Martin Roller Chain Sprocket, Reboreable, Type B Hub, Double Strand, 06B Chain Size, 9.525mm Pitch, 38 Teeth, 16mm Bore Dia., 120.66mm OD, 90mm Hub Dia., 15.44mm Width

• For use with 06B-2 chain, 9.525 mm pitch, meets ISO metric standards
• Double type B sprocket offers a stable and secure attachment to the shaft, and can be modified as needed to suit applications requiring two chains
• Shaft diameter options range from 10 to 25 mm for a variety of applications
• Varying numbers of teeth and pitch diameter sizes offer application flexibility
• High carbon steel for strength and durability

The Martin metric double, also known as a duplex, type B sprocket is suitable for use with the series ISO 06B-2/metric 35-2 chain with a 9.525 mm (0.375”) pitch for driver or driven sprocket applications. Varying numbers of teeth and pitch diameters offer application flexibility. Made from high carbon steel, it has high strength and durability. Multiple chain capability allows for more power at higher operational speeds with greater load capacity.

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

The chain data for this class of sprockets is BS 228/3, ISO 06B-2; pitch is 9.53 mm (0.375”); roller diameter: 6.35 mm (0.250”); roller width is 5.72 mm (0.225”); and tensile strength is 1,730 kg (3,800 lb.).

The opt ions for this class of sprocket are: number of teeth from 12 to 114; pitch diameter from 36.80 to 345.68 mm; stock bore size from 10 to 25 mm; maximum bore size from 16 to 62 mm; hub diameter from 25 to 95 mm; length through bore from 25 to 38 mm; and approximate weight from 0.16 to 11.12 kg. The face width (not including the hub) is 15.44 mm (1.758”). The chain row thickness is 5.20 mm (0.205”) 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. Sprocket s 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 American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.
