Cam Follower A cam follower uses a cam, usually a flat piece of tooled metal, and follower system to replicate a specific motion. As the cam is rotated, pressure is applied to the follower, which tracks the shape of the cam by its edge and translates the movement of the cam into a movement pattern. The cam follower operates on a very simple principle and can be applied to a wide number of tasks, because although basic, it is highly...more
Pneumatic Seals 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...more
Spherical Roller Bearing 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 roller bearing not only can absorb high degrees of angular deviation but generally higher operational speeds as well.Spherical roller bearings share a common basic design with straight and tapered roller bearings in that they consist of an inner ring, captive roller race, and outer ring. The main difference in the designs is in the roller set which consists of a double row of barrel shaped rollers typically held in a brass or stainless steel cage. This design allows the roller rows in a spherical roller bearing to run at different speeds, thereby enabling the bearing to absorb high levels of linear deviation. This feature effectively lends this design a combination of radial and thrust bearing...more
Plain Bearing 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....more

Vertical Turbine Pump 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, also known as "stages." A metal plate called shroud supports the vanes of the impeller in an open or semi-open impeller, whereas in an enclosed impeller, the shroud encloses the impeller vanes. The turbine pump also consists of a water intake point and a water discharge point.The turbine pump motor is usually placed above the water level, but submersible types are available depending on the requirement of the application. The total energy taken by the pump to move water from the resource, i.e., the supply tank, to the point of discharge is known as total head. The total head of a powerful turbine pump can exceed several hundred feet (over 70 meters).On operation, water enters the centre of the rotating impeller, which is known as the "eye" of the impeller. The pump shaft is a steel rod that transfers power...more
