AST650 Series Structure AST650 Cast Bronze with solid lubricant plugsThe 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

• work without oil for long periods
• Extremely high load capacity, with good anti-wear and lower friction
• appropriate for low speed and high load
• Suitable for reciprocating, oscillation, motion where an oil film is hard to form
• Good chemical resistant and anti-corrosion characteristics

Typical Applications for the AST650 Series

This kind of bushing can be used under dry, high temperature, high pressure, corrosive, water, or other chemical environments when oil cannot be introduced. The AST650 Series bushings are widely used in automotive products line, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in the metallurgy industry, mining equipment, ships, turbo generators, hydraulic turbines, and injection molding machines
