Metal self-lubricating bushings have a solid lubricant in line made of graphite or MoS2 with oil. While the bearing is completely dry. Because of the friction heat, solid lubricants run out to the working surface, lowering the friction coefficient. Base metals and alloys
Self-lubricating bearings function by having lubricant impregnated within the bearing’s sliding layer. Self-lubricating bushings, combined with embedded bronze bearings material, form a strong, resistant bearing surface.

To reduce friction, self-lubricating bearings use two key mechanisms. To begin, they embed solid lubricant films within the bearing surfaces. Second, these bearings have geometric patterns that distribute stress more evenly across the surfaces and reduce contact pressure between them.
In dry running conditions, self-lubricating sleeve bearings provide very good wear and low friction performance over a wide range of loads, speeds, and temperatures.

Graphite Plugged Bronze Bushing Plug with Self-Lubrication Bushings made of graphite – This item is milled and plugged cast bronze bushing with graphite plugs. The graphite serves as a lubricant. These are used in applications where the oil-impregnated bushing’s properties are insufficient.
SAE 841 bronze is designed for self-lubricating bushings and is sintered bronze sleeve bearings, oil-impregnated bronze bearings, and phosphor bronze bearings. SAE 863 bronze bearings are oil-impregnated bearings that are mostly used for self-lubricating powdered metal bearings (metal bushing sleeves) that are typically harder and stronger.

Plastic bushing material has a number of unique properties that make it suitable for a variety of applications and requirements.
Self-lubricating bushings contain oil-impregnated graphite plugs. Oil is drawn from the plug and lubricates the wear surface when the bushings reach 80-90°F due to friction between the bushing and guide post. As the oil and graphite are embedded into the bronze, they create a dark smear pattern on the worn surface.
A metal bushing that self-lubricates for longer life Sincerity, integrity, and experience Plain Bearings Made of Self-Lubricating Metal or Composite, Self-lubricating bearings have a longer service life and lower costs by up to 40%. They are oilless and require no maintenance. Plain bearings do not require external lubrication.
Our structural bearing products are permanent, self-lubricating, and oil-free, eliminating the need for routine maintenance. They provide unrivaled performance in harsh, corrosive conditions because they are made of high-quality metals such as bronze, stainless steel, aluminum, iron, and steel alloys. The Advantages of Structural Bearings
A self-lubricating sintered bushing is a metallic component with a high porosity (20-25% by volume) that has been impregnated with lubricant oil. Because the oil in the porosity provides constant lubrication between the bushing and the shaft, the system does not require any additional external lubricant. This type of sliding bushing can operate under hydrodynamic conditions due to self-lubrication.
