Polymer Lined Steel Bushing Series: Modes of Lubrication

The Polymer Lined Steel Bushing series operates effectively in different lubrication conditions depending on the thickness of the lubricant film developed between the bearing and the mating surface. Understanding these lubrication modes can help optimize bearing performance and lifespan. The three primary modes of lubricated bearing operation are:

1. Hydrodynamic Lubrication

Hydrodynamic lubrication is a state where a full film of lubricant separates the bearing surface from the mating surface. The load is fully supported by this fluid film without any direct contact between the metal surfaces. This is often achieved when the bearing and the mating surface are moving at sufficient relative speed to create a pressurized lubricant film. Hydrodynamic lubrication results in minimal wear, allowing the bearing to have a longer service life.

However, this mode is difficult to maintain at lower speeds, during start-up, or shut-down where the speed may not be enough to sustain the lubricant film.

2. Mixed Film Lubrication

Mixed film lubrication is a transitional mode between hydrodynamic and boundary lubrication. It occurs when the speed or load conditions are such that a complete lubricating film can’t be maintained, and direct metal-to-metal contact occurs in spots. The lubrication state is thus ‘mixed’ since some areas are under hydrodynamic lubrication (full film separation) while others are experiencing direct contact. The aim is to maintain as much hydrodynamic lubrication as possible to minimize wear.

3. Boundary Lubrication

Boundary lubrication occurs when the lubricant film is not thick enough to completely separate the bearing and mating surfaces, and metal-to-metal contact occurs. The lubricant in this case provides a protective layer over the metal surfaces to reduce wear and friction during these contact instances. This mode of lubrication is often present at low speeds, high loads, or during start-up and shut-down.

The Polymer Lined Steel Bushing series, featuring an inner lining of PTFE or POM, is designed to function efficiently in all these lubrication conditions due to the self-lubricating properties of these materials. It is crucial to understand the operating conditions to select the right lubrication strategy for maintaining optimal bearing performance.

Our range of Metallic and Self-Lubricating Bushings demonstrate exceptional performance in a variety of hydraulic applications, where oil-lubrication is commonly used. They excel in wear resistance and frictional performance, optimizing the overall operation and extending the lifespan of the machinery.

One of the key features that enables this superior performance is the utilization of Red Polytetrafluoroethylene (PTFE) in the production of our bushings. Red PTFE is known for its excellent wear resistance, particularly under steady load, oil-immersed boundary lubrication conditions.

Key Features in Hydraulic Applications:

Exceptional Wear Resistance: The Red PTFE lining in our bushings exhibits excellent wear resistance. This significantly reduces the frequency of bushing replacements, thereby lowering maintenance costs and downtime.

Optimal Frictional Performance: Our bushings show superior frictional performance, ensuring smooth operation in various hydraulic applications. This reduces the risk of overheating and component wear, and helps to increase the overall efficiency of the hydraulic system.

Performance in Oil-Lubricated Applications: The bushings perform exceptionally well in oil-lubricated applications, common in many hydraulic systems. They can withstand the boundary lubrication conditions that often occur in these systems, demonstrating high levels of reliability and durability.

Steady Load Capacity: Under steady load conditions, our bushings maintain their wear resistance and continue to operate effectively, making them ideal for applications with consistent operational demands.

Our Metallic and Self-Lubricating Bushings are a robust and efficient choice for hydraulic applications, providing reliability and performance that can enhance the overall operation of your hydraulic systems.
