Self-lubricating bearings are a type of engine bearing that uses a dry lubricant to reduce friction between moving parts. They are commonly used in automotive and aerospace applications where traditional oil-based lubricants can’t be used.
What does “self-lubricating” actually mean? Lubrication is initially associated with grease or oil, but its presence does not necessarily mean dirty fingers when handling slide bearings. Lubrication actually only means reducing friction and wear between (machine) elements or friction partners that move relative to one another.
Self-lubricating bearings retain their load-carrying capacity at high temperatures. They can operate where rolling-element bearings fail due to fatigue, and where conventional lubricants oxidize rapidly. Furthermore, many self-lubricating polymers resist corrosion very well.
Self-lubricating bearings work by having lubricant impregnated within the sliding layer of the bearing. This lubricant can either be liquid (oil) or solid (graphite, MoS2, lead) based on the requirements of the application (such as operating temperature).
Self-lubricating bearings and sliders embedded with solid lubricants, under the action of friction heat, expand the solid lubricant, automatically transfer to the friction surface, form a layer of lubricating film to prevent metal-to-metal contact, thereby reducing friction factor and wear, and improve The bearing capacity of the bearing.
Structural Pot Bearings Structural Bearing Pads Our structural bearing products are permanent, self-lubricated, and oil-less, which eliminates the need for regular upkeep. Manufactured from high-quality metals like bronze, stainless steel, aluminum, iron, and steel alloys, they provide unparalleled performance in harsh, corrosive conditions.
Plastic plain bearings are self-lubricating via two unique processes. Smearing systems – Smearing occurs when small amounts of lubricating media such as PTFE, silicone, graphite, or MOS2 are wiped into the surface micro-finish. Debris systems – Debris systems process when small particles of the polymer are removed during normal operations
