SF-2Y
non-lead boundary lubrication
bearing is
improved
on the basis oSF-2X.
It can be applied to the field where
no
lead
is required. Now it's widely
used in textile machines, auto operating parts,
foodstuff machine and other middle speed,
middle load and grease lubrication occasions.

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 POM.
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. |
