SF-21 Pb-Free prelubricated bearing

Application characteristics: Non-lead boundary lubrication bushing is improved on the basis of SF-20.Therefore, it almost has the same properties with SF-20. but its application can be extended to where non-lead is required. Provide standardized products: Cylindrical bu

SF-22 Self-lubricating bearing

Application characteristics: SF-22 is similar to foreign made DS bush, and may be operated without lubricant or under a 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. Provide standardized products: Cylindrical bushes P15、P18, thrust washers P17、P19,flat strip material P17. Provide non-standardized products: Cylindrical bushes, thrust washers, flat strip material, half bearing, wear plate, SF-22 with steel bush.
