Product description
The Martin dual, also known as a duplex, type B sprocket is ideal for use with the series 80-2 chain with 1” pitch for driver or driven sprocket applications. Varying amounts of teeth and pitch diameters offer application flexibility. Created from high carbon steel, it has high durability and strength. Multiple chain capability allows for more power at higher operational speeds with higher load capacity.

Type B sprockets have a hub extension on one side to provide stability, and invite for the use of full-depth keyways and standard setscrews to attach the sprocket. They can also accommodate a wide selection of shafts. The double design accepts two chains side-by-side.

The options because of this class of sprocket are: number of teeth from 10 to 95; outside diameter from 3.680 to 30.830”; share bore size from 1 to 1-1/2”; optimum bore size from 1-1/2 to 4”; hub diameter from 2-9/16 to 6”; size through bore from 2-3/4 to 4-1/4”; and approximate weight from 3.6 to 165 lb. The facial skin width (excluding the hub) is 1.710”. The chain row thickness is usually 0.557” nominal. Hubs with a diameter size of 2-9/16” possess a recessed groove for chain clearance. Optimum bores will accommodate regular keyseat and setscrew over keyseat. Slightly bigger bores are possible without keyseat, shallow keyseat, or setscrew at position to keyseat. All Martin sprockets fulfill or exceed ANSI specifications.

A sprocket is a wheel with tooth around the perimeter that meshes with a chain, track, or other perforated or indented materials. Unlike gears that mesh with another equipment, sprockets mesh with a chain, which then interacts with another sprocket. Gears can be utilized to transmit power around a part, based on how they fit together. Sprockets with chains just work in directly lines. Some common benefits of chain-drive systems include minimal slippage, a set ratio between rotating shafts, and versatility with many different chain attachments and sprocket material selections. An sprockets example of a power transmission program is a standard bicycle, that includes a sprocket and a chain to deliver power from the rider’s legs to the tires making the bike move.

Martin Sprocket & Equipment manufactures power transmitting and conveying items. The company was founded in 1951 and is certainly headquartered in Arlington, TX. Martin provides tools that meet American Nationwide Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.
