Oil-Free Guide Bushings/ Oil Free Slide / DIN1530/ISO8020

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.

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.

Main Advantages of DALON Slide Bushing

1) Powder metallurgy can ensure the accuracy and uniformity of the material composition ratio.

2) Suitable for producing products of the same shape and large quantities, low production cost.

3) The production process is not afraid of oxidation, and no material pollution will occur.

4) No subsequent machining processing is required, saving materials and reducing costs.

5) Most difficult metals and compounds, pseudo alloys, porous materials can only be manufactured by powder metallurgy
