Differences Between Oilless Bushing and Linear Bushings

Explanation of oil-free bushings: Oil-free bushings are high-strength brass bearings lubricated by oil gushing oil. This product has the function of traditional tin bronze bearing. After using high-strength brass, its HB hardness is doubled, so using...

Uses of Oilless Bushing

In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer chooses the lower hardness and better wear resist...

Industry Knowledge

Boundary lubricating bushings are a type of plain bearing that relies on a thin boundary layer of lubricant between the bearing surface and the shaft. They are commonly used in applications where additional lubrication is not practical, such as high-temperature or high-load applications.
Boundary lubricating bushings are typically made of materials such as bronze, graphite, or plastic, with the bearing surface containing small pockets or pores that retain lubricant. The lubricant is released as the bearing rotates or moves, creating a thin layer that separates the bearing surface from the shaft.
Boundary lubricating bushings are often used in applications such as automotive engines, industrial machinery, and high-temperature applications where traditional lubricants would break down or evaporate. They offer several advantages, including reduced friction and wear, longer service life, and improved performance in harsh and dirty environments.
However, boundary lubricating bushings can be less effective than other types of bearings in low-load or high-speed applications, as the lubricant film may not be thick enough to prevent metal-to-metal contact. They can also be more expensive than other types of bearings due to their advanced materials and manufacturing process.
