Sprockets for double pitch roller chains are available in a single or double-toothed style. Single-toothed sprockets for double pitch roller chains have the same behaviour as regular sprockets for roller chains according to ISO 606. Due to the larger chain pitch of double pitch roller chains you’ll be able to increase toughness by toothing modifications.

Double-toothed sprockets are Double Pitch Chain Sprockets china offered either in full or in two tooth steps. Complete tooth measures are double-toothed to ensure that only part of the the teeth is used effectively. The advantage is that when the chain is exchanged the up to now unutilised teeth can be used then, and the sprockets can stay in the system.
In order to increase 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 forward in the meshing. This decreases the wear of the chain and the tooth edges. This type of toothing is frequently used when, because of the respective design, just minor deflections could be realised.
Our sprockets and plate sprockets are made from C 45, stainless, 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.
Dual pitch roller chains are manufactured according to the respective 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 on pitch circle
Slot holes on hub and hole circle

Our sprockets for double 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 black oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller design, one duty sprockets are made to order and typically take anywhere from a couple of business days to a few weeks to manufacture based upon our factory loads and sprocket specifics.
Standard Roller Type
Regular roller type sprockets are the same outside diameter and width as the single-pitch equivalent just with a different tooth profile to permit appropriate seating of the chain. On also tooth-counts, these sprockets just engage with the chain on almost 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 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 comparative.
Single Duty Type
One duty sprockets are produced to where every single tooth gets engaged evenly on each revolution. This sprocket type is becoming obsolete generally in most applications but continues to be available.
When using double pitch roller chain it is extremely recommended if not necessary 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 build relationships one’s 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 double pitch sprocket profile. As you can plainly see above, the dual pitch sprockets tooth profile is definitely somewhat deeper and cut differently to fully accept the dual pitch chain roller. If using a standard sprocket, failure to engage will lead to chain jumping and also 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 definitely 31 or even more you can make use of a typical roller chain sprocket. This rule does not connect with 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 offers an extended working life at a really great price! 2042A16 dual pitch sprockets are manufactured specifically for C2042 double pitch roller chain, possess 16 teeth, and fully meet all ANSI Specifications. 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 aside from others is that it’s Black Oxide Finished, heat treated, and is manufactured 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, companions, and engineers, these sprockets are normally in stock and at a really great price. For prices and availability please e mail us and we’ll be happy to help you.

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 almost every other tooth. Sprockets could have an extended life as chains build relationships different teeth each time the rollers rotate (when actual number of tooth is odd).
Sprocket for Double Pitch Chain
As demonstrated in the sketch, chain rollers work with different teeth on each time of revolution when each roller skip one tooth and sprocket has odd amount of teeth. This system allows expansion 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.
