Sprockets for double 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. Due to the larger chain pitch of dual pitch roller chains you’ll be able to increase toughness by toothing modifications.

Double-toothed sprockets are offered either in full or in half tooth steps. Full tooth methods are double-toothed to ensure that only part of the teeth is used effectively. The benefit is that Double Pitch Chain Sprockets whenever the chain is certainly exchanged the so far unutilised teeth can be used then, and the sprockets can remain in the system.
In order to raise the life cycle of a chain drive a lot more, sprockets can be produced with fifty percent tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This reduces the put on of the chain and the tooth edges. This kind of toothing is often used when, because of the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made from C 45, stainless, and special components with a material strength of between 500 N/mm² and 600 N/mm². Aside from hardened toothing, we also supply surface area treated types.
Double pitch roller chains are produced according to the respective 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 on pitch circle
Slot holes upon hub and hole circle

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

Our in-stock standard dual 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 produced to high precision tolerances. Stock dual pitch sprockets include regular roller and carrier roller style, solitary duty sprockets are created to purchase and typically take from a few business days to a few weeks to produce based on our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets will be the same outdoors diameter and width as the single-pitch equivalent just with a different tooth profile to permit appropriate seating of the chain. On actually tooth-counts, these sprockets only engage with the chain on every other tooth because there are two teeth per pitch. On odd tooth counts, any given tooth is engaged only on almost every other revolution which of course increases 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
One duty sprockets are produced to where every tooth gets engaged evenly on every revolution. This sprocket type has become obsolete in most applications but continues to be available.
When using dual pitch roller chain it is highly recommended if not required to use a double pitch sprocket. The reason being dual pitch sprockets are manufactured with a particular 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 standard 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 totally accept the double pitch chain roller. If utilizing a standard sprocket, failing to engage will lead to chain jumping in addition to 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 usually 31 or even more you can use a typical roller chain sprocket. This guideline 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.
2042A16 SPROCKET WITH STOCK BORE
2042A16 Sprocket

This 2042A16 sprocket is durable, exceeds in quality, and will be offering an extended working life at an extremely great price! 2042A16 double pitch sprockets are manufactured specifically for C2042 double pitch roller chain, have 16 teeth, and completely meet all ANSI Requirements. Additionally, this sprocket includes a share bore but we are able to 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’s Black Oxide Finished, high temperature treated, and is produced using a top quality metal.

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 build relationships almost every other tooth. Sprockets will have an extended life as chains engage with different teeth every time the rollers rotate (when actual number of teeth is odd).
Sprocket for Double Pitch Chain
As demonstrated in the sketch, chain rollers use 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 wear and abrasion.
S roller type chain can work well with regular roller chain sprocket with more than 30 teeth.
