Product Introduction
DALON SINTERED BRONZE BUSHING INTRODUCTION:
DALON self-lubricating Oil Embedded Sleeve Bronze Bearing 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 Oil Embedded Sleeve Bronze Bearing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.
DALON Oil Embedded Sleeve Bronze Bearing FAQ:
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:
1. Shaft linear speed - v
2. Applied load - p
3. 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.
