DALON Flanged Bronze Bushings MATERIAL STRUCTURE
MATERIAL CODE | BASIC METAL | ALLOY COMPOSITION |
Bronze based | CuSn9010/ SAE841 ASTM B438-70; SintA50/CuSnPb663 | Cu87.5~90.5,Fe1.0max,Sn9.5~10.5; CuSn663 |
Standard material specifications include: SAE 841 (CuSn9010), ASTMB 438 Grade 1 Type II,
CuSn 6-6-3, Sint B 50 & Standard impregnating oil conforms to SAE 30 specifications
Sintered Bronze and iron based self-lubricating bushings are made of two different functions:
The metallic alloy structure which supports and transfers the mechanical loads
The oil lubricant or graphite contents which separates two surfaces in relative motion and to reduce friction.

LUBRICATION OF FLANGED BRONZE BUSHINGS
Dry lubrication of FLANGED BRONZE BUSHINGS with solid lubricants under certain circumstances can achieve better friction coefficients than plastic bushings and casting bearings, for instance. Also FLANGED BRONZE BUSHINGS with content of graphite could reduce running sounds and good running properties.
An additional lubricant enables the longer service life to be increased.
FLANGED BRONZE BUSHINGS have a pore volume of between 15% to 30%, and these pores are used by oil impregnation for the bushing's entire service lifetime.
