Pneumatic seals are any of a class of seals used in applications including rotary or reciprocating motions. They are often used in pneumatic cylinders and valves. Pneumatic seals do not work well under high pressure. Therefore, they are generally used in areas of lower pressure.Pneumatic seals require minimal lubrication when exposed to air in order to create a tight seal. Pneumatic seals may also be exposed to high operating speeds at which the...more
A spherical roller bearing featured two rows of inner roller elements, which are tapered towards its end much like a wine barrel. This type of bearing is self-aligning and typically used where high shock or misaligned loads are common. Spherical roller bearings are comparatively expensive but generally have a longer life span than other bearing types. They are also available as heavy-duty variants for use in high load applications. A spherical...more
A plain bearing is a simple mechanism consisting of two sliding components. This lightweight, compact and inexpensive bearing is widely used in many types of equipment and is sometimes referred to as a Babbitt, bushing, or journal bearing. A plain bearing can be used for three basic types of motion: linear, thrust, and journal. The basic types of plain bearings are bushing, integral or two-piece. The bearings may be composed of many types of materials.Plain bearings used for linear motion may consist of either a round bearing and shaft assembly or two corresponding surfaces that slide against each other. Thrust motion plain bearings allow rotation to take place between two parts while supporting an axial load. Journal motion bearings typically consist of a rotating shaft inside of a stationary bearing. A journal motion is the most common type of motion in which a plain bearing is utilized.A bushing type bearing is a separate piece that is fitted inside of a housing to provide a replaceable bearing surface. Bushings are generally the most common type of plain bearing application. An integral bearing is actually built into the piece of equipment for which it is being used. Integral...more
A turbine pump is a centrifugal pump that is mainly used to pump water from deep wells or other underground and man-made bodes of water to water distribution systems. A centrifugal pump consists of a pump shaft, a rotating device known as an impeller, and a motor or an engine. A turbine pump may consist of multiple semi-open or enclosed impellers,...more
