#35 (3/8") Pitch Sprockets
ANSI #35 sprockets are sized for 3/8 inch (9.525 mm) pitch roller chain: the industry-standard size for light-duty intermittent use, low torque applications applications. Our BlackStar #35 sprockets are precision-cut from medium carbon steel with a hardened tooth profile, available in tooth counts from 9 to 95 and three hub configurations (A-plate, B-hub, C-hub) for direct shaft mounting or bushing installation.
When To Use #35 Sprockets
#35 chain has a 3/8" pitch with 0.200" roller diameter. Working load capacity is approximately 480 lbs per strand, with average ultimate tensile strength of 2,100 lbs. This combination makes #35 ideal for:
- Industries: precision instruments, office equipment, vending machines, medical devices, small consumer machinery
- Common applications: paper handlers, ticket dispensers, ATMs, copy machines, light agricultural tools
- Replacement of existing #35 sprockets without changing chain specification
- New designs where engineering analysis specifies this ANSI size

How To Select The Right Sprocket
Three specifications drive sprocket selection for any chain drive:
1. Tooth Count
More teeth means smoother chain engagement and reduced wear per tooth, but increases overall diameter. As a rule of thumb: drive sprockets should have at least 17 teeth for high-speed applications, and at least 19 teeth for shock-loaded systems. Driven sprockets can go larger for speed reduction. We stock 9-95 tooth options for most pitches.
2. Hub Style
Three hub styles match different mounting needs:
- A-Plate: Flat sprocket, no integral hub, use with a bushing (QD or Taper-Lock) for tool-free shaft removal.
- B-Hub: Hub on one side of the sprocket, direct shaft mounting with set screws or keyway.
- C-Hub: Hubs on both sides, for higher torque transmission and longer engagement.
3. Bore Type
Plain stock bore lets you machine to a custom shaft size. Finished bore with keyway and set screws mounts directly. QD or Taper-Lock requires a matching bushing but allows fast field removal.
Chain & Component Compatibility
#35 sprockets pair with #35 ANSI standard roller chain. For multi-strand applications, you need a matching multi-strand sprocket: a #35-2 (double-strand) sprocket for #35-2 chain. Our Lynx chain line offers cottered and riveted variants in single, double, and triple strand configurations.
