C86300 Tin Bronze Flange Split Bushing CE Certificated Long Working Life

Product description

Flange Split Bushing is the contact part between sliding bearing and journal. It is a semi-circular cylinder with the shape of tile. It is very smooth. It is generally made of bronze, antifriction alloy and other wear-resistant materials. Under special circumstances, it can be made of wood, engineering plastics or rubber.

There are two types of bearing shells: integral type and split type. Integral bearing shells are usually called bushing. There are two kinds of integral bearing bush: oil groove and oil groove. Clearance fit is adopted between bearing bush and journal, which generally does not rotate with the shaft.It is suitable for high precision, shock resistance and large load. It is widely used in large and medium-sized equipment such as steam turbine, generator, large and medium-sized reducer, etc

Materials: bronze, polymer, graphite, ceramics

Production Feature :

The main function of copper bearing bush is to keep the stability of oil film through force bearing, to make the bearing work smoothly and bear the friction loss. It can be divided into axial thrust pad and radial pad. The rotating part of the radial pad supporting rotor and thrust bearing bears the role of axial positioning and axial thrust. It is an important static part.

The main damage of copper bearing bush is wear, scratch, peeling and burning. Due to wear, the alloy layer becomes thinner, the diameter of the bearing bush increases, the cylindricity and roundness errors increase, and the normal fit clearance with the journal is damaged, especially the upper pad of the connecting rod bearing and the lower pad of the main bearing. The main reason for alloy scratch is that the lubricating oil is not clean, the alloy layer is scratched by the abrasive in the lubricating oil, and the ring groove appears on the alloy surface when it is serious. The alloy layer will crack and flake due to fatigue. Generally, the bearing bush burning is caused by insufficient lubricating oil or improper fit clearance. In serious cases, the alloy of the bearing bush will be melted at high temperature, resulting in the bearing bush burning and axle holding.

Why Choose Us

Size requirements of copper bearing bush

The size of copper bearing bush shall be selected. When replacing the bearing bush, the bearing bush with the same repair size shall be selected according to the repair size of crankshaft journal. The bore size, cylindricity, roundness error and alloy thickness of bearing bush shall meet the technical requirements. The matching requirements of bearing bush and seat hole, and the matching of bearing bush and seat hole must have a certain degree of tightness to prevent the bearing bush from loosening and rolling in the work.
