Floor Supports: Supporting members with vertical adjustments for leveling the conveyor.
Flow: The direction of travel of the product on the conveyor.
FPM: Feet per minute
Frame: The structure which supports the machinery components of a conveyor.

Gravity Conveyor: Roller or wheel conveyor over which objects are advanced manually by gravity.
Guard Rail: Members paralleling the path of a conveyor and limiting the objects or carriers to movement in a defined path.

Horsepower: (HP) A measure of the time rate of doing work defined as the equivalent of raising 33,000 pounds one foot in one minute. Electrically, one horsepower is 746 watts.
HZ: HERTZ - Electrical terminology, a unit of frequency equal to one cycle per second. Most common cycle time is 60 Hertz.

Incline Conveyor Length: Determined by the elevation change from infeed to discharge versus the degree of incline.
Inclined Conveyor: A conveyor transporting up a slope.
Infeed End: The end of a conveyor nearest the loading point.
Intermediate Bed: A middle section of conveyor not containing the drive or tail assemblies.

Motor: A machine which transforms electric energy into mechanical energy. Standard motors are dual voltage and operate at 1725 RPM.

Nose Roller: A small roller used on power belt curve conveyors, to reduce the gap at the transfer points.

Overall Length: (OAL) The dimension outside of pulley to outside of pulley including belting or lagging, of any conveyor lengthwise.
Overall Width: (OAW) The dimension outside to outside of frame rails.
Overhead Drive: A drive assembly mounted over a conveyor which allows clearance for the product.

Pop-Out Roller: A roller, normally placed on the ends of a belt conveyor, used to aid in transfer, and set in a wide groove to allow it to eject if an object comes between it and the belt.
Power Conveyor: Any type of conveyor which requires power to move its load.
Powered Feeder: A driven length of belt conveyor normally used to move product horizontally onto an incline conveyor.
Pressure Roller: A roller used for holding the driving belt in contact with the load carrying rollers in a belt driven live roller conveyor.
Pulley: A wheel, usually cylindrical, but polygonal in cross section with its centre bored for mounting on a shaft.
Push Button Station: An electrical device which operates a magnetic starter.
Pusher: A device, normally air powered, for diverting product 90 degrees from one conveyor line to another line, chute, etc.

Return Idler: A roller which supports the return run of the belt.
Roller: A round part free to revolve about its outer surface. The face may be straight, tapered or crowned. Rollers may also serve as the rolling support for the load being conveyed.
Roller Bed: A series of rollers used to support a conveying medium.
Roller Centres: The distance measured along the carrying run of a conveyor from the centre of one roller to the centre of the next roller.
Roller Conveyor: A series of rollers supported in a frame over which objects are advanced manually, by gravity or by power.

Shaft: A bar usually of steel, to support rotating parts or to transmit power.
Skate wheel Conveyor: A type of wheel conveyor making use of series of skate wheels mounted on common shafts or axles, or mounted on parallel spaced bars on individual axles.
Slider Bed: A stationary surface on which the carrying run of a belt conveyor slides.
Snub Idler: Any rollers used to increase the arc of contact between a belt and drive pulley.
Speed Reducer: A power transmission mechanism designed to provide a speed for the driven equipment less than that of the prime mover. They are generally totally enclosed to retain lubricant and prevent the entry of foreign material.
Support: Arrangement of members used to maintain the elevation or alignment of the conveyors. Supports can take the form of hangers, floor supports, or brackets and can be either stationary or portable.

Tail End: Usually the end of a conveyor nearest loading point.
Tail Pulley: A pulley mounted at the tail end of a conveyor, its purpose is to return the belt.
Take-Up: The assembly of the necessary structural and mechanical parts which provide the means to adjust the length of belt and chain to compensate for stretch, shrinkage or wear and to maintain proper tension.
Total Load: Amount of weight distributed over the entire length of a conveyor.
Traffic Cop: A mechanical or electrical mechanism to prevent collision of objects as they merge from two conveyor lines into a single line.
