What Are Oilless Bushings? How Do They Work?
Oilless bushings, also known as self-lubricating bushings, are a type of plain bearing that does not require any external lubrication to operate smoothly. Instead, they are designed to work using a variety of other materials and mechanisms to minimize friction and wear.
Types Of Oilless Bushing
There are several types of oilless bushings:
- graphite plugged bronze bushing: the solid lubricant bushing, which uses a solid material, such as graphite, to provide lubrication between the bushing and the shaft. The solid lubricant slowly releases during use, providing a constant supply of lubrication without the need for oil or grease.
- polymer bushing, which is made from self-lubricating plastic material. These bushings have small pockets or channels built into the surface, which trap and distribute the lubricant evenly across the surface of the bushing.
- composite bushing, which uses a combination of materials, such as PTFE (polytetrafluoroethylene) and bronze, to create a low-friction surface. The PTFE acts as a lubricant, while the bronze provides strength and support.
