Double single sprockets are precision machined steel spockets and run with two single chains. They are stocked in minimum plain bore, taper bushed and Martin Split Taper style. The minimum plain bores can be quickly modified for your specific application.

Material: Aluminum Chain Pitch: #40/ #41/ #420 Bolt Circle: 5-1/4" Bolt Holes: 5/16" (6) Bore: 4-9/16" Lightened design .245" thick for extra durability

This roller chain sprocket has a 3/4-inch pitch, fits size 60 chains, and is single strand with one set of teeth around its circumference for use with single strand chains. It is a Type B sprocket with a hub projection encircling the bore on one side, and both the hub and bore have fittings and tapering grooves to accommodate a split taper bushing that fits the diameter of the shaft. The teeth of the sprocket help prevent slipping and binding to avoid power loss in assemblies.

For use on series 60 chain, 3/4" pitch provides flexible mounting options Idler sprocket with ball bearings offer reduced friction for longer sprocket life and less drag on the system Can be used to change the direction of chain motion or to adjust chain tension Varying numbers of teeth and stock bore sizes offer deployment flexibility High carbon steel for strength and durability

The Martin double, also known as a duplex, type B sprocket is suitable for use with the series 80-2 chain with 1” 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.

The type A roller chain sprocket has the simplest structure, which is plain and without any extensions on both side. It offers a stable and secure attachment to the shaft. The type B and type C roller chain sprockets have one hub extensions on one or both 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.
