Oilite Sintered Bronze Flanged Sleeve Bearing FF-1202-4 1" ID x 1-1/4" OD x 3/4" L
Oil cushioned Oilite Sintered Bearings are fabricated from metal powders and contain approximately 18 percent oil (by volume). This vacuum impregnated oil supplements the strong, pure bronze structure and forms a hydraulic cushion to absorb unusual shocks and impacts, allowing the bearing to carry heavy loads. Self-lubricating Oilite bearings are separated from the shaft by a protective film of oil. The oil is supplied through thousands of interconnected, oil impregnated pores. Oil rises to the bearing surface when the shaft is in motion and is reabsorbed by the bearing through capillary action when the shaft is idle.

Sleeve bearings, also called journal or plain bearings, are used to constrain, guide or reduce friction in rotary or linear applications. These bearings don't roll like balls or rollers but slide. They require proper lubrication to reduce friction and consequently wear. Sleeve bearings are most commonly used in computing peripherals.
The material for the sleeve bearings can be bronze, beryllium copper or other similar hard metals that are pressed into porous forms by powder metallurgy. They are in the form of thick cylinders saturated with oil. They are low friction bearings used for heavy load applications.
Sleeve bearings operate on the principle that the rod fitting within the shaft rests upon a very thin layer of lubricant. The rod must not make any contact with the sleeve and operate silently. Lubrication in this type is essential or else the sleeve will wear away in no time. The plain bearings may fail due to wear, evaporation of the lubricant or the absence or thickening of the lubricant.
