Roller Chains Sprocket: 21 Teeth, 3/8" Pitch, 1/2" Bore Dia MPN:SNFB3521

Roller chains are efficient power transmission devices offering smooth rotation between driving and driven elements with minimum play for durable functioning. This 21 teeth roller chain sprocket delivers versatility in fitting across applications requiring precise alignment due to its small pitch dimensions. The 3/8 pitch and 1/2 bore diameter promote torque transfer capability with varied mounting options on shafts or couplings for reliable power transmission across diverse industries relying on robust operation such as food processing, mining equipment, and packaging machinery.
