12B Double-Single Sprockets for 2 Simplex DIN 8187 Roller Chains (B Series)
12B double-single sprockets are designed for a pair of 12B-1 (3/4″ × 7/16″) simplex roller chains of the so-called European series (B series), standardized to ISO 606 (DIN 8187).
Sprockets in the double-single design replace 2 simplex sprockets, simplifying installation, saving space on the shaft, and increasing transmission reliability. The shared hub also minimizes the risk of misalignment.
