Bronze With Lubricant Plugs Embedded
1 in stock
Description
Bronze With Lubricant Plugs Embedded are made of strong cast bronze-based metal with special solid lubricants embedded. The base metal withstands high loads and the solid lubricants provide self-lubrication. The bushing shows excellent performance without pre-lubrication under conditions of extremely high/lower temperature with low speed. This material provides a maintenance-free bushing solution, particularly for high-load, intermittent oscillating motion.
Features Of Solid Lubricant Bronze Bushing
- 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
