SF-20 Prelubricated bearings

■ Structure

1、  POM with lead 0.3-0.5mm

2、Porous bronze 0.2-0.3mm

3、Steel backing

4、Copper plating 0.002m

■Tech.Data

Max.Load Static 250N/mm2
Friction Cofee. 0.05-0.25u
Dynamic 140N/mm2 Speed limit(Oil) 2.5m/s

Oscillating 60N/mm2 Thermal conductivity 2.03Kcal/M.br.C

PV limit Dry 2.8N/mm2×m/s Coeff.of linear expansion 51×10-6per℃
Oil 22N/mm2×m/s



Initial pre-lubrication at assembly required




Temp.limit -40℃~+130℃



■ Application characteristics

1、  It is superior to those known marginal lubricating materials when lacking of lubrication oil.

2、Owing to its thick and hard surface of friction, it has the advantage of low wear.

3、  High mechanical strength,it can stand heavy dynamic and static load. It is used in high load capacities and low speed with rotational, oscillating or frequent stop-start motion.

4、  It can work long time without oil in the condition of boundary lubrcation,under oil or grease lubrication Interval, the work is longer.

5、  It is machinable for the thicker of POM.

6、  The bushes can be applied in auto chassis, forging machine, metallurgical, civil engineering, power station, strip rolling industries etc.

■ Provide standardized products:Cylindrical bushes P15、P18,thrust washers P17、P19, flat strip material P17.

  provide non-standardized products:Cylindrical bushes, flanged bushes,trrust washers,flat strip material,half bearing,wear plate,SF-20 with steel bush.
