What Is A Bunting Bushing?

Bunting bushings manufacturers, a complete range of Bearings and Cast Materials all of which are made to the highest standards to optimize the performance of your product.

Bunting sintered bronze bearings have long conformed to ASTM chemical and physical properties, After forming, sintering, and sizing, the bunting bushings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation. Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10°F to 220°F.
Consult bronzeoilless.com if the application requires higher temperatures or other specific operating conditions.

Why Use Sintered Metals Bunting Bushings?

Bunting bushing is a sintered bearing made of metal powder as the main raw material by the powder metallurgy method. The bearings are porous and have the advantage of being able to adjust the number, size, shape, and distribution of pores more freely during the manufacturing process. By using the porous nature of the sintered body, it is impregnated with 10% to 40% (volume fraction) of lubricating oil and is used in a self-oiled condition.

Advantages of sintered metals bunting bushing.

(1) bunting bushing is low cost and cheap, suitable for mass production.
(2) Can absorb vibration, and the coefficient of friction is low, so the use of oilless bunting bushing is generally very low noise.
(3) Because the bunting bushing itself contains lubricating oil, and can play a self-lubricating role, it is suitable for some of the bearings that are not easily Therefore, they are suitable for some occasions where it is not easy to add oil.

Shortcomings Of Sintered Bunting Bushing

(1) Due to the porous nature of the powder metallurgy process, resulting in the bunting bushing itself is not high strength, difficult to apply to the occasion of high load.
(2) The sinter bronze bushing itself has poor wear resistance, and short life and the inner hole is easy to wear after a long time of use, resulting in large amplitude, noise, and other bad occurrences.
Bunting bushings as a basic part of electromechanical have been widely used in automobiles, business machinery, home appliances, power tools, audio equipment, computer-related equipment, and other industries.
The Oil-impregnated bunting bushings are widely used in many industries, such as automobiles, business machinery, home appliances, power tools, audio equipment, computer-related equipment, etc. Different working conditions have put forward different materials and performance requirements for bunting bushing bearing, for example, the general electric tools
For example, Oil-impregnated bunting bushings for general electric tools have special requirements for wear resistance, while bunting bearings for audio machinery need a low coefficient of friction, etc.

The Material Of Sintered Metals Bunting Bearings

1. Iron-based: Iron resources are abundant and easy to obtain, low cost, high strength, good wear reduction performance, good wear resistance, and high load capacity, it successfully replaced the casting of bartonite and bronze bearings. There are many qualities, mainly oil-impregnated sintered iron, iron-graphite, iron-copper-graphite, iron-sulfur-graphite, and sintered iron-based materials containing solid lubrication caf2, Mos2, etc.

2. Copper base: wear reduction performance, corrosion resistance, and high electrical conductivity. Therefore, it is widely used. Among them, the most used are porous bronze, sintered bronze – steel-backed bimetal, three-layer composites, and bronze-graphite materials.

3. Aluminum base: small density, high service life, twice as high as bronze oil bearing, wear resistance is also higher than iron-based oil, excellent thermal conductivity, can withstand higher loads, low operating noise, good vibration resistance, excellent corrosion resistance, and low cost. The mainly aluminum-copper system, Al-Cu-Mg-Si system, sintered aluminum-graphite system, aluminum-lead alloy-steel-backed bimetal bearings, etc.

Selecting The Right Bearing For Your Application

  • bronze thrust washer

    For many decades, VIIPLUS has been supplying prepackaged thrust and journal bearing systems with significant advantages for pump applications. Pumps are vital to the industrial process and are designed to operate for many years, yet they consistently come out of service due to product leakage from mechanical seal failure. Mechanical seals can fail as a result of axial movement and shaft deflection caused by bearing damage. Protect against bearing damage to significantly increase pump reliability.

  • phosphorous bronze busing, brass sleeve bushing

    Phosphor bronze has higher corrosion resistance, is resistant to wear and tear, and does not spark on impact. For medium speed, heavy load bearings, working at a maximum temperature of 250 ℃. With self-aligning, insensitive to deflection, shaft bearing force uniform high bearing capacity, can be subject to radial load at the same time, self-lubrication without maintenance and other characteristics. Tin-phosphor bronze is an alloy copper, with good electrical conductivity, not easy to heat, to ensure the safety of the same time with a strong fatigue resistance.

     

  • SAE841 bronze bushing, Slide bearing

    SAE 841 bearings have higher corrosion resistance, wear resistance, and do not spark when impacted. It is used for medium-speed and heavy-load bearings, and the maximum working temperature is 230~280℃. It has the characteristics of self-aligning, insensitive to deflection, uniform bearing capacity, high bearing capacity, radial load at the same time, self-lubricating and maintenance-free.
