Learn About Sintered Bronze Bearing
sintered bronze bearing is a porous bearing, It’s structural parts are produced by using metal powder as raw material and going through a special processing process. sintered bronze bushings are widely used in transportation machinery, household appliances, audio equipment, food machinery, printing machinery, automotive, instrumentation, textile machinery, aerospace, and other industrial fields.



Benefits of Sintered Bronze Bearings
Sintered bronze bearings offer numerous benefits, making them a preferred choice in various applications:
- Self-Lubrication: Their porous nature allows impregnation with lubricants, providing continuous lubrication and reducing maintenance needs.
- Highly durable, these bearings withstand substantial wear, with lubrication reducing friction and extending lifespan.
- Strong and structurally sound, they support heavy loads, ideal for demanding applications.
- Corrosion Resistance
- low friction
- Smooth lubrication leads to quiet operation, perfect for noise-sensitive applications.
- Effective across a wide temperature range, maintaining integrity and lubrication under extreme conditions.
- Can be manufactured in different shapes and sizes for customized solutions.
- Cost-Effective & Versatility
Tractor Sinter Bronze Bushing
Tractors, due to the dusty working environment, require the wearing parts to have good anti-abrasive wear characteristics and want the parts to maintain good lubrication conditions in operation as much as possible with a view to achieving a longer service life. Therefore, the application of sintered sleeve bushings in tractors is very valuable.
It mainly shows a low coefficient of friction, self-lubricating performance, not easy to scrape and bite in operation, and high load-bearing capacity.
Sinter Bronze bushings can also be dipped in sulfur, plastic, and other solid lubricants to further improve their performance.


Iron-Based Sintered Bronze Bearing Vs Copper-Based Sintered Bronze Bushing
Iron Sintered Sleeve Bushings Bearing
Iron-based Sintered Sleeve Bushings bearings have higher strength. It has less wear, low production costs, and can withstand larger loads, but it “has anti-seize and corrosion resistance than copper-based oil bearings. Therefore, iron-based bushes bearings are mostly used in mining machinery, agricultural machinery, machine tools, automobiles, and other places where the load is large and the speed is not high.
Copper Sintered Bronze Bushings
The copper-based Sintered Bronze Bushings are mostly used in instruments, control motors, household appliances, chemical machinery, etc., where the structure is compact, the load is small, the speed is high, the noise is low or the environment is humid and corrosive.
Sintered Bushing’ Application
Sintered Bushing In Automotive Applications
Because of its wear-reduction performance, corrosion resistance, and high electrical conductivity. They are used more in industries such as home appliances and automobiles. One of the most used is porous sintered bronze.
Applications In Micromotors
Many motors use rolling bearings because of the high noise, high cost, or refueling problems that can not be solved, for the performance of the finished product, and producion, must be changed to oil-containing bearings.
Sintered bushings are mostly used in general-purpose motors such as fan motors, jukebox motors, agricultural sprayer motors, etc., which can be set up with oil-filled mechanisms, while micro-motors such as cassette recorder drive motors, color TV motors, etc., which have special low-noise requirements and are inconvenient to refuel, need to be manufactured with electrolytic copper powder to improve the oil content and obtain a diffuse and uniform fine porosity structure.

Sintered Bushing
Sintered Sleeve bushings also called sinter bronze bushing, porous bronze Bearings, and Oil-impregnated Bronze Bearings. Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. there are three common types: straight, flange, and thrust washer.
