DALON self-lubricating iron sinter,sintered iron bearing iron bushing is a metallic component with high porosity (20-25% in volume), impregnated in a lubricant oil. The oil contained in the porosity provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant. Self-lubrication allows this type of sliding bearing to work under hydrodynamic conditions, resulting in a very low friction coefficient.
DALON Self-lubricating sintered bearings have some advantages compared to other types of dry sliding bearings:– Reliability. The constant oil presence eliminates the risk of seizure, and allows the bearing to work during thousands of hours without wear.– Economy. Maintenance-free, no need for lubricants.– Performance. Able to work under loads of up to 10 MPa, and speeds up to 2.5 m/s. The maximum working PV is is the range of 2.45 N/mm2•m/s, but can be surpassed in special cases. The dimensional precision is very high (up to IT 5 in diameter), and produces extremely low noise.
The main applications for DALON self-lubricating sintered bearings are:1. Automotive electrical or mechanical equipment, such as:– Starters.– Active driving elements: Brakes, steering, transmission, shock absorbers, …– Cooling: Radiator, fans, cooling systems, ….– EGR systems.– Fuel pumps.– Comfort and Security: Wipers, window regulation, mirrors, seats, sunroofs, …2. Universal or customized electric motors and gearboxes of medium-low power.3. Linear and rotary actuators, pneumatic, hydraulic and electromagnetic.4. Household appliances: Washing machines, fans, extractor fans, shaving machines, depilators, juicers, rostisserie, air conditioning, handtools, coffee machines, wishking machines, vacuum cleaners, lawnmowers, boilers, etc.5. Home appliances: Locks, garage doors, awnings, roller shutters, sliding windows, office swivel chairs, trolley rolling wheels, hinges, furnitures, gardening, etc.6. Industrial: Bottling machinery, carpenter machinery, assembly machinery in general, automation, key duplicating machines, sewing machines, industrial vehicles, electrical switchgears, mobility, medical, catering, farm machinery, toys, etc.
The manufacturing process of sintered components is certified as ecological, because the material waste is very low, the product is recyclable, and the energy efficiency is good because the material is not molten.
Drawing of Sintered Iron Bushing
Manufacture Process1.RAW MATERIAL / MIXING
Sinter powders can be of pure metal (iron, copper), or alloyed powders (bronze, steel, etc.)mixed with different alloying elements, depending on the composition of the final material (such as graphite, nickel, copper,…), with an organic solid lubricant.
The powder mixture is compacted inside the tooling, which has the negative shape of the final part. The tool is an element of a very high precision, and high durability. The powder is filled into the tool cavity of a mixer by gravity, and pressure within 200 to 1500 MPa is applied onto it depending on the final density to be achieved.
Sintering in continuous furnaces, under controlled speed and at an atmosphere with controlled chemical composition by temperatures between 750 and 1300°C depending on the material
The result of these basic operation is a metallic part with a certain micro-porosity, high dimensional precision, and perfectly functional.
