About Sintered Products
What are Sintered Products?
Sintered products are produced by compacting metal powders into the required shape and subjecting them to a heat treatment process to form a continuous metal structure with fine pores to retain lubricating oil. They remain porous and can absorb upto 25 percent by volume of lubricating oil.
Why Self Lubricating Bearings?
At Rest :- Pores constituting 25% of the volume of the metal structure are impregnated with oil, and retain this oil till needed.
In Rotation :- In operation oil comes to the surface of the shaft and the shaft rotates virtually on a "cushion of oil"
When Shaft Stops :- When the shaft stops rotating, capillary action causes the pores to reabsorb the oil into the body of the bearing, till it is required again.
