Description

The double-strand sprocket 12 A2 - 21 teeth - with hub is a precisely manufactured transmission element designed for roller chains with the ASA 60-2 (3/4" x 1/2" DUPLEX) profile. It stands out due to its robust design made of high-quality C45 steel, which guarantees high mechanical strength and reliability even in more demanding operating conditions.

The design with a hub makes it significantly easier to precisely mount the sprocket onto a shaft and ensures the directional stability of the entire drive. This model, weighing 3.69 kg from the proven manufacturer CHIARAVALLI, is supplied without additional induction hardening of the teeth, allowing you to easily customize the bore and any modifications according to the specifics of your application.

Technical advantages and details

21 teeth and pitch circle diameter of 127.82 mm: Ensures smooth engagement and a precise gear ratio.
ASA 60-2 DUPLEX profile: Double-strand design dimensioned for transmitting higher torques and even load distribution.
Profile width of 34.6 mm: Provides sufficient contact surface for secure distribution of the roller chain's pulling forces.

During installation, we recommend ensuring precise alignment and leveling of the shafts to prevent uneven wear on the teeth. Proper chain tensioning and regular lubrication will maximize the service life of the entire drive system.
