Bush Bearing Material: Understanding the Basics

Bush bearings, also known as plain bearings, are an essential component in many mechanical systems. They help reduce friction and wear between two moving parts and also assist in maintaining their relative position. Bush bearings are typically made of metal or non-metal materials, with each having its advantages and disadvantages. In this article, we will focus on the various types of bush bearing materials, custom bearing bush size, and provide a table of different self-lubricating bearing bush types and their technical data.

Types of Bush Bearing Materials

Beautifully crafted leather products.

Bronze: Bronze is a popular material for bush bearings due to its excellent wear resistance, high strength, and good thermal conductivity. However, it requires lubrication to function properly, and in certain conditions, it can suffer from corrosion.

Graphite: Graphite is an excellent self-lubricating material and does not require additional lubrication. It has a high temperature tolerance and low coefficient of friction, making it ideal for use in high-temperature applications.

Plastic: Plastic bush bearings are made from various types of thermoplastics, such as PTFE, nylon, and acetal. They are lightweight, corrosion-resistant, and offer excellent wear resistance. However, they have lower load-bearing capacities compared to metal bush bearings.

Steel: Steel bush bearings are the most common type of bush bearing material. They are strong, durable, and can withstand high loads and temperatures. However, they require lubrication to prevent wear and tear.
