Sprockets for dual pitch roller chains can be found in a single or double-toothed style. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as standard sprockets for roller chains according to ISO 606. Because of the larger chain pitch of dual pitch roller chains you’ll be able to increase durability by toothing modifications.

Double-toothed sprockets can be found either completely or in half tooth steps. Complete tooth techniques are double-toothed so that only a part of the the teeth is used effectively. The advantage is that whenever the chain is definitely exchanged the so far unutilised tooth can be used after that, and the sprockets can remain in the system.
In order to raise the life cycle of a chain drive even more, sprockets can be produced with fifty percent tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This decreases the wear of the chain and the tooth edges. This sort of toothing is often used when, due to the respective design, just minor deflections can 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. Aside from hardened toothing, we also supply surface treated types.
Dual pitch roller chains are manufactured according to the particular 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 are available in an individual or in a double-toothed version.

Our in-stock standard dual pitch sprockets are produced out of SAE-1045 case hardened metal 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 Double Pitch Chain Sprockets china carrier roller design, single duty sprockets are made to purchase and typically take from a couple of business days to a few 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 simply with a different tooth profile to permit proper seating of the chain. On even tooth-counts, these sprockets just engage with the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any given tooth is engaged only on every other revolution which of training course escalates the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to permit the carrier roller to properly chair and engage with each tooth. These sprockets could have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are manufactured to where every single tooth gets engaged evenly on each revolution. This sprocket type has become obsolete generally in most applications but is still available.
When using dual pitch roller chain it is extremely recommended if not necessary to use a dual pitch sprocket. The reason being double pitch sprockets are produced with a particular tooth profile which allows for the roller to correctly seat and engage with the teeth of the sprocket. The above picture on the left may be the standard tooth profile and the picture on the right may be the special double pitch sprocket profile. As possible plainly see above, the dual pitch sprockets tooth profile is definitely slightly deeper and cut differently to fully accept the double pitch chain roller. If using a standard sprocket, failure to engage will result in chain jumping in addition to excessive wear. Something important to note is usually that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is definitely 31 or 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 include 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, have 16 teeth, and fully meet all ANSI Standards. Additionally, this sprocket includes a share bore but we can supply the sprocket currently bored out to almost any requested bore size. A thing that sets this 2042A16 sprocket apart from others is that it is Black Oxide Finished, temperature treated, and is manufactured using a high quality steel. Carrying out this with a sprocket helps it be much more durable, perform to its greatest capabilities, and last a lot longer compared to the 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 contact us and we’ll be happy to assist you.

Extremely Durable
High Quality Sprocket
Double Pitch Chain Sprockets
Available for Double 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 will have an extended life as chains build relationships different teeth each time the rollers rotate (when actual number of the teeth is odd).
Sprocket for Dual Pitch Chain
As demonstrated in the sketch, chain rollers work with 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 existence as less use and abrasion.
S roller type chain could work well with regular roller chain sprocket with more than 30 teeth.
