HB
Standard material specifications include: SAE 841, ASTMB 438 Grade 1 Type II,
CuSn 6-6-3, Sint B 50 & Standard impregnating oil conforms to SAE 30 specifications
Sintered Bronze and iron based self-lubricating bushings are made of two different functions:
The metallic alloy structure which supports and transfers the mechanical loads
The oil lubricant or graphite contents which separates two surfaces in relative motion and to reduce friction.
DALON BUSHING ADVANTAGE:
With no moving parts, sintered bronze bushings are the simplest type of bearing. Compared to ball and roller bearings, they generally handle higher temperatures and perform better in dirty environments. They are also intended by design to be self-lubricating, maintenance free and low cost.
DALON BUSHING APPLICATIONS:
DALON Sintered bronze bushing are recommended for following movements:
- Rotation
- Oscillation
- Linear
- Higher speeds requirement
- Higher loads requirement
- General assembly machinery, industrial vehicles, automation, farm machinery, sewing machines,
- bottling machines, key duplicating machines, electrical switchgears, mobility, toys, etc.
- Washing machines, fans, woodworking machines, vacuum cleaners, extractor fans.
- coffee machines, juicers, rotisseries, hand tools, air conditioning, boilers, etc.
- Lawnmowers, roller shutters, office swivel chairs, locks, garage doors, awnings, sliding windows,

DALON BUSHING 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
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.
