Oil Embedded Sleeve Iron Bearing

1.The metallic alloy structure which supports and transfers the mechanical loads
2.The oil lubricant or graphite contents which separates two surfaces in relative motion and to reduce friction.


DALON OIL EMBEDDED SLEEVE IRON BEARING MATERIAL STRUCTURE

Sintered self-lubricating bushings are made of two different functions:

1.The metallic alloy structure which supports and transfers the mechanical loads

2.The oil lubricant or graphite contents which separates two surfaces in relative motion and to reduce friction.

DALON OIL EMBEDDED SLEEVE IRON 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:

●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.


Q: Factory or Trading Company?

A: DALON established in 2002 and have two factories under DALON group with shareholders, one workshop specialized in OIL EMBEDDED SLEEVE IRON BEARING and another handles all sintered filter and silencers.
