Fully Meets ANSI Standards
Manufactured Out 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 use S rollers build relationships every other tooth. Sprockets will have an extended life as chains engage with different teeth every time the rollers rotate (when actual number of the teeth is odd).
Sprocket for Double Pitch Chain
As demonstrated 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 system allows extension of sprocket life as less put on 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 a really great price! 2042A16 double pitch sprockets are produced specifically for C2042 double pitch roller chain, possess 16 teeth, and fully meet all ANSI Specifications. Additionally, this sprocket has a stock bore but we are able to supply the sprocket currently bored out to nearly every requested bore size. Something that sets this 2042A16 sprocket apart from others is that it is Black Oxide Finished, heat treated, and is manufactured using a top quality metal. Carrying out this with a sprocket helps it be much more durable, perform to its greatest capabilities, and last much longer compared to the competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are usually in stock and at an extremely great price. For pricing and availability please contact us and we will be happy to assist you.
Features

Our in-stock standard double pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with dark oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller design, single duty sprockets are created to purchase and typically take anywhere from a few business days to some weeks to manufacture based on our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets are 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 tooth per pitch. On odd tooth counts, any provided tooth is engaged just on almost every other revolution which of training course increases the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to permit the carrier roller to properly seat and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are produced to where every single tooth gets engaged 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 necessary to use a double pitch sprocket. The reason being dual pitch sprockets are produced with a special tooth profile that allows for the roller to correctly seat and engage with the teeth of the sprocket. The above picture on the left is the regular tooth profile and the photo on the right may be the special double pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile can be slightly deeper and cut differently to totally accept the double pitch chain roller. If utilizing a standard sprocket, failure to engage will result in chain jumping as well as 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 use a standard roller chain sprocket. This guideline 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.
