SF-2 Marginal Pb-free Self-lubricating Bearing

Marginal Pb-free Self-lubricating Bearing

Features

SF-2 Marginal Pb-free self-lubricating bearing is used steel-backing as its structure, sintered porous bronze as its interlayer, surface inlaid the modified POM. Suitable for marginally lubricated and dry operation on the conditions of lubrication indents grease. It has been widely applied to metallurgical machinery, Mine machinery, water conservancy machinery, vapor locomotive, building machinery, agriculture machinery, steel rolling industry etc.

Material Structure

  1. POM with fiber 0.3~0.5mm
  2. Porous bronze 0.2~0.3mm
  3. Steel backing 0.4~2.2mm
  4. Copper plating 0.008mm

Available forms

Bushes, flanged bushes, WC thrust washers, strip and other non-standard parts and so on.

Application Feature

  • Good load capacity and anti-wear.
  • It is used in high load capacities and low speed with rotational,oscillating or frequent stop-start motion.
  • It can work long time without oil in the condition of boundary lubrication,under oil or grease lubrication interval, the work is longer.
  • It is machinable for the thicker of POM.
  • The bushes can be applied in auto chassis,forging machine, metallurgical, civil engineering, power station, strip rolling industries etc.
