#200 (2-1/2") Pitch Sprockets

ANSI #200 sprockets are sized for 2-1/2 inch (63.5 mm) pitch roller chain: the industry-standard size for extreme load, shock loading, high reliability requirements applications. Our BlackStar #200 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 #200 Sprockets

#200 chain has a 2-1/2" pitch with 1-9/16" roller diameter. Working load capacity is approximately 21,000 lbs per strand, with average ultimate tensile strength of 95,000 lbs. This combination makes #200 ideal for:

Industries: steel mills, cement plants, oil & gas, paper mills, major industrial machinery
Common applications: rolling mills, cement kilns, kiln drives, paper machine drives, draglines, port cranes
Replacement of existing #200 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

#200 sprockets pair with #200 ANSI standard roller chain. For multi-strand applications, you need a matching multi-strand sprocket: a #200-2 (double-strand) sprocket for #200-2 chain. Our Lynx chain line offers cottered and riveted variants in single, double, and triple strand configurations.

Frequently Asked Questions

How do I confirm my chain is #200 pitch?

Measure the distance from pin center to adjacent pin center along the chain, for #200, that distance is exactly 2-1/2" (63.5 mm). Roller diameter is 1-9/16". Most ANSI standard chain has the size number stamped on the outer link plates (200 or 200H for the heavy series).

Can I use #200H chain on #200 sprockets?

Yes, #200H (Heavy series) chain has identical pitch and pin geometry to standard #200 chain, but uses thicker side plates for higher tensile strength. It mates with standard #200 sprockets with no modifications required.

What's the difference between #200 and #200-2 sprockets?

#200-2 is the double-strand version: two parallel rows of teeth on a wider hub, designed to mate with #200-2 (double-strand) chain. Same pitch and tooth profile, but with double the load capacity. A single-strand #200 sprocket cannot drive double-strand chain: the strands need separate tooth rows.

How does sprocket wear affect chain life?

Worn sprockets accelerate chain wear by causing uneven load distribution across pins. If teeth show pointed, hooked, or asymmetric profiles, replace the sprocket, installing new chain on worn sprockets typically reduces chain life by 50% or more. A simple visual check: compare unloaded teeth against loaded teeth; significant asymmetry indicates time for replacement.

Do I need a bushing for a finished-bore sprocket?

No. Finished-bore sprockets have the bore machined to a specific shaft size with keyway and set screws, they mount directly to a matching shaft. Bushings (QD or Taper-Lock) are only needed with A-plate sprockets, which have a plain bore designed to fit a removable bushing for tool-free shaft removal.
