Self-lubricated Brass Alloy Bushings SPW

SPW

Brass alloy with embedded solid lubricant bushing is to open cavities of appropriate size and orderly arrangement on the metal friction surface of the bushing matrix. It was embedded a molded solid lubricant with unique self-lubricating properties in the cavities (the solid lubricant area is generally 25% - 35% of the friction area) and made of self-lubricating bushings.

It has been used in metallurgy of continuous casting machine, rolling equipment, mining machinery, shipbuilding, gas turbines and other high temperature, high load, low speed heavy load and other occasions.

Material

High Tensile Brass Alloy + Graphite Solid Lubricant Embedded

Features List
  • May work without any oil for a long period.
  • Extremely high load capacity, good anti-wear and lower friction.
  • Particularly appropriate for low speed and high load.
  • Suitable for reciprocating, oscillating or intermittent motion where oil film is hard to be formed.
  • Good chemical resistant and anti-corrosion characteristics.
  • Can be used in wide range of temperature from -40°C - +300°C.
  • Low maintenance frequency.
