Knowledge Base Glossary
Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.
25 Glossary Terms Found
Cage Deformation
Improperly installed or dropped bearing.
Cage Pocket Wear
Heavy contact between the rollers and cage pocket surfaces caused by a bearing’s operating too loosely.
Caged Bearing
Similar to a full complement bearing, except that there are fewer rollers, allowing room for the cage.
Carbonization
The reduction of a material to carbon.
Centrifugal Pump
A type of pump which relies on the rotation of an impeller to generate pressure and cause flow.
CEVA
Customer Economic Value Add -- a methodology that uses global best practices and experience to explore customer logistics and purchasing processes. This information, combined with other surveyed data, enables BDI to formulate a CEVA report indicating potential cost savings and productivity enhancements.
Closed-End Bearing
A drawn cup bearing where one end of the cup has a solid face, which fully encloses that end of the bearing. This allows the housing to be through bored (straight housing). The closed end of the installed bearing seals the housing.
Coefficient of Friction
The ratio of the force that maintains contact between an object and a surface and the frictional force that resists the motion of the object.
Cohesion
The molecular attraction between grease particles that causes them to stick together. This attraction contributes to its resistance to flow.
Combined Load
Both radial and thrust loads applied to the same bearing at one time.
Compound
Mixtures of rubber, plastics and other materials that are used to form the body of the belt.
Compression Packing
A deformable material used to prevent or control the passage of a pressurized fluid between surfaces that move in relation to each other.
Conrad Deep-Groove Ball Bearing
Standard single-row deep-groove bearing. Also referred to as a radial ball bearing.
Consignment
An inventory management strategy where supplier-owned material is stored on the client’s premises.
Continuous Operating Temperature (COT)
Actual operating temperature of service.
conveyor
A conveyor is a system of mechanical handling devices that moves materials from one location to another. Conveyors are especially useful in applications involving the transportation of heavy or bulky materials.
Corrosion
A chemical attack on metals by acids, alkalies, oxygen, chlorine, sulfur or other chemicals. This is distinct from metal destruction by wear and may be evident by either discoloration or pitting.
Corrosion Inhibitor
An ingredient added to packing, which decreases or eliminates the possibility of galvanic corrosion in the stuffing box. Corrosion inhibitors may be classified as either passive or active.
Cracking
A sharp break or fissure in the surface, generally due to excessive strain.
Crib Crawl
An exercise that takes place at the customer plant level, where representatives from a distributor such as BDI "poke through inventory in search of clues to wasteful spending."
Cross-Section
1) The view of a part as if it were cut to show its internal structure. 2) The distance between the shaft or stem surface and the bore of a stuffing box. 3) The shape of a packing ring at a cut. A packing ring could have a square, rectangular, or round cross-section.
Cycle and Adjust Procedure
A procedure used to consolidate a packing set after it has been installed in a stuffing box. This procedure helps to reduce the amount of gland load relaxation that occurs after the valve has been put into service.
Cylinder Bore
The internal diameter of the cylinder.
Cylinder Double Rod
A cylinder with a piston rod extending from each end.
Cylinder Single Rod
A cylinder with a piston rod extending from one end.
