Shaft Bushing Race for Automotive Parts
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 Shaft 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 Shaft Bushing to release a thin layer of oil on the bearing’s surface.
DALON Shaft BushingFAQ:
Q: Bushing type selection?
A: The metallic structure of the self-lubricating bushing can be made from a wide range of bronze or iron based alloys. To select the proper material for a given application, it is necessary to check the maximum values of the material characteristics in comparison with:
- Shaft linear speed - v
- Applied load - p
- pv (load x speed) factor
Shaft hardness and surface roughness and other parameters such as working
temperature and type of lubrication, etc.
Q: Lubricant Oil Selection?
A: Standard impregnating oil conforms to SAE 30 specifications
Lubricants are suitable for the temperature range from -40°C to 150°C
Also have option for customer to made special oil impregnation by self
Q: De-impregnation & Re-Impregnation?
A: De-impregnation required Degrease and wash in appropriate solvent
Eliminate the lubricant in a furnace heated around 400°C for 40 minutes under a neutral atmosphere such as N2, or with reducing agent such as N2 + H2
Re-Impregnation need Immerge during one hour the parts in an oil bath heated at a temperature between 60°C and 120°C, depending on oil viscosity .Then cool down in an oil bath back to room temperature. Finally drain and dry the self-lubricating bearings.
With a forward-looking vision, we have quickly invested in this Shaft Bushing Race for Automotive Parts industry to study and explore. We combine the company's existing resources with external resources, enrich the training methods, improve the company's training syllabus, and vigorously carry out various types of skills upgrading training and composite job training. Through exchanges and cooperation with well-known enterprises at home and abroad, we constantly innovate and accumulate to provide high-quality services for our customers.
