When are ball bearings used?
Generally, a ball bearing is used when speed is important; a roller bearing is used more often when load is most important.
How splash lubrication system work?
In a lathe gearbox it is hard for different lubricating types to lubricate the gearbox so splash lubrication is the easiest way to lubricate it. Splash lubrication is a method of applying lubricant, to parts of a machine, or certain parts of an engine, teeth on the connecting-rod bearing caps are submerged in an oil container when it rotates. When the dippers emerge from the oil container, the oil is splashed onto the cylinders and pistons, lubricating them. This stage is repeated throughout the use of the lathe always properly lubricating the gearbox. Engines are normally lubricated using force feeding lubrication and splash lubrication. The force fed lubrication is used to keep the oil container full whenever the splash lubrication is being used. Normally the oil used in splash lubrication has to have a low viscosity because if the oil is too thick the tooth that dips into the oil container will either pick up a very small amount or pick up none at all.

What are the 5 kinds of lubrication systems and state clearly their application and how they function?
SPLASH The splash system is no longer used in automotive engines. It is widely used in small four-cycle engines for lawn mowers, outboard marine operation, and so on. In the splash lubricating system, oil is splashed up from the oil pan or oil trays in the lower part of the crankcase. The oil is thrown upward as droplets or fine mist and provides adequate lubrication to valve mechanisms, piston pins, cylinder walls, and piston rings. In the engine, dippers on the connecting-rod bearing caps enter the oil pan with each crankshaft revolution to produce the oil splash. A passage is drilled in each connecting rod from the dipper to the bearing to ensure lubrication. This system is too uncertain for automotive applications. One reason is that the level of oil in the crankcase will vary greatly the amount of lubrication received by the engine. A high level results in excess lubrication and oil consumption and a slightly low level results in inadequate lubrication and failure of the engine. A splash lubrication system is provided for motor vehicle transmissions and comprises an oil sump in the bottom portion of a case. The case accommodates a transmission shaft provided with gears which are immersed in the oil at least partly when the said oil sump is filled completely. In order to prevent the synchronizing mechanism from being blocked by cold and, consequently, very viscous oil in the presence of extremely low operating conditions--a condition which could lead to unsynchronized faulty gear shifting operations and, thus, damage to the transmission, the oil sump is connected with a cavity into which oil is drawn from the oil sump under low operating temperature conditions of the transmission. To this end, preferably, an expansion body is arranged in a cavity in the transmission shaft which contracts under cold conditions, and the cavity is connected. Combination Splash and Force Feed In a combination splash and force feed (fig.), oil is delivered to some parts by means of splashing and other parts through oil passages under pressure from the oil pump. The oil from the pump enters the oil galleries. From the oil galleries, it flows to the main bearings and camshaft bearings. The main bearings have oil-feed holes or grooves that feed oil into drilled passages in the crankshaft. The oil flows through these passages to the connecting rod bearings. From there, on some engines, it flows through holes drilled in the connecting rods to the piston-pin bearings. Cylinder walls are lubricated by splashing oil thrown off from the connecting-rod bearings. Some engines use small troughs under each connecting rod that are kept full by small nozzles which deliver oil under pressure from the oil pump. These oil nozzles deliver an increasingly heavy stream as speed increases. At very high speeds these oil streams are powerful enough to strike the dippers directly. This causes a much heavier splash so that adequate lubrication of the pistons and the connecting-rod bearings is provided at higher speeds. If a combination system is used on an overhead valve engine, the upper valve train is lubricated by pressure from the pump. FORCE FEED A somewhat more complete pressurization of lubrication is achieved in the force-feed lubrication system (fig.). Oil is forced by the oil pump from the crankcase to the main bearings and the camshaft bearings. Unlike the combination system the connecting-rod bearings are also fed oil under pressure from the pump. Oil passages are drilled in the crankshaft to lead oil to the connecting-rod bearings. The passages deliver oil from the main bearing journals to the rod bearing journals. In some engines, these opening are holes that line up once for every crankshaft revolution. In other engines, there are annular grooves in the main bearings through which oil can feed constantly into the hole in the crankshaft. The pressurized oil that lubricates the connecting- rod bearings goes on to lubricate the pistons and walls by squirting out through strategically drilled holes. This lubrication system is used in virtually all engines that are equipped with semi floating piston pins. Full Force Feed In a full force-feed lubrication system (fig.), the main bearings, rod bearings, camshaft bearings, and the complete valve mechanism are lubricated by oil under pressure. In addition, the full force-feed lubrication system provides lubrication under pressure to the pistons and the piston pins. This is accomplished by holes drilled the length of the connecting rod, creating an oil passage from the connecting rod bearing to the piston pin bearing. This passage not only feeds the piston pin bearings but also provides lubrication for the pistons and cylinder walls. This system is used in virtually all engines that are equipped with full-floating piston pins. kinds of Lubrication Differing widely in viscosity, specific gravity, vapor pressure, boiling point, and other properties, lubricants also offer a wide range of selection for the increasingly varied needs of modern industry. But whatever their derivation or properties, the purpose of lubricants is to replace dry friction with either thin-film or fluid-film friction, depending on the load, speed, or intermittent action of the moving parts. Thin-film lubrication, in which there is some contact between the moving parts, usually is specified where heavy loads are a factor. In fluid, or thick-film, lubrication a pressure film is formed between moving surfaces and keeps them completely apart. This type of lubrication cannot easily be maintained in high-speed machinery and therefore is used where reciprocating or oscillating conditions are moderate.
Why cross head bearing lubrication most difficult very important?
The force is always down wards, lubrication is a big problem. The relative motion between the x head pin and bearing will never allow to form a thin film lubrication as their relative motion is only for few degree and that too never in one direction
What is lubrication system?
Mist lubrication system is that, in which the lubrication of a bearing is done by the oil in the form of oil mist.

What makes a bearing go bad?
Heat, lack of lubrication, contamination of the lubricant such as water or dirt,entering the bearing, or carrying a heavier load than the bearing was designed to handle.
Why does a Tapered roller bearing turns blue?
Could be from lack of correct lubrication or not adjusted properly.
How much grease should be applied to a sealed bearing?
Only a thin layer of grease should be applied to a sealed bearing to ensure proper lubrication without causing excess buildup.
