As shown in the figure, when each roller skips a tooth, and the number of sprocket teeth is odd, the chain roller uses different teeth each time it rotates. The mechanism can prolong the service life of the sprocket and reduce wear.
S-type roller chains can be used with more than 30 standard roller chain sprockets with upper teeth.
Standard roller size C2040-C2160H
The roller and inside diameter is the same for these dimensions as the single-pitch version. But the stadium is twice as big (hence the name "double court"). Due to different pitches, the sprocket's pressure angle differs from the single-pitch version. Therefore, for chains with 30 teeth or less, a "double pitch sprocket" must be used for "double pitch chain." For chains with 31 teeth and more, double-pitch chains can use any standard single-pitch sprocket without any operational defects.
For example, the C2060H chain will mesh correctly with the 60B33 sprocket. However, the same chain cannot mesh with the 60B17 sprocket; In this case, the 2060B17 sprocket must be used.
It should be noted that the standard roller double-pitch sprocket is double-loaded, which means that there are two teeth per pitch. This means that enough teeth are half of the actual number of teeth.
Large coil size C2042-C2162H
Large roller chains cannot run on a single-pitch equivalent; For example, the C2042 chain cannot mesh with the 40B15 sprocket. Because the roller is more critical, it will not be correctly "seated" in the sprocket teeth. Therefore, a specific sprocket of size C2042-C2162H must be ordered.

What is the double pitch chain used for?
The double-pitch conveyor chain series is ideal for light to medium material handling applications. These chains are similar to standard chains, except that the plates are straight, and the pitch is twice that of standard chains.
Sprocket type
Two basic types of sprockets are double pitch and single load. The double-pitch sprocket has two teeth per pitch, while the single-load sprocket has one tooth per pitch. This means that the single-load sprocket is twice as large as the double-load sprocket.
Single load
The double-pitch chain wheel is a standard chain with a double pitch. These sprockets share the same pitch and branch parameters as standard 40 chains but are designed with a larger pitch. Large spacing helps with accessories such as crossbars and mesh belts. These sprockets are also used for transportation.
These sprockets are alternately manufactured with teeth to engage with the chain during each rotation. There are three basic types: single load type, one tooth per pitch; Double load type, with two teeth per chain pitch. This type of sprocket can be mounted on a shaft without a key.
Double responsibility system
The double-load pitch sprocket has twice as many teeth as the single-load sprocket. They are designed for long pitch chains. The double-load sprocket is similar in appearance to the hunting sprocket but has more teeth. They advanced half a ball per turn. In addition, the double-load sprocket provides twice the number of contacts and twice the life.
When selecting a sprocket, it is essential to determine the pitch of the chain and the diameter of the sprocket. Pitch diameter is the bending distance between the tooth center and the adjacent tooth center. Face width refers to the space through the thinnest part of the sprocket. The surface width is usually between the maximum and minimum values to prevent friction and ensure correct chain engagement. Another essential consideration is installing the system. Some hubs have unique mounting options for sprockets and chains.
Spur gear
Double-pitch sprocket spur gear is a standard power transmission gear. They are usually made of metal and match the ANSI chain pitch. They are used in pairs to reduce the speed of the chain. A single sprocket has no teeth that mesh with the teeth of the meshing gear. Sprockets are usually stainless steel and have extremely high hardness, temperature, and corrosion resistance.
These sprockets come in many different sizes. The minimum value is 8 mm, and the maximum value is 14 mm. Some are flanged. Single-pitch and double-pitch sprockets have various finishing holes and tooth shapes.
KANA Standard
KANA standard double-pitch sprockets are available in different sizes and shapes. KANA standard sprocket is a double-pitch roller sprocket. Its teeth are evenly spaced. KANA standard double-pitch sprocket is widely used in industrial applications.
These sprockets meet the requirements of British and American standards. They have a variety of standard spacing, including 1/4 inch, 1/2 inch, and 3/4 inch. Other sizes and pitch combinations are available, as well as unique products made of cast iron or gray cast iron.
Number of teeth
Double-pitch sprockets are used in applications where the chain has two teeth per revolution. They are made of the same high-quality raw material, C45, as are single, double sprockets. Operating conditions determine their maximum inside diameters. The actual inside diameter will be based on the chain's general mechanical design and the key's tightness.
There are two types of double-pitch sprockets, R-type and S-type. The R-type sprocket has a fixed number of teeth, while the S-type sprocket has a variable number of teeth. The number of teeth determines whether the sprocket is suitable.
shape
The double-pitch sprocket shape is ideal for applications using chain drives. This sprocket type is commonly used in conveyors, agricultural equipment, and power transmission equipment. In some applications, it is more efficient than belt drives. It is also used for bicycles and motorcycles.
There are two basic types of sprockets: double pitch and single pitch. The double-pitch sprocket has teeth on both sides and flanges on the top. Single-pitch and double-pitch sprockets are similar to each other. The shape of double-pitch sprockets allows the pins to fall into each gap and is typically used in conveyor systems.
size
A double-pitch chain requires a sprocket with an odd number of teeth. This reduces the number of times the chain contacts the sprocket. When selecting the sprocket size, remember that the sprocket will be secured to the crankshaft using ANSI standard-size keyways.
When determining the size of the double-pitch sprocket, the number of teeth on the sprocket can be calculated. The number of teeth is the simplest way to measure the size, but you can also use a caliper to measure the size of the inner diameter. This will also help you determine if the sprocket is worn.
