About Martin Roller Chain Sprocket, Reboreable, Type A
The Martin metric type A sprocket is suitable for use with series ISO 16B-1/metric 80 chain with 25.40 mm (1.00”) pitch. This sprocket has a narrow profile and no hub extension, and is easily adaptable for bushings, bearings, and sleeves. Varying numbers of teeth, pitch diameter, and stock bore size offer application flexibility. Made from high carbon steel, it has high strength and durability. The chain data for this class of sprockets is BS 228/15, ISO 16B-1; pitch is 25.40 mm (1.00”); roller diameter is 15.88 mm (0.625”); roller width is 17.02 mm (0.670”); and tensile strength is 4,310 kg (9,500 lbs.). The options for this class of sprocket are: number of teeth from 14 to 40; pitch diameter from 90.16 mm to 921.81 mm; stock bore size of 14 mm to 40 mm; and approximate weight from 0.82 kg to 76.36 kg. The tooth width is 16.18 mm (0.637”) nominal. Maximum bores will accommodate 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. Martin Sprocket & Gear manufactures power transmission and conveying products. The company was founded in 1951 and is headquartered in Arlington, TX. Martin provides tools that meet ANSI, NAS and DIN standards.
