Stainless Steel Sprocket, commonly made of stainless steel such as 201304. Stainless steel sprocket models: including non-standard sprockets (customized according to customer drawings) and standard sprockets (American and metric).
The size of the sprocket is determined based on the number of pitch and groove teeth. Stainless steel comes in various grades such as SUS304.201. The sprocket is selected based on installation dimensions, speed ratio, torque, and equipment usage.
The general principle for selecting the number of sprocket teeth is that 19 or more teeth are generally used for active sprockets that operate at medium to high speeds and under normal working conditions.
17 teeth are only used for small pitch drive sprockets.
23 teeth or more, recommended for situations with impact. When the speed ratio is low, using a sprocket with a high number of teeth can greatly reduce the rotation of the chain links, the tensile load on the chain, and the load on the bearings.

The tooth profile of a sprocket is similar to that of a gear, but its tooth profile is not conjugate, and its tooth profile has great flexibility. The tooth profile of the sprocket should have the following performance: ensuring that the chain is energy-efficient, smooth, and free to mesh in and out; Minimize the impact and contact stress when the chain link meshes with the sprocket as much as possible; Has the ability to accommodate the increase in chain link spacing due to wear and tear; Easy to process. The commonly used tooth shapes include: straight arc tooth shape and two arc tooth shape. The teeth on both sides of the shaft surface of the roller chain sprocket are circular arcs or straight lines to facilitate the meshing and disengagement of the chain links.
