High Quality Tungsten Carbide Shaft Bushings

High Quality Tungsten Carbide Shaft Bushings

DALON self-lubricating sintered bronze bushing are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity (20-25% in volume). The oil contained in the porosity provides a constant lubrication between bearing and shaft, the system does not need any additional external lubricant, allows this type of sintered bronze bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

Load Direction:

All Transmission Bushing are designed to handle radial loads, thrust loads, or a combination of the two. Radial loads are perpendicular to the shaft. Thrust loads are parallel to the shaft. Sleeve bearings handle radial loads. Flange sleeve bearings handle both radial and thrust loads. Thrust bearings handle thrust loads.

Startup friction causes these porous Transmission Bushing to release a thin layer of oil on the bearing’s surface.

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.

Performance
