Material Features:

SF-2S is similar to foreign made DS bush, and may be operated without lubricant or under an trace of oil. It is of low friction, anticorrosion and is of long life. This is now applied in machines under oscillating motion and in open field or in corrosive environment such as hoisters, bulldogger, tower cranes, and printing or dyeing machines for textiles.

Application Feature:

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