Sintered Bushing Materials
Bronze
Sintered bronze oil-impregnated bearings have long service life, low operating noise, corrosion resistance, and are the most widely used.
Iron
Sintered iron oil impregnated bearings have the advantages of low price, excellent self-lubricating performance, fatigue resistance, and high strength. However, they have poor corrosion resistance and the lubrication effect is not as good as bronze.
Iron & Copper
Sintered bushings have good corrosion resistance and are cheaper than bronze sintered bronze bushings.
Standard Sintered Bearing
BLUE offer a multitude of oil-impregnated bushings, including sintered iron bushings, sintered bronze bushings, and sintered iron & copper bushings.
All of these standard oil-impregnated bushings are in stock and available for direct purchase.
Our sintered bronze sleeve bushings come in a range of sizes, with inner diameters from 3mm to 60mm, outer diameters from 5mm to 70mm, and lengths from 3mm to 65mm.

Working Principle of Sintered Bushings
During the operation of the sintered bushing, the lubricating oil expands from its pores under the suction of the rotating shaft and the influence of the temperature rise, forming an oil film to reduce friction.
When the oil impregnated bushing stops working, the capillary force sucks the lubricating oil back into the pores of the sintered bushing.
However, when the machine starts up, the speed is low and the lack of hydraulic pressure causes direct contact between the bearing and the shaft. This leads to increased friction, wear and temperature rise, which may cause loss of lubricating oil.
Applications of Oil Inpregnated Bushings
Oil impregnated bushings have low cost, good self-lubrication effect, low maintenance cost, and are widely used.
Automobile
Electric windows, electric seats, wiper motors, starter motors, cooling systems, brake systems, etc. in automobiles
Industry
Assembly machinery, copiers, sewing machines, automation equipment, electrical switchgear, agricultural machinery, etc.
Household appliances
Fans, coffee machines, juicers, depilators, barbecue machines, vacuum cleaners, lawn mowers, air conditioners, hand tools, etc.

Sintered Bushing Manufacturing Process
Powder metallurgy is a precision manufacturing process with a continuing and stable accuracy of up to 0.01mm, which requires strict control at each stage to ensure the quality of the final part. Any deviation or error during the process may result in the rejection of the entire batch.
Designing
Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.
Tooling
Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.
Mixing
Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.
Compacting
Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.
Sintering
Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.
Sizing
Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.
Tumbling
Tumbling removes burrs and flash from a part's surface by vibrating it with abrasive media, such as stone or ceramic, resulting in a smoother finish.
Machining
Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.
Blackening
Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.
Hardening
Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.
Inspecting
The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.
Packaging
BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.

FAQ's
Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
As we know, sintered bushings contain numerous internal pores, which makes them suitable for oil impregnation.
Typically, the bushings are placed in a mesh basket and submerged in an oil tank. A vacuum is then applied to remove air from the pores, allowing the oil to fill them.
Afterward, air is reintroduced to create atmospheric pressure, further pushing the oil into the bushing’s pores.
