Sliding bushings, also known as plain bearings or sleeve bushings, are key components used in mechanical systems to reduce friction between moving parts, typically between a rotating shaft and a stationary housing. Their main function is to support radial loads, minimize wear, and ensure smooth and efficient motion.
These bushings are widely used in hydraulic and pneumatic systems, as well as in construction machinery, agricultural equipment, industrial automation, and automotive applications. They are available in both self-lubricating and standard lubrication-required versions.
Common materials include:
-
Bronze, zinc- or bronze-coated steel
-
Engineering plastics (PTFE, POM, composites)
-
Multilayer materials with embedded lubricant reservoirs
Sliding bushings are known for their durability, low friction coefficients, and resistance to corrosion, chemicals, and mechanical stress. They can operate in a wide range of temperatures and under various loads, making them ideal for high-performance and maintenance-free applications.
Choosing the right bushing depends on several factors, such as load type, sliding speed, operating temperature, lubrication method, and environmental conditions.
