Sintered Iron Bearing Bushings
DALON SINTERED BUSHING INTRODUCTION: DALON self-lubricating Sintered Iron Bearing Bushings are manufactured of pressed iron 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.

Product Introduction
DALON Sintered Iron Bearing BushingsADVANTAGE:
With no moving parts, Sintered Iron Bearing 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.
Performance
An extremely wide range of operating loads, speeds and temperatures:
1. Dynamic loads from 6 to 75 MPa
2. Linear speeds up to 8 m/s
3. Operating temperatures from - 180°C to + 300°C
Suitable for use in a wide range of environments
1. Marine environment
2. Radio-active environments
3. Contact with corrosive liquids or substances incompatible with oils
4. Food preparation
Reduce of design and ownership costs
1. Maintenance-free operation
2. Lower cost compared to cast metal and machined bearings
3. Complex designs and forms possible
4. High dimensional accuracy
5. Excellent surface finish
6. Reduced weight compared to similar non-porous components
Safety
7. Permanent oil film lubrication
8. Low friction factor
9. Quiet operation
10. Good operation at low speed
11. Corrosion resistance

PRODUCTION PROCESS
The SINTERED IRON BEARING BUSHINGS sizes start from an interior diameter of 2mm and can go up to 250 mm, Length up to 80mm.
By P/M technology, The microroughness of the SINTERED IRON BEARING BUSHINGS surface enables amounts of lubricant to be transferred. To achieve the perfect surface properties for sliding function, process of impregnation under vacuum conditions by suitable lubricant can guarantee the capacity and the life of the bearing.
