The Martin stainless steel, type B sprocket is suitable for use with the series 40 chain with 1/2” pitch. Varying numbers of teeth and outside diameter options offer application flexibility. Made from stainless steel, it has excellent resistance to various types of corrosion, including rust and scaling; and it retains strength at high temperatures.
Type B sprockets have a hub extension on one side to provide stability, and allow for the use of a keyway and setscrew to attach the sprocket onto a shaft.
The options for this class of sprocket are: number of teeth from 10 to 60; outside diameter from 1.840” to 9.840”; stock bore size of 1/2” to 3/4”; maximum bore size from 3/4” to 2-3/8”; hub diameter from 1-1/4” to 3-1/2”; length through bore from 7/8” to 1.00”; and a weight from 0.28 lbs to 7.00 lbs. The tooth width is 0.168” nominal. Hubs with a diameter of 1-9/16” or smaller have a recessed groove for chain clearance. The maximum bore size will accommodate the standard keyseat and setscrew over keyseat. Slightly larger bores are possible with no keyseat, shallow keyseat, or setscrew at angle to keyseat. All Martin sprockets meet or exceed ANSI standards.
A sprocket is a wheel with teeth around the perimeter that meshes with a chain, track, or other perforated or indented material. Unlike gears that mesh with another gear, sprockets mesh with a chain, which then interacts with another sprocket. Gears can be used to transmit power around a corner, based on how they fit together. Sprockets with chains only work in straight lines. Some common benefits of chain-drive systems include minimal slippage, a fixed ratio between rotating shafts, and versatility with many different chain attachments and sprocket material selections. An example of a power transmission system is a standard bicycle, which has a sprocket and a chain to deliver power from the rider’s legs to the wheels making the bike move.
