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 Dual Pitch Chain with S or R rollers.
We provide a line-up for RS2040 – RF2160 with S rollers, and RF2040 – RF2100 with R rollers.
Chains that make use of S rollers engage with every other tooth. Sprockets could have a longer life as chains engage with different teeth every time the rollers rotate (when actual number of the teeth is odd).
Sprocket for Dual Pitch Chain
As proven in the sketch, chain rollers use different teeth on each time of revolution when each roller skip one tooth and sprocket has odd quantity of teeth. This mechanism allows expansion of sprocket existence as less use 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 offers a long working life at a really great price! 2042A16 double pitch sprockets are produced specifically for C2042 double pitch roller chain, possess 16 teeth, and completely meet all ANSI Specifications. Additionally, this sprocket includes a stock bore but we can supply the sprocket currently bored out to nearly every requested bore size. A thing that sets this 2042A16 sprocket apart from others is that it is Black Oxide Finished, temperature treated, and is produced using a high quality metal. Doing this with a sprocket helps it be much more long lasting, perform to its best capabilities, and last much longer compared to the competition. Thanks to our sourcing experts, companions, and engineers, these sprockets are normally in stock and at a really great price. For prices and availability please contact us and we will be happy to assist you.
Features

Our in-stock standard dual pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with dark oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller design, single duty sprockets are created to order and typically take from a couple of business days to some 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 just with a different tooth profile to allow proper seating of the chain. On actually tooth-counts, these sprockets just engage with the chain on every other tooth because there are two teeth per pitch. On odd tooth counts, any provided tooth is engaged just on every other revolution which of course escalates the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to allow the carrier roller to properly chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are produced to where every single tooth gets involved evenly on every revolution. This sprocket type is becoming obsolete in most applications but continues to be available.
When using dual pitch roller chain it is extremely recommended if not necessary to use a dual pitch sprocket. This is because dual pitch sprockets are manufactured with a special tooth profile which allows for the roller to correctly seat and engage with one’s teeth of the sprocket. The above picture on the left is the standard tooth profile and the picture on the right may be the special dual pitch sprocket profile. As possible plainly see above, the double pitch sprockets tooth profile is usually somewhat deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failing to engage will lead to chain jumping as well as excessive wear. Something vital that you note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count can be 31 or more you can use a standard roller chain sprocket. This rule does not apply to carrier roller style chains which where the roller diameter exceeds the sidebar elevation, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
