DU Bushing PTFE Self-lubricating Steel Bronze Sleeve Composite Bushing
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 Self Lubricating Sleeve 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 Self Lubricating Sleeve Bushing to release a thin layer of oil on the bearing’s surface.
DALON Self Lubricating Sleeve Bushing APPLICATIONS:
DALON Self Lubricating Sleeve Bushing are recommended for following movements:
- Rotation
- Oscillation
- Linear
Other different type of materials is available for specific requirements, such as:
- Higher speeds requirement
- Higher loads requirement
Main Advantages of DALON Self Lubricating Sleeve 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
