Sprockets for dual pitch roller chains are available in an individual or double-toothed design. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as regular sprockets for roller chains in accordance to ISO 606. Because of the larger chain pitch of double pitch roller chains you’ll be able to increase strength by toothing modifications.

Double-toothed sprockets can be found either completely or in half tooth steps. Full tooth techniques are double-toothed to ensure that only part of the the teeth is used effectively. The advantage is that when the chain is exchanged the up to now unutilised tooth can be used after that, and the sprockets can stay in the system.
In order to boost the life cycle of a chain drive even more, sprockets can be manufactured with fifty percent tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This reduces the put on of the chain and the tooth edges. This sort of toothing is frequently used when, because of the respective design, only minor deflections could be realised.
Our sprockets and plate sprockets are made from C 45, stainless steel, and special materials with a material power of between 500 N/mm² and 600 N/mm². Apart from hardened toothing, we also supply surface area treated types.
Dual pitch roller chains are manufactured according to the particular order and customers’ specifications.
On demand we supply sprockets with:
Bore and grove
Tapped and pin holes for bore
Tapped and pin holes for bore upon pitch circle
Slot holes upon hub and hole circle

Our sprockets for double pitch roller chains are available in an individual or in a double-toothed version.

Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened metal 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 regular roller and carrier roller design, solitary duty sprockets are made to purchase and typically take from a few business days to some weeks to manufacture based upon our Double Pitch Chain Sprockets factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets are the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to allow proper seating of the chain. On even tooth-counts, these sprockets just engage with the chain on almost 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 permit the carrier roller to properly chair and build relationships each tooth. These sprockets could have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
Solitary duty sprockets are produced to where every tooth gets involved evenly on each revolution. This sprocket type is becoming obsolete generally in most applications but continues to be available.
When using dual pitch roller chain it is extremely recommended if not required to use a double pitch sprocket. The reason being dual pitch sprockets are manufactured with a particular tooth profile which allows for the roller to properly seat and engage with one’s teeth of the sprocket. The above picture on the left may be the standard tooth profile and the picture on the right is the special dual pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is certainly somewhat deeper and cut differently to totally accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will lead to chain jumping as well as excessive wear. Something important to note is definitely 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 guideline does not connect with carrier roller style chains which where the roller diameter exceeds the sidebar height, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
2042A16 SPROCKET WITH STOCK BORE
2042A16 Sprocket

This 2042A16 sprocket is durable, exceeds in quality, and will be offering an extended working life at a really great price! 2042A16 dual pitch sprockets are produced specifically for C2042 double pitch roller chain, possess 16 teeth, and completely meet all ANSI Requirements. Additionally, this sprocket includes a stock bore but we can supply the sprocket already bored out to almost any requested bore size. A thing that sets this 2042A16 sprocket aside from others is that it’s Black Oxide Finished, temperature treated, and is produced using a top quality steel. Doing this with a sprocket makes it much more durable, perform to its greatest capabilities, and last a lot longer when compared to competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are normally in stock and at a really great price. For pricing and availability please contact us and we’ll be happy to help you.

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 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 the teeth is odd).
Sprocket for Double Pitch Chain
As proven in the sketch, chain rollers work with 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 life as less use and abrasion.
S roller type chain could work well with standard roller chain sprocket with an increase of than 30 teeth.
