Fully Meets ANSI Standards
Manufactured Away Of SAE 1045 Steel
Black Oxide Treated
Induction Hardened Teeth
Extremely Durable
High Quality Sprocket
Double Pitch Chain Sprockets
Available for Double Pitch Chain with S or R rollers.
We offer a line-up for RS2040 – RF2160 with S rollers, and RF2040 – RF2100 with R rollers.
Chains that use S rollers build relationships almost every other tooth. Sprockets will have an extended life as chains engage with different teeth each time the rollers rotate (when actual number of teeth is odd).
Sprocket for Double Pitch Chain
As proven in the sketch, chain rollers use different teeth on every time of revolution when each roller skip one tooth and sprocket has odd number of teeth. This mechanism allows extension of sprocket life as less wear and abrasion.
S roller type chain can work well with regular roller chain sprocket with more than 30 teeth.

This 2042A16 sprocket is durable, exceeds in quality, and offers a long working life at an extremely great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 double pitch roller chain, possess 16 teeth, and fully meet all ANSI Requirements. Additionally, this sprocket includes a stock bore but we are able to supply the sprocket already bored out to nearly every requested bore size. Something that sets this 2042A16 sprocket aside from others is that it’s Black Oxide Finished, high temperature treated, and is manufactured using a top quality steel. Carrying out this with a sprocket makes it much more durable, perform to its best capabilities, and last much longer when compared to competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are normally in stock and at an extremely great price. For prices and availability please contact us and we will be happy to help you.
Features

Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are really durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller style, single duty sprockets are created to order and typically take anywhere from a few business days to some weeks to manufacture based upon our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets will be the same outside diameter and width as the single-pitch equivalent simply with a different tooth profile to permit proper seating of the chain. On also tooth-counts, these sprockets only build relationships the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any given tooth is engaged only on every other revolution which of program increases the sprocket life.
Carrier Roller Type
Carrier roller type dual pitch sprockets are cut with space cutters to allow the carrier roller to properly chair and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Single duty sprockets are manufactured to where every single tooth gets involved evenly on each revolution. This sprocket type has become obsolete in most applications but continues to be available.
When using dual pitch roller chain it is extremely recommended if not required to use a dual pitch sprocket. The reason being double pitch sprockets are produced with a particular tooth profile which allows for the roller to correctly seat and engage with the teeth of the sprocket. The above photo on the left may be the standard tooth profile and the photo on the right is the special dual pitch sprocket profile. As possible plainly see above, the double pitch sprockets tooth profile is certainly slightly deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failure to engage will lead to chain jumping and also excessive wear. Something important to note can be that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is certainly 31 or more you can make use of a standard roller chain sprocket. This rule does not connect with carrier roller style chains which where the roller diameter exceeds the sidebar elevation, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
