SF-2Y Marginal Lubricating Lead-Free Bush

Introduction:

SF 2Y Non-lead boundary lubrication bearing is improved on the basis of sf 2X.It can be applied to the field where non-lead is required.Now it's widely used in textile machines,auto operating parts and other middle speed,middle load and grease lubrication occasions.

Technical:

Load capacity:70N/mm2 
Temperature:-40~+130°C 
Speed limit:2.5m/s 
Friction coef(u):0.05~0.25 
PV LIMIT(Dry):2.8N/mm2 .m/s 
PV LIMIT(OIL):22N/mm2 .m/s

Application:

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 bushes can be applied in auto chassis,forging machine, metallurgical, civil engineering, power station, strip rolling industries etc.
6.SF-2Y is widely used in the machine that Lead is unacceptable.
