06B-2B 15-Tooth Double-Strand Taper-Bore Sprocket, for Light Industry, Textiles, and Logistics Conveying

The 06B-2B 15 European-standard taper-bore cast iron sprocket is made of HT250 (GG25) gray cast iron, with 15 teeth and a double-strand (2B) design that fits 06B small-pitch roller chain. It is built for light industrial and industrial equipment requiring high smoothness, low noise, and low-to-medium-speed heavy-load transmission.

1. Double-strand structure, double the capacity: Compared with a single-strand sprocket, the 2B double-strand structure paired with double-strand 06B chain greatly increases tensile strength and torque transmission in the same installation space; the load is shared more evenly across the two strands, effectively avoiding the breakage that single-strand chains are prone to.
2. Cast iron material, excellent vibration and noise damping: HT250 gray cast iron has excellent vibration-absorbing performance, effectively absorbing the impact and noise from chain meshing in operation. Cast iron also has some natural self-lubricating ability and good wear resistance, which is very suitable for textile, food, and other conditions with noise and cleanliness requirements.
3. Taper-bush quick mounting, high centering accuracy: The taper bore + taper bush installation structure uses 8° taper locking instead of a traditional straight-bore key fit, ensuring very high coaxiality and no runout at high speed; installation and removal need no hammering, making sprocket replacement very convenient.
4. Precision-milled teeth, constant transmission ratio: The tooth form is precision milled and meshes accurately with 06B roller chain, achieving high transmission efficiency of 95%~97% and a slip-free constant transmission ratio with very stable speed ratio.

The top choice for "quiet, smooth operation + strong capacity" in low-to-medium-speed drives: The double-strand cast iron design perfectly solves the high noise and strong vibration of traditional single-strand steel sprockets.
Zero-barrier maintenance: The taper-bush locking design lets end customers replace sprockets quickly even in tight spaces, greatly shortening downtime.

 Light industry and textiles: Textile machinery, dyeing equipment, and garment assembly lines (low noise, smooth).
Automation and logistics: Escalator drives, automated parking systems, and material conveyors.
Wood and food processing: Woodworking machinery and food packaging lines (dust-resistant, rust-proof).
