Double Pitch Chain Sprockets

Sprockets for double pitch roller chains can be found in a single or double-toothed style. Single-toothed sprockets for dual pitch roller chains have the same behaviour as regular 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 two tooth steps. Complete tooth steps are double-toothed so that only part of the teeth is used effectively. The advantage 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 raise 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, because of the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made from 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 particular 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 upon pitch circle
Slot holes on 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 double pitch sprockets are produced out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and produced to high precision tolerances. Stock dual pitch sprockets include standard roller and carrier roller style, single duty sprockets are Double Pitch Chain Sprockets china created to order and typically take anywhere from a couple of business days to some weeks to manufacture based on our factory loads and sprocket specifics.
Standard Roller Type
Standard roller type sprockets are the same outside diameter and width as the single-pitch equivalent just with a different tooth profile to allow proper seating of the chain. On even 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 almost every other revolution which of program escalates the sprocket life.
Carrier Roller Type
Carrier roller type double pitch sprockets are cut with space cutters to allow the carrier roller to properly seat and engage with each tooth. These sprockets will have the same diameter as the ANSI single-pitch equivalent.
Single Duty Type
Single duty sprockets are produced to where every tooth gets involved evenly on every revolution. This sprocket type is becoming obsolete generally in most applications but is still available.
When using double pitch roller chain it really is extremely recommended if not necessary to use a double pitch sprocket. The reason being dual pitch sprockets are produced with a special tooth profile which allows for the roller to correctly seat and engage with one’s teeth of the sprocket. The above photo on the left is the standard tooth profile and the photo on the right is the special double pitch sprocket profile. As you can plainly see above, the double pitch sprockets tooth profile can be 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 certainly that with chain sizes C2040, C2050, C2060, C2060H, C2080H, C2100H, C2120H, and C2160H when the tooth count can be 31 or even more you can use a typical roller chain sprocket. This guideline does not apply to carrier roller design chains which where in fact the roller diameter exceeds the sidebar height, 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 an extended working life at a really great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 double pitch roller chain, have 16 teeth, and fully meet all ANSI Standards. Additionally, this sprocket has a share bore but we can supply the sprocket already bored out to almost any requested bore size. A thing that sets this 2042A16 sprocket aside from others is that it is Black Oxide Finished, warmth treated, and is produced using a high quality metal. Doing this with a sprocket makes it much more long lasting, perform to its greatest capabilities, and last a lot longer compared to the competition. Thanks to our sourcing experts, partners, and engineers, these sprockets are usually in stock and at a really great price. For prices and availability please contact us and we will be happy to help you.
Features

Fully Meets ANSI Standards
Manufactured Away 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 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 Dual Pitch Chain
As proven in the sketch, chain rollers use different teeth on every time of revolution when each roller skip one tooth and sprocket has odd number of teeth. This mechanism allows extension of sprocket lifestyle as less put on and abrasion.
S roller type chain could work well with standard roller chain sprocket with an increase of than 30 teeth.
