DALON BUSHING INTRODUCTION:

DALON self-lubricatingFlanged Sleeveare manufactured of pressed copper and tin powders by sinter 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 Flanged Sleeve to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

DALON Flanged SleeveFAQ:

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:

21. Shaft linear speed - v
21. Applied load - p
21. 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

flanged sleeve have superb values in all engineering applications.

The properties of flanged sleeve are significantly defined by the high level of precision in manufacture and the porosity of the sintered material.
