Double Pitch Chain Sprockets

Sprockets for double pitch roller chains are available in an individual or double-toothed design. Double Pitch Chain Sprockets Single-toothed sprockets for dual pitch roller chains possess the same behaviour as regular sprockets for roller chains in accordance 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 two tooth steps. Complete tooth actions are double-toothed to ensure that only part of the the teeth is used effectively. The benefit is that when the chain is definitely exchanged the up to now unutilised tooth can be used after that, 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 often used when, because of the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are constructed with 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 treated types.
Dual pitch roller chains are produced according to the respective order and customers’ specifications.
On ask for 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 can be found in a single 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 dark oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, one duty sprockets are made to purchase 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 will be the same outdoors diameter and width as the single-pitch equivalent simply with a different tooth profile to allow appropriate seating of the chain. On actually tooth-counts, these sprockets just build relationships the chain on almost every other tooth because there are two the teeth 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 dual pitch sprockets are cut with space cutters to permit the carrier roller to properly chair and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch comparative.
Single Duty Type
One duty sprockets are manufactured to where every 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 highly recommended if not necessary to use a double pitch sprocket. The reason being dual pitch sprockets are produced with a particular tooth profile which allows for the roller to correctly seat and build relationships the teeth of the sprocket. The above photo on the left may be the standard tooth profile and the photo on the right may be the special double pitch sprocket profile. As you can see above, the double pitch sprockets tooth profile can be somewhat deeper and cut differently to totally accept the dual pitch chain roller. If using a standard sprocket, failing to engage will lead to chain jumping as well as excessive wear. Something vital that you note is that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count is usually 31 or 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 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 offers a long working life at an extremely great price! 2042A16 double pitch sprockets are manufactured specifically for C2042 dual pitch roller chain, have 16 teeth, and completely meet all ANSI Criteria. Additionally, this sprocket includes a share bore but we are able to supply the sprocket currently bored out to nearly every requested bore size. A thing that sets this 2042A16 sprocket apart from others is that it’s Black Oxide Finished, temperature treated, and is produced using a top quality metal. Carrying out this with a sprocket makes it much more long lasting, perform to its best capabilities, and last much longer compared to the competition. Because of our sourcing experts, partners, and engineers, these sprockets are normally in share and at a really great price. For pricing and availability please e mail us and we’ll be happy to help 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 Dual 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 almost every other tooth. Sprockets could have an extended life as chains build relationships different teeth every time the rollers rotate (when actual number of the teeth is odd).
Sprocket for Dual 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 system allows extension of sprocket existence as less put on and abrasion.
S roller type chain could work well with regular roller chain sprocket with more than 30 teeth.
