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 make use of S rollers build relationships every other tooth. Sprockets could have an extended life as chains engage with different teeth each time the rollers rotate (when actual number of tooth is odd).
Sprocket for Dual 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 an increase of than 30 teeth.

This 2042A16 sprocket is durable, exceeds in quality, and will be offering a long working life at an extremely great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 dual pitch roller chain, have 16 teeth, and completely meet all ANSI Criteria. Additionally, this sprocket has a stock bore but we can supply the sprocket currently bored out to almost any requested bore size. Something that sets this 2042A16 sprocket aside from others is that it is Black Oxide Finished, temperature treated, and is produced using a top quality metal. Carrying out this with a sprocket makes it much more long lasting, perform to its greatest capabilities, and last a lot longer when compared to competition. Because of our sourcing experts, partners, and engineers, these sprockets are usually in stock and at an extremely great price. For prices and availability please e mail us and we’ll be happy to assist you.
Features

Our in-stock standard dual pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller style, single duty sprockets are created to order and typically take from a couple of business days to a few weeks to manufacture based on 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 appropriate seating of the chain. On also tooth-counts, these sprockets only engage with the chain on every other tooth because there are two teeth per pitch. On odd tooth counts, any provided 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 seat and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
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 generally in most applications but continues to be available.
When using dual pitch roller chain it is highly recommended if not required to use a double pitch sprocket. This is because double pitch sprockets are manufactured with a special tooth profile which allows for the roller to properly seat and engage with the teeth of the sprocket. The above photo on the left is the standard tooth profile and the picture on the right is the special dual pitch sprocket profile. As possible plainly see above, the double pitch sprockets tooth profile is somewhat deeper and cut differently to fully accept the double pitch chain roller. If using a standard sprocket, failing to engage will result in chain jumping and also excessive wear. Something important to note is that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or even more you can make use of a typical roller chain sprocket. This guideline does not apply to carrier roller design chains which where the roller diameter exceeds the sidebar elevation, these chain sizes include C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
