C93200 BRONZE BUSHING standard geometries such as cylindrical, flanged and spherical bearings, DALON also developing in P/M of complex types for special purpose requirements.

As rich and long experience in P/M technology, DALON also offer Technical support for customers in the design and application of C93200 BRONZE BUSHING , selection of available materials and lubricants for Special-purpose equipment compression molds, furnaces, handling, sizing, deburring and impregnation.


TYPES

SPHERICAL C93200 BRONZE BUSHING

Guarantees autonomous re-alignment of the bearing bore. The bore diameter remains unchanged when installing the spherical bearing. However, the installation is somewhat more complicated.


SPHERICAL C93200 BRONZE BUSHING WITH RING

The main purpose of the extension is to compensate for any in-between spaces.

DALON BUSHING MATERIAL STRUCTURE

MATERIAL CODE

BASIC METAL

ALLOY COMPOSITION

Bronze based

SAE841 ASTM B438-70; SintA50

Cu87.5~90.5,Fe1.0max,Sn9.5~10.5; CuSn663

Standard material specifications include: SAE 841, 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.
