ANSI 50 13-Tooth Double-Strand Hardened-Tooth Sprocket, for Heavy-Load Logistics and Mining Conveying

The D50B13H American-standard taper-bush taper-bore sprocket is made of 45# steel with induction-hardened teeth (H), with 13 teeth, a double-strand (D) Type B structure, and fits American standard No. 50 roller chain. It is a durable transmission component within the North American industrial system for heavy-load, high-shock, and harsh conditions.

1. Hardened teeth, wear- and shock-resistant: Unlike ordinary soft-faced sprockets, the teeth are induction hardened (H), greatly raising tooth-surface hardness. In harsh conditions with severe shock or heavy dust such as mining and agricultural machinery, it effectively resists chain wear and multiplies service life.
2. American standard, globally universal: Produced strictly to the American standard No. 50 chain standard with accurate tooth form and pitch, it matches seamlessly with the globally common American standard No. 50 double-strand roller chain, ideal for equipment replacement and complete-machine export supply to the North American market.
3. Heavy-duty double strand + Type B hub: The double-strand (D) structure provides strong tensile and torque output; the Type B (single-side projecting hub) structure keeps adequate bore support length while saving space on the other side for a compact layout.
4. Matched with TB taper bush, quick installation and removal: Used with the American-standard TB taper bush, it grips with an 8° taper for very high coaxiality. For removal, simply unscrew the bolts, with no puller or cutting needed, making later servicing of heavy equipment very easy.

An industrial-grade rugged solution of "hardened teeth + heavy-duty double strand": Designed for high-shock, wear-prone scenarios, greatly reducing the frequency of downtime for part replacement.
A direct line to North American standards: From the No. 50 chain to the TB taper bush, the whole system is American standard and directly replaces brands such as Browning/Dodge, with no compatibility barrier.

Heavy-load logistics: Heavy-duty automated parking systems and escalator drive main shafts.
Mining and agricultural machinery: Agricultural machinery (harvester and tractor drives) and mining conveying equipment.
Oil and chemical: Oilfield pumping units and chemical agitating equipment (wear-resistant, withstands harsh environments).
