Power transmission parts for Greenville and Hunt County
From a feed-room conveyor to a garden tiller or a go-kart, chain and sprocket drives keep things moving. Greenville Bearing Supply Inc. supplies roller chain, sprockets, couplings and reducers to Greenville, TX and the surrounding area from our Wesley Street shop (75402). Bring the old chain, sprocket or coupling and we'll help match it.
Power-transmission parts have to match precisely: pitch, tooth count, bore and keyway for sprockets, and size and style for couplings. We work from the old part or a part number, and when a number isn't familiar our team can cross-reference it with other sources.

Drive systems on Hunt County farms and in local shops
Chain and sprocket drives are everywhere in rural Texas: hay and feed equipment, conveyors, augers, tillers, post-hole diggers and trailers, along with go-karts, mini bikes and other small powersports builds. When a chain stretches or a sprocket's teeth hook, the drive loses power and wears everything around it.
If you're building or repairing a drive, bring the old components along. We can check the chain pitch, count sprocket teeth, and measure bores and keyways, then help match a replacement that runs true.
How to choose chain and sprockets
- Identify the chain number stamped on the link plates. In ANSI chain the leading digit(s) give the pitch in eighths of an inch, so #40 is 1/2-inch pitch and #50 is 5/8-inch.
- Count the sprocket teeth and note the bore size, keyway, and whether it's a stock-bore or finished-bore sprocket.
- Replace chain and sprockets together — a new chain on worn teeth wears out quickly.
- Keep shafts aligned and the chain lightly lubricated, with a little slack rather than tight tension.
- Choose couplings by shaft diameters, keyways and the horsepower or torque they must carry.

What does the number on roller chain mean?
In ANSI roller chain, the first digit or digits give the pitch (the distance between pins) in eighths of an inch. For example, #40 chain has a 1/2-inch pitch, #50 has a 5/8-inch pitch and #60 has a 3/4-inch pitch.
What do I need to bring to match a sprocket or coupling?
Bring the old part if you can. Otherwise note the chain number, tooth count, bore size and keyway for a sprocket, or the shaft diameters and style for a coupling.
