What is the difference between double pitch sprockets and other sprockets

The main difference between double-pitch sprockets and other sprockets is the pitch size and applicable scenarios:

Pitch difference
The pitch of the double-pitch sprocket is twice the standard pitch (for example, when the single-pitch sprocket pitch is 12.7mm, the pitch of the double-pitch sprocket is 25.4mm). ‌


Applicable scenarios
‌Single-pitch sprocket‌: Suitable for driving scenarios (such as engine power output), emphasizing high transmission efficiency and precise positioning. ‌

‌Double-pitch sprocket‌: Suitable for conveying scenarios (such as material transportation), with better buffering and load-bearing capabilities. ‌

Structural characteristics
The pin design of the double-pitch sprocket can better adapt to heavy load and high-speed transmission needs, while the single-pitch sprocket is well known for its inter-tooth clearance design and is suitable for precision transmission. ‌


Other sprocket types (such as active/driven sprockets, plastic sprockets, etc.) are mainly used in specific industry scenarios due to material and structure differences, and have no direct connection with double-pitch sprockets.
