Sprockets for dual pitch roller chains are available in an individual or double-toothed style. Single-toothed sprockets for double pitch roller chains possess the same behaviour as standard sprockets for roller chains in accordance to ISO 606. Due to the larger chain pitch of double pitch roller chains it is possible to increase strength by toothing modifications.
Double-toothed sprockets are offered either in full or in two tooth steps. Full tooth measures are double-toothed to ensure that only part of the the teeth is used effectively. The advantage is that when the chain is definitely exchanged the up to now unutilised the teeth can be used then, and the sprockets can stay in the system.
In order to boost the life cycle of a chain drive a lot more, sprockets can be manufactured with half tooth steps. With every rotation the chain joints move one tooth forward in the meshing. This decreases the use of the chain and the tooth edges. This type of toothing is often used when, due to the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless, 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.
Double pitch roller chains are manufactured according to the respective order and customers’ specifications.
On request we supply sprockets with:
Bore and grove
Tapped and pin holes for bore
Tapped and pin holes for bore upon pitch circle
Slot holes on hub and hole circle
Our sprockets for dual pitch roller chains can be found in a single or in a double-toothed version.
Our in-stock standard double pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are really durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include standard roller and carrier roller style, one duty sprockets are made to purchase 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 just with a different tooth profile to allow appropriate seating of the chain. On actually tooth-counts, these sprockets just engage with the chain on almost every other tooth because there are two the teeth per pitch. On odd tooth counts, any provided tooth is engaged only on every other revolution which of program escalates 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 equivalent.
Single Duty Type
Solitary duty sprockets are produced to where every tooth gets engaged Double Pitch Chain Sprockets evenly on every revolution. This sprocket type has become obsolete generally in most applications but continues to be available.
When using dual pitch roller chain it really is highly recommended if not required to use a double pitch sprocket. The reason being double pitch sprockets are manufactured with a particular tooth profile which allows for the roller to correctly seat and build relationships one’s teeth of the sprocket. The above photo on the left is the regular tooth profile and the photo on the right may be the special dual pitch sprocket profile. As you can plainly see above, the dual 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 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 usually 31 or even more you can use a standard roller chain sprocket. This guideline does not apply to carrier roller design chains which where in fact the roller diameter exceeds the sidebar elevation, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
2042A16 SPROCKET WITH STOCK BORE
This 2042A16 sprocket is durable, exceeds in quality, and offers an extended working life at a really great price! 2042A16 double pitch sprockets are produced specifically for C2042 double pitch roller chain, have 16 teeth, and completely meet all ANSI Standards. Additionally, this sprocket includes a stock bore but we are able to supply the sprocket already bored out to almost any requested bore size. Something that sets this 2042A16 sprocket aside from others is that it is Black Oxide Finished, heat treated, and is manufactured using a high quality metal. Carrying out this with a sprocket helps it be much more long lasting, perform to its best capabilities, and last much longer when compared to competition. Because of our sourcing experts, partners, and engineers, these sprockets are usually in share and at an extremely great price. For prices and availability please e mail us and we’ll be happy to assist you.

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 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 work with different teeth on each time of revolution when each roller skip one tooth and sprocket has odd number 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 more than 30 teeth.
