Brief Description
Bronze and Solid Lubricants – A Powerful Combination
Oil-free bearings, also known as self-lubricating bearings, enhance productivity and offer cost and time savings due to their resilience against both high and low temperatures, corrosive scenarios, debris, and shock impacts.
Among these, Graphite Plugged Oil Bearing stands out. It comprises a cast bronze alloy foundational material incorporated with unique solid lubricants. The core metal offers resistance to high loads, while the graphite ensures continuous lubrication. Impressively, this oil-free bearing variant excels even without lubrication during both high and low-temperature conditions at low speeds. Specifically, JDB bearings equipped with graphite plugged oil emerge as a superb, maintenance-free solution, especially beneficial under significant loads and sporadic oscillatory motions.
The Concept of Dry Lubrication
Simply put, dry lubrication is the utilization of a solid lubricant. These lubricants, typically in powder or solid form, thrive under challenging conditions like high temperatures or corrosive environments where traditional oils or greases falter. Common constituents include natural graphite, molybdenum disulfide, and P.T.F.E.
How does it function? A solid lubricant, usually a polymer, fills the bearing’s inner space, consisting of countless micropores saturated with oil. During bearing operation, the oil gets released, and during idleness, it’s reabsorbed.
Benefits of Solid Lubricating Bearings:
- Long-duration functionality without needing oil.
- Incredible load capacity coupled with low friction and anti-wear properties.
- Optimal for low-speed, high-load situations.
- Supports one-directional axial loads.
- Flexibility in design regarding shape and size.
- Operative in diverse temperatures, ranging from -40℃ to +300℃.
Tailored Bearing Designs with Bronze and Solid Lubricants
Bearing design, influenced by material choice and geometric considerations, is curated based on its specific application. Each bearing is uniquely crafted, considering the particular load, environmental, and temperature demands of its intended use.
Graphite Lubricating Bearings – An Overview
Graphite plugged solid lubricating bearings, synonymous with graphite plugged bronze bushings, are a distinctive self-lubricating bearing subtype. They find extensive application, particularly in scenarios where consistent maintenance isn’t feasible.
Here’s a quick rundown of their operation: As the bearing surface encounters friction, the resultant heat prompts the graphite to dispense minuscule lubrication amounts, reducing friction and ensuring optimal bearing performance.
Prominent Features of Graphite Plugged Bearings:
- Continuous self-lubrication via solid graphite.
- Robust load capacity due to the bronze foundation.
- Stellar durability even under high load and temperature.
- Resilience in demanding environments, including dust exposure, varied temperature scales, and corrosive settings.
- Hassle-free post-installation – no further lubrication or upkeep required.
- Versatility in application across machinery, automotive sectors, water systems, and more.
However, these bearings may not be suitable universally. For high-speed applications, traditional rolling-element bearings might be a better fit.
