Project Description

SAE 841 Bronze Bushing – Oil Impregnated Bronze Bearing

  • Standard stock products

  • SAE 841-copper (87-90%), tin (8-9), carbon, other elements

  • Powdered metal bronze provides interconnected reservoirs for oil

  • Vacuum impregnated with SAE 30 oil during the manufacturing process (approx. 19% by vol.)

  • Self-lubricating – when in motion oil rises to the surface for lubrication and restores itself when at rest

  • Ideal for heavy loads at moderate speeds or light loads at high speeds – max Pv 50,000, P-Load 2,000, V-SFM-1,200

SAE 841 Sintered Bronze – Oil Impregnated

Beautifully crafted leather products.

Sintered bronze is an engineered material made by heating and compressing bronze powder. It is known for its durability, strength, and ability to withstand high temperatures. One type of sintered bronze that has gained significant popularity in the industrial world is SAE 841 sintered bronze.

The SAE 841 bronze bushing is one of the best-powdered metal bearings on the market. This material is oil impregnated, which makes it a perfect fit for various applications. Using a proprietary mixing and sintering process with a uniform grain structure and spherical pores results in superior strength, a low coefficient of friction, and a uniform oil layer for mating shafts.

SAE 841 Sintered Thrust Washers

Beautifully crafted leather products.

Our SAE 841 bronze bushings are available as Sintered Bronze (SAE 841) wear plates, SAE 841 thrust washers, Sintered Bronze Flange Bushings, and SAE 841 sleeve bearings. They are rigid, temperature-resistant, and high-strength parts formed through the process of sintering, or powder metallurgy.
Sinter bronze bushing has a proven record of unexcelled wear resistance and long life. They hold closer tolerances and can be made self-lubricating through oil impregnation. Because of smoother action and self-dampening features, powder metal assures a quiet operation.

Advantages Of Oil-Impregnated Sintered Bronze

SAE 841 sintered bronze has several advantages due to its oil-impregnated properties. Some of these advantages include:

  • The oil-impregnated feature of SAE 841 sintered bronze makes it a self-lubricating material. It can lubricate itself, reducing the need for manual lubrication, which saves time and reduces maintenance costs.
  • reduces friction between moving parts. This property reduces wear and tear, increasing the lifespan of the material and any machinery that uses it.
  • helps to prevent rust and other forms of corrosion. This property makes it suitable for use in harsh environments.
  • From the automotive industry to industrial machinery and agricultural equipment, SAE841 STD Plain Bearings find a home in various applications. Their versatility and reliability make them indispensable in ensuring smooth operations across diverse sectors.

Maintenance and Care of SAE 841 Sintered Bronze

To maintain and care for SAE 841 sintered bronze, follow these tips:

Lubrication Your SAE841 Sinter Bronze Bushing

Although SAE 841 sintered bronze is self-lubricating, it still requires occasional lubrication to maintain optimal performance.

Cleaning Bushings Regularly

Clean SAE 841 sintered bronze bushings regularly to remove dirt, dust, and debris that can reduce its lifespan.

Inspect sinter bushings regularly for signs of wear and tear, such as cracks or deformation.

Store SAE 841 sintered bronze in a dry and clean place to prevent damage from moisture or dust.
