Product Overview

What Is ISO 1275 Long Pitch Roller Chain?

ローラーチェーン

ISO 1275 defines large-pitch power transmission roller chains with pitches from 38.1 mm (M56) through 101.6 mm (M224) — the range above the short-pitch ISO 606 family. These are the chains of choice when a drive demands large sprocket diameter clearance, very low rotational speeds with high torque, or dimensional compatibility with legacy heavy industrial equipment.

Ever Power supplies ISO 1275 long-pitch roller chains manufactured to ISO 1275:2006 dimensional and minimum tensile strength requirements. Standard pitch sizes M56, M80, M112, M160, and M224 are held in UK stock in carbon steel simplex configuration. Duplex strands, 316L stainless steel, and custom-specification modifications are available to order with a 4–6 week production lead time.

Every production batch is proof-load tested to 50% of published minimum tensile strength before despatch. Dimensional inspection certificates and EN 10204 3.1 material mill certificates are available on request (standard on all stainless steel orders).

Standards Comparison

ISO 1275 vs ISO 606 — When to Specify Each

Both standards govern roller chain geometry and tensile strength but cover different pitch ranges designed for different operating regimes.

✦ ISO 1275 — Long Pitch (This Product)

✓ Pitch 38.1 mm to 101.6 mm

✓ Low speed, very high torque drives

✓ Large sprocket diameter required by design

✓ Legacy heavy equipment dimensional match

✓ Mining, quarrying, timber, press-room

✓ German / European DIN 8153 equivalent

✓ Simplex and duplex configurations

✓ Up to 560 kN minimum tensile (M224)

ISO 606 — Short Pitch (Standard Roller Chain)

✓ Pitch 9.525 mm to 76.2 mm (06B–48B)

✓ General purpose power transmission

✓ Higher rotational speeds

✓ Agriculture, automotive, packaging

✓ Widest UK stock availability

✗ Not interchangeable with ISO 1275 sprockets

✗ Different roller Ø at shared 38.1 mm pitch

→ See Simple Roller Chains

⚠ Important: At 38.1 mm pitch, ISO 1275 M56 and ANSI B29.1 120-1 share the same nominal pitch but have different roller diameters, inner widths, and tensile ratings — they are not interchangeable on the same sprocket.

Technical Data

ISO 1275 Roller Chain Specifications

Data per ISO 1275:2006. Minimum tensile values apply to simplex. Duplex ≈ 1.8× simplex. Weight figures are for carbon steel; 316L stainless adds approximately 2–3%.

M112 Long Pitch Chain · Yorkshire Aggregate Plant

“We had been running standard ANSI 120-1 on the primary crusher feed conveyor, replacing every 14 months due to fatigue cracking. Switching to M112 ISO 1275 with the HSP grade recovered the design pitch clearance at the sprocket and extended our replacement interval to 22 months.”

よくある質問

ISO 1275 Chain — Technical & Commercial FAQ

What is the difference between ISO 1275 and ISO 606?

ISO 606 defines short-pitch precision roller chains (06B–48B, pitches 9.525 mm to 76.2 mm), designed for general-purpose power transmission at moderate to high rotational speeds.

ISO 1275 defines long-pitch roller chains (M56–M224, pitches 38.1 mm to 101.6 mm). Although both standards include a 38.1 mm pitch size, the roller diameter, inner width, and tensile strength differ — they are not interchangeable on the same sprocket.

DE Was ist der Unterschied zwischen ISO 1275 und DIN 8153?

DIN 8153 ist die deutsche Norm für langgliedrige Rollenketten und inhaltlich äquivalent zu ISO 1275:2006. Die Kettennummern und alle Nennmaße sind identisch.

Wir liefern nach Deutschland, Österreich und in die Schweiz: [email protected]

How do I identify my existing long-pitch chain size?

1. Pitch (P): Pin-centre to pin-centre across a single link. ISO 1275 nominal values: 38.10 / 50.80 / 63.50 / 76.20 / 101.60 mm.

2. Roller diameter (d): Outer diameter of a free-rotating roller. This distinguishes ISO 1275 from ANSI at shared pitches.

Send us your measurements and we will confirm the designation within one working day.

Do you stock M56 and M80 for immediate UK delivery?

Yes. M56 and M80 in carbon steel simplex are held in UK stock in Bury St Edmunds. Orders placed before 12:00 noon are despatched same day. M56 and M80 in 316L stainless steel are also stocked. M112, M160, and M224 are produced to order.

DE Liefern Sie langgliedrige Rollenketten nach Deutschland?

Ja. Wir liefern ISO 1275 / DIN 8153 Rollenketten nach Deutschland, Österreich und in die Schweiz. Standardgrößen M56 und M80 innerhalb von 3–5 Werktagen nach DE. [email protected]

What documentation is provided with an order?

Standard: Dimensional inspection report · Proof-load test certificate (50% of min. tensile).

On request: EN 10204 3.1 mill certificate · NSF H1 lubricant data sheet · BRCGS / HACCP compliance documents.

Can you supply duplex or custom-attachment ISO 1275 chain?

Yes. Duplex approximately doubles the minimum tensile strength. Triplex available on M56 and M80. Attachment options: K1, K2, A1, A2 plates, extended pins, hollow-pin. Surface treatments: zinc-nickel, black oxide, PTFE dry-film. 50 m MOQ, 4–6 weeks from drawing approval. [email protected]
