Sprockets for double pitch roller chains can be found in an individual or double-toothed design. Single-toothed sprockets for dual pitch roller chains possess the same behaviour as standard sprockets for roller chains in accordance to ISO 606. Due to the bigger chain pitch of double pitch roller chains you’ll be able to increase durability by toothing modifications.
Double-toothed sprockets are offered either in full or in two tooth steps. Full tooth guidelines are double-toothed so that only part of the the teeth is used effectively. The benefit is that whenever the chain is exchanged the so far unutilised tooth can be used after that, and the sprockets can stay in the system.
In order to increase the life cycle of a chain drive even more, sprockets can be produced with fifty percent tooth steps. With every rotation the chain joints move one tooth ahead in the meshing. This decreases the use of the chain and the tooth edges. This kind of toothing is frequently used when, due to the respective design, only minor deflections can be realised.
Our sprockets and plate sprockets are made of C 45, stainless steel, and special materials with a material strength 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 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 dual pitch roller chains are available in an individual 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 extremely durable, high-strength, and produced to high precision tolerances. Stock double pitch sprockets include regular roller and carrier roller style, solitary duty sprockets are made to order and typically take anywhere from a couple of business days to a few weeks to produce based upon our factory loads and sprocket specifics.
Standard Roller Type
Regular 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 every other tooth because there are two 
teeth per pitch. On odd tooth counts, any provided tooth is engaged just on 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 permit 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
Solitary duty sprockets are manufactured 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 double pitch roller chain it is highly recommended if not necessary to use a double pitch sprocket. The reason being dual pitch sprockets are manufactured with a special tooth profile which allows for the roller to properly seat and engage with one’s 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 double pitch sprockets tooth profile can be slightly deeper and cut differently to totally accept the double pitch chain roller. If using a standard sprocket, failing to engage will result in chain jumping and also excessive wear. Something important to note can be 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 guideline does not connect with carrier roller style chains which where the roller diameter exceeds the sidebar height, these chain sizes consist of C2042, C2052, C2062, C2062H, C2082H, C2102H, C2122H, and C2162H.
