Double Pitch Chain Sprockets

Sprockets for dual pitch Double Pitch Chain Sprockets china roller chains are available in an individual or double-toothed design. Single-toothed sprockets for double pitch roller chains have the same behaviour as standard sprockets for roller chains in accordance to ISO 606. Due to the bigger chain pitch of dual pitch roller chains it is possible to increase durability by toothing modifications.

Double-toothed sprockets can be found either in full or in half tooth steps. Complete tooth guidelines are double-toothed so that only a part of the teeth is used effectively. The benefit is that when the chain is certainly exchanged the so far unutilised tooth can be used then, and the sprockets can remain in the system.
In order to increase the life cycle of a chain drive even more, sprockets can be produced with half 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 type of toothing is frequently used when, due to the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are constructed with C 45, stainless steel, and special materials 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 manufactured 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 on hub and hole circle

Our sprockets for dual 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 dark 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, single duty sprockets are made to order and typically take from a couple of business days to some weeks to produce based upon our 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 permit correct seating of the chain. On actually tooth-counts, these sprockets just build relationships the chain on every other tooth because there are two tooth per pitch. On odd tooth counts, any provided tooth is engaged only on 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 build relationships each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
One duty sprockets are manufactured to where every single tooth gets involved evenly on every revolution. This sprocket type is becoming obsolete in most applications but continues to be available.
When using double pitch roller chain it is extremely recommended if not required to use a dual pitch sprocket. The reason being double pitch sprockets are produced with a special tooth profile which 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 is the special dual pitch sprocket profile. As you can see above, the dual pitch sprockets tooth profile is certainly slightly deeper and cut differently to fully accept the dual pitch chain roller. If utilizing a standard sprocket, failure to engage will lead to chain jumping along with excessive wear. Something vital that you note is certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is 31 or even more you can use a typical roller chain sprocket. This rule does not apply to carrier roller design chains which where in fact 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 a long working life at a really great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 dual pitch roller chain, possess 16 teeth, and fully meet all ANSI Standards. Additionally, this sprocket has 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’s Black Oxide Finished, heat treated, and is produced using a high quality metal. Performing this with a sprocket makes it much more durable, perform to its best capabilities, and last much longer when compared to competition. Because of our sourcing experts, partners, and engineers, these sprockets are normally in stock and at a really great price. For prices and availability please e mail us and we will be happy to assist you.
Features

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 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 build relationships every other tooth. Sprockets will have a longer life as chains engage with different teeth every time the rollers rotate (when actual number of the teeth is odd).
Sprocket for Dual Pitch Chain
As shown in the sketch, chain rollers work with different teeth on every time of revolution when each roller skip one tooth and sprocket has odd amount of teeth. This mechanism allows extension of sprocket life as less use and abrasion.
S roller type chain can work well with regular roller chain sprocket with an increase of than 30 teeth.
