Description

ANSI #40 Roller Chain Sprocket — The Most Widely Used ANSI Chain Sprocket

The #40 at 1/2 inch (12.7mm) pitch is the single most specified ANSI roller chain sprocket size worldwide. It covers approximately 40% of all industrial chain drive applications from light packaging machinery to medium-duty conveyor systems. We supply #40 sprockets in simplex (#40), duplex (#40-2), and triplex (#40-3) with tooth counts from 9 to 120 in A-plate, B-hub, C-hub, taper-lock, and QD bushed configurations.

🛠 CNC Precision: AGMA quality tooth profiles. 0.025mm TIR bore. Broached keyways.

🏭 Widest Hub Range: A-plate through QD bushed — more mounting options than any other ANSI size.

✅ Material Options: 1045 steel, SS304, SS316, nylon, cast iron. Surface treatments: black oxide, zinc, zinc-nickel.

📈 Deepest Inventory: #40 is our highest-volume ANSI line with extensive stock across common tooth counts.

Compatibility

Chain: ANSI #40, #40-2, #40-3. Also compatible with #41 lightweight chain (same pitch, narrower width).

Not compatible with ISO 08B — different roller diameter (ANSI: 7.92mm vs ISO: 8.51mm).

Bore: Stock bore pilots. Finished bore up to ~40mm depending on tooth count.

Applications

Agriculture & Food: Feed augers, small conveyor drives, grain handling, packaging machinery.

General Manufacturing: Assembly line drives, palletisers, automated guided vehicles, material handling systems.

Reviews

“#40 is our standard across all packaging lines. Ever-Power’s quality is consistent batch to batch.” — Maintenance Mgr, Melbourne, Australia ★★★★★

“Ordered stainless #40 for our dairy conveyor. Electro-polished finish passed food safety audit.” — Plant Eng., Waikato, New Zealand ★★★★★

“Good value #40 sprockets. We’ve standardized across 3 plants. Dimensional fit is always spot on.” — Group Procurement, Chicago, USA ★★★★

“QD bushed #40 simplified our line changeovers. Sprocket swap in 15 minutes.” — Production Mgr, Dandenong, Australia ★★★★★

“Hardened teeth last noticeably longer than unhardened alternatives. Worth the investment.” — Reliability Eng., Jakarta, Indonesia ★★★★★

FAQ

#40 vs #41?

#41 is a lightweight version of #40 with the same pitch but narrower plates and no rollers (bushings only). #40 sprockets are compatible with #41 chain but #41 sprockets should only be used with #41 chain.

#40 vs ISO 08B?

Both 12.7mm pitch but ANSI #40 roller is 7.92mm while ISO 08B roller is 8.51mm. Not interchangeable.

Taper-lock available?

Yes. #40 taper-lock sprockets available across the full tooth count range for rapid installation.

Cast iron #40?

Yes. Cast iron #40 for low-speed, high-torque applications where vibration damping is needed.

MOQ?

One piece. #40 is our highest-volume line with extensive stock for rapid dispatch.
