°c
Typical Applications for the AST650 Series
