Self Lubricating Bearing Manufacturers in India
Self-lubrication is characterized by the ability of the bearing to transfer trace amounts of material to the mating surfaces. This transfer process creates a film that provides lubrication along the length of the rail or shaft and reduces friction. Self-lubricating has several advantages over traditional lubricated bearings.
Self-lubrication keeps the friction between the bearing and the drive system constant and eliminates the need for additional grease or oil that can attract contaminants that destroy traditional bearings.
Transfer process: The transmission process is a continuous dynamic function of self-lubricating bearings throughout their operating life.
The first and most important step in this process is the break-in period. At this point, the first transfer of material to the joint surface takes place. The amount of bearing material contained during transfer depends on several factors such as application speed, load, and stroke length. The first transfer process is typically a series of 50100 strokes. Self-lubrication is most effective in the secondary and ongoing phases of the transfer.
What makes the system self-lubricating? The simple Frelon transfer process
Lubrication is an integral part of bearing material. Lubricant (usually oil or grease) has not been added to the original bearing design. Lubrication does not fail or become ineffective over time (lubricant aging). Lubricates the shaft surface evenly. The additional components do not increase the cost of the entire system. To be truly self-lubricating, the bearing system must function exactly as its name implies. It must provide its own lubrication over the life of the system and must not have an external source that facilitates lubrication over a period of time.

Common misconceptions of self-lubrication - While these systems may be temporarily “self-lubricating”, the lubricant will eventually be used and need to be replaced.
Common non self lubricating systems
Grease or oil must always be present in the metal contact between the rolling elements and the raceway surface. Without this external lubricant, the ball or roller would come into direct contact with the shaft or truck material, causing wear and corrugation damage. Many manufacturers are trying to overcome this design weakness by adding an oil-soaked seal to the edge of the bearing or housing. This approach can bring some benefits to the life of rolling bearings.
Oil Impregnated Bronze: Bronze bearings are very porous and the material is impregnated with light oil. Under optimal conditions, this oil is attracted to the bearing surface and forms a lubricating layer between the bearing and the shaft.
Graphite Plug Bronze: Graphite is an excellent solid lubricant commonly added to bronze bearings. Solid graphite plugs are usually inserted into holes in the base bronze material.

Igus materials are made from high-performance polymers developed by igus and are characterized by their special properties. Due to its special composition, it is extremely worn-resistant, robust, and self-lubricating. Their lifespan can be determined accurately. In addition, each iglidur material has individual properties and strengths suitable for special applications.
What is the Igridur material made of? All iglidur materials are composed of three components: base polymer, fiber and filler, and solid lubricant. There are a variety of iglidur materials, as universal materials cannot fulfill all tasks equally well. Each has a different configuration and different application areas for the three components.
Solid lubricants are embedded in millions of small chambers of durable, mostly fiber-reinforced materials. As it moves, the material releases a small amount of solid lubricant from these chambers. This is enough to properly lubricate the area in the immediate vicinity.
It also helps reduce the coefficient of friction of iglidur materials. It is not absolutely necessary for the function of the bearing, but it has a supportive effect. They are embedded in a small chamber and cannot be squeezed out. Thanks to
self-lubrication, maintenance can be minimized wherever the iglidur material is used. The built-in solid lubricant eliminates the need for regular relubrication and keeps the bearings free of dirt and dust.
