About Martin Roller Chain Sprocket, Bored-to-Size, Type B
The Martin type BS sprocket, also known as a bored-to-size sprocket, includes two setscrews and a keyway, and is suitable for use with the series 35 chain with a 3/8” pitch. This sprocket has been adapted for installation on the shaft without additional components. Made from high carbon steel, it has high strength and durability. This sprocket has a hub extension on one side to provide stability and allow for the use of a full-depth keyway and two standard set-screws to attach the sprocket onto a shaft. The options for this class of sprocket are: number of teeth from 9 to 112; outside diameter from 1.260” to 13.590”; stock bore size from 3/8” to 1-1/4”; length through bore from 3/4” to 1.00”; and approximate weight from 0.10 lbs to 6.50 lbs. The chain row width is 0.168” nominal. The keyway is on the centerline of the tooth. The following exceptions are present: the 9-tooth option with 3/8” shaft has no keyway and uses two (2) 1/4” setscrews; the 10-tooth option with 3/8” and 1/2” shaft has no keyway and uses two (2) 1/4” setscrews; the 10-tooth option with 5/8” shaft has the keyway is aligned with the setscrews at 90 degrees; the 11-tooth option with 3/8” and 1/2” shaft has no keyway and uses two (2) 1/4” setscrews; the 11-tooth option with 5/8” and 3/4” shaft has the keyway is aligned with the setscrews at 90 degrees; the 12-tooth option with 1/2” shaft has no keyway and uses two (2) 1/4” setscrews; the 12-tooth option with 3/4” shaft has the keyway aligned with the setscrews at 90 degrees; the 13- to 25-tooth options in the 1/2” shaft option have no keyway and use two (2) 1/4” setscrews at 90 degrees. With this series of sprockets, the hub diameters will vary to suit different bore sizes. All Martin sprockets meet or exceed ANSI standards.
