How I reduced Ramsay to a blubbering wreck. Gordon Ramsay, the flamboyant celebrity chef, is famous for his hard man image and is known for tearing strips off anyone who crosses him in his kitchen. But it seems he has not always been so fearsome.
posted 09-04-2000 10:41 PM Many of our gearboxes contain C3 clearance bearings. The explaination I was given regarding this is that it is due to the high ambient temperatures of our region.My info says that C3 clearance were for use in applications where there is a temperature differential between the inner and outer races.Hence there is uneven thermal expansion resulting in closing up of the internal bearing clearance.his is because general equipment, most motors, pumps and gearboxes, do not maintain the high machining tolorances required by the use of a C2 or tighter bearing and does not require the loose tolorance of a C4 or higher due to either thermal expansion or location.I guess this would make a C3 the normal.
G rease is the most common type of lubricant used for rolling element bearings today. About 90 percent of all bearings are lubricated in this manner. It is important to select the right grease for specific requirements and to calculate the lubricant life cycle.n practice, only a few grams of grease are used for lubricating rolling element bearings and this quantity typically lasts a long time. An exact calculation of the grease service life is consequently of particular importance.
