Martin Roller Chain Sprocket, Reboreable, Type B Hub, Double Pitch Strand, 2052/C2052 Chain Size, 1.25" Pitch, 8 Teeth, 0.625" Bore Dia., 3.77" OD, 2.359375" Hub Dia., 0.343" Width

The Martin double-pitch, single-strand, Type B sprocket is suitable for use with the 2052/C2052 chain. With a 1 1/4-inch, double-pitch configuration, it is available in conveyor series for carrier rollers only. High carbon steel has high strength and durability. Type B sprockets with a hub extension on one side provides stability and allows for the use of a keyway and set screw to attach the sprocket onto a shaft. For carrier rollers, the conveyor series specifications include 8 to 30 teeth, pitch diameter from 3.266 to 11.958 inches, stock bore from 5/8 to one inch, recommended max bore size from 1 16/32 to 2 3/4 inch, hub diameter from 2 23/64 to 3 1/4 inch, length through bore from one to 1 1/4 inch, weight from 1.38 to 12.90 pounds. Face width is 0.343 inches nominal. For drives with 31 teeth or more, Martin recommends using standard sprockets with series C-2000 chains. Specially made double-pitch sprockets are recommended for use with a double-pitch chain. However, ANSI standard sprockets can be used provided they have at least 30 teeth. Since double-pitch chains engage every other tooth, they can be indexed for longer sprocket life. Indexing must be done manually on sprockets with an odd number of teeth. All Martin sprockets meet or exceed ANSI standards. Sprockets are 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 interact 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. Martin Sprocket & Gear started in 1951 and is in the machining, fabrication, forging, casting, and powered metal technology, and plastic injection molding of countless power transmission and conveying products for the global market.
