n: Composed by several balls installed in the cone bearing and tray bath in the surface of cone axis. Used for sustaining radial reacting force of cone and part of axial force. Also can lock the cone and make sure it not fall off from the cone.

n: liquid placed in a container and held at a controlled temperature to regulate the temperature of any system placed in it or passing through it.

n: a metal strip inserted into a system to monitor corrosion rate and to indicate corrosion inhibitor effectiveness. corrosion fatigue n: metal fatigue concentrated in corrosion pits. See fatigue.

a representative piece of metal cut to a specific size and shape that is immersed in a test bath of placed in the flow stream to enable an estimation of the active corrosion occurring in a given set of conditions.

n: a type of lubrication in highspeed chain-and-sprocket drives in which a portion of the chain passes through an oil bath (sump),which coats all of the chain on each revolution to lubricate it.

n: a kinds of method that solves the filter cake adhere sticking.

n: on an engine, a canister that has a relatively small amount of lubricating oil in the bottom and which filters air entering an engine. The running engine draws air through the cleaner, where the air passes through an element and over the oil bath. Dust and dirt particles in the intake air are removed by the element and by the oil bath.

n: see oil-bath air cleaner. oil-bath reservoir n: in rotary table assemblies, a compartment in the base of the rotary table assembly that contains oil of a specified weight and viscosity and through which parts of the assembly move to be lubricated.

n: in a chain-andsprocket drive, a type of oil bath lubrication in which the chain itself does not pass through the sump, but one or two disks rotating with the sprocket pick up oil from the sump and sling it against a plate, which then feeds it to the top of the lower span. Compare drip lubrication, pressure lubrication.

n: a hollow cylindrical device installed around the swivels rotating stem that absorbs the stems rotation and helps form an oil seal between the stem and the oil-bath reservoirs inside the swivel.

n: A kind of liner that can decrease the wear and tear ,which be fixed on the out surface of the drilling string.

n: see oil-bath air cleanel:
