Large straight bronze graphite plugged bushings with extra hardness are mechanical components designed for heavy-duty applications requiring durability and low friction. These bushings are typically made from a bronze alloy, which offers excellent strength and wear resistance. The inner lining is impregnated with graphite, a natural lubricant that significantly reduces friction between the bushing and the mating shaft or rod.
The "inch size" refers to the dimensions of the bushing being measured in inches, rather than metric units. The "large" designation generally indicates that the bushings have a relatively large outer diameter, making them suitable for applications with larger shafts or requiring higher load-bearing capacity.
The "extra hardness" feature of these bushings is achieved through special heat treatment or alloy composition, which provides enhanced wear resistance and durability. This is particularly useful in applications involving high loads, high speeds, or both, where traditional bushings may experience premature wear or failure.
Straight bushings refer to the configuration of the bushing, where the bore is straight through the entire length of the component. This allows for smooth and continuous movement of the shaft or rod along the entire length of the bushing.
When selecting inch size large straight bronze graphite plugged bushings with extra hardness, it is important to consult with the manufacturer or supplier to ensure that the dimensions, material specifications, and hardness level are compatible with your specific application requirements. This will help ensure optimal performance and durability of the bushings in your system.
 

Straight Bushings Extra hard large size Graphite Plugged Bronze Bushings & Bearings | Self-Lubricating Bearings CHINA technology

 
Graphite Plugged Bronze Bushings are all self-lubricating and maintenance free. These bushings are machined out of continuous cast bronze and plugged with solid lubricant plugs. A bushing and it's mating surface should always be seperated by a film of lubricant. With Graphite Plugged Bronze Bushings no form of supplementary lubrication is required.
We provide all kinds of self-lubricating slippers, guide sleeve, wedge, and other products for packaging machinery, power transmission, mold, injection mold, stamping mold, and other application fields.

Performance

 
Graphite Plugged Cast Bronze Bushings can be utilized where heavy loads must be supported at low to medium speeds
 
The Plug Graphite Cast Bronze Bushing is able to withstand high temperatures up to 570 F
The self-lubricating feature allows bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.
Self-lubrication with specially embedded solid lubricants reduces friction. Coefficient of Friction: 0.04 to 0.2
