Introduction
Thin wall thickness
is the most important peculiarity of the SF-4 Bush series.
They are light and compact, The inner-layer of the bush being
a kind of high density copper alloy of special compositions,
there is no hole and pit and provides higher load capacity
and fatigue strength, in compare with traditional casting
bronze bushes. It is manufactured by advanced technology and
machines, various kinds of lubricating indentations or grooves
may be readily provided on the sliding surface, and so the
re-oiling period is remarkably prolonged and the service lift
is accordingly prolonged. It¡¯s used in agricultural machinery,
construction machinery as well as engineering machinery etc.

SF-4 Advantages
1£® Saving copper material, saving labor hours of tuming ;
2£® Low weight and low cost;
3£® Re-oiling period is prolonged usually to 5 times;
4£® High load capacity, particularly fitted for relatively
rough wear, Mating surface;
5£® Ready for change, available from stock.
Provide standardized products: Cylindrical bushes P26,
flanged bushes P28, thrust washers P17¡¢P19, flat strip material
P17.
Provide non-standardized products: Cylindrical bushes, flanged
bushes, thrust washers, flat strip material, half bearing,
wear plate, SF-4 with steel bush.
