SF-2S
is similar to foreign made
DS bush, and may be operated without lubricant or under a trace of oil. It is
of low friction, anti-corrosion 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 textile.

Size Specification
Application Case |
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 bushed 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. |
