Descrição
Hangzhou Ever-Power Sprocket Co., Ltd.
If a European machine runs DIN 8187 chain and you install an ANSI sprocket — it will fit on the shaft but the chain will not run correctly. Understanding this distinction is what this page is built around.
The Specification Error That Looks Right Until the Machine Runs
A purchasing manager ordering a replacement #40-equivalent stainless steel sprocket for a European-manufactured food conveyor might reasonably specify “12.7 mm pitch stainless sprocket” — and receive an ANSI 40 unit that fits the shaft bore, looks dimensionally correct sitting on the desk, and mounts without obstruction. The problem appears within the first operating hour: the smaller 8.51 mm roller of the DIN 8187 (08B) chain does not seat correctly in the 7.92 mm-roller-profile tooth form of the ANSI 40 sprocket. The chain rides high on the tooth tips, generates noise, and wears at a rate several times higher than normal. Within weeks, both sprocket and chain may require replacement. The Roda dentada Ever-Power em aço inoxidável, padrão europeu is machined specifically to DIN 8187 / ISO 606 tooth geometry — verified against DIN 8187 chain gauge sets, not just drawings — ensuring correct seating and full-life performance on European-standard chain drives.
DIN 8187 vs. ANSI B29.1 — The Dimensional Differences That Matter
Both standards use the same pitch values but differ in roller diameter and inner width — the two dimensions that directly determine tooth form geometry. At every common pitch, the DIN roller is larger than the ANSI roller, requiring a different seating radius in the sprocket tooth pocket. This is why ANSI and DIN sprockets are not interchangeable even when pitch matches.
| BS/DIN Chain | Passo (mm) | DIN Roller Dia. | ANSI Equiv. | ANSI Roller Dia. |
|---|---|---|---|---|
| 06B | 9.525 | 6.35 mm | ANSI 35 | 5.08 mm ❌ |
| 08B | 12.7 | 8.51 mm | ANSI 40 | 7.92 mm ❌ |
| 10B | 15.875 | 10,16 mm | ANSI 50 | 10.16 mm ✓ |
| 12B | 19.05 | 12.07 mm | ANSI 60 | 11.91 mm ≈ |
| 16B | 25.4 | 15,88 mm | ANSI 80 | 15.88 mm ✓ |
❌ = Non-interchangeable; tooth profile geometry differs significantly. ✓ = Roller diameter coincidentally matches; inner width still differs — verify before assuming interchangeability.

What European OEMs and Procurement Teams Require — and What We Deliver
Componentes complementares de acordo com a norma DIN
Building a complete DIN-standard roda dentada de aço inoxidável drive requires European-standard chain — not ANSI chain — and matching hardware:
- Corrente de rolos em aço inoxidável DIN 8187 / ISO 606 — 304 and 316 grades, 06B through 20B
- European-Standard SS Connecting Links — tipos de encaixe por pressão e de mola
- Rodas dentadas intermediárias DIN 8187 SS — for tensioning on European-pitch drives
- Conjuntos de buchas cônicas métricas — metric bore versions for European shafts
- DIN 6885 Shaft Keys — A2-70 stainless, all metric key sizes

Feedback do cliente
“We source 12B SS sprockets for our Netherlands dairy line. DIN compliance confirmed, EN 10204 3.1 certs included. Ever-Power is now our preferred supplier over Renold for stainless variants — better price and faster delivery.”
“08B 316 SS with electropolish for a GMP tablet coating line — delivered correctly specified, passed incoming QC without remedial work. Clean metric bore, correct key. Will order again.”
“10B SS sprockets for a Swedish water treatment clarifier — 316 grade, 12-month service, no corrosion. Non-stock tooth count added some lead time but quality was excellent.”
