Renold Roller Chain Range — Quick Reference
Renold is the world-leading roller chain manufacturer (since 1879) — used in demanding industrial drives and conveyors globally. Known for consistent dimensional accuracy and long service life. AIMS stocks Renold standard roller chain in industry-standard sizes. Selection turns on PITCH (ASA / BS / ISO standard) and CONFIGURATION (simplex/duplex/triplex).
| Renold Series | Pitch | Configuration | Best For |
|---|---|---|---|
| A&S AR40A (No.40) | 1/2" (12.7 mm) | Simplex single-row | Light industrial drives, small motors, light conveyor |
| A&S AR50A (No.50) | 5/8" (15.875 mm) | Simplex single-row | Medium industrial drives — workshop default |
| A&S AR60A (No.60) | 3/4" (19.05 mm) | Simplex single-row | Heavier industrial, agricultural, conveyors |
| A&S AR80A (No.80) | 1" (25.4 mm) | Simplex single-row | Heavy industrial machinery, mining plant |
| A&S AR100A (No.100) | 1-1/4" (31.75 mm) | Simplex single-row | Very heavy industrial, large machinery |
| Duplex (2-Row) | Per pitch — same as simplex | 2 strands side-by-side | Double power capacity at same speed as simplex |
| Triplex (3-Row) | Per pitch — same as simplex | 3 strands side-by-side | Triple power capacity — heavy industrial |
| Connecting + Offset Links | Per pitch | — | Joining chain ends, single-link length adjustment |
ASA (American Standard) is the dominant standard in Australian + US industry. BS / ISO standards are common in European-origin equipment. Sizing: pitch defines chain power capacity; chain length matched to drive geometry. Supplied in 10-foot lengths typically. Companion ranges: roller chain, sprockets, chain couplings, chain tensioners. For complete background, see our roller chain guide.
Renold Roller Chain at AIMS Industrial
Renold is a world-leading manufacturer of roller chain and power transmission products, with a history stretching back to 1879. Renold chain is trusted in demanding industrial applications globally — known for consistent quality, dimensional accuracy and long service life. AIMS Industrial stocks Renold standard roller chain for industrial drive and conveyor applications.
Renold Roller Chain at AIMS
AIMS stocks Renold chain in two industry-standard formats:
The Renold A&S AR50A1 All-Purpose Standard Chain is a No.50 pitch American Standard (ASA) simplex chain supplied in 10-foot lengths. Renold's A&S (As-and-Sprocket) designation indicates a standard-duty chain suited to general industrial conveyor and drive applications at moderate speeds and loads.
The Renold 10B-3 Standard Roller Chain is a 10B pitch British Standard (BS) triplex chain in 10-foot lengths. Triplex configuration provides high load capacity in a compact format — commonly used in heavy industrial drives, agricultural machinery and equipment where high power density is needed.
Why Renold Chain
Renold's precision manufacturing ensures consistent pin, bushing and plate dimensions that reduce wear and extend drive life. For critical drives where chain quality directly affects maintenance schedules and production uptime, Renold is a proven choice.

People Also Ask — Renold
Q: What is the difference between the Renold A&S AR50A1 and the Renold 10B-3 chain?
The Renold A&S AR50A1 is a No.50 pitch American Standard (ASA) simplex (single-row) chain, suited to general industrial conveyor and drive applications at moderate speeds and loads. The Renold 10B-3 is a 10B pitch British Standard (BS) triplex (3-row) chain, giving high load capacity in a compact format for heavy industrial drives, agricultural machinery and equipment needing high power density. Both are supplied in 10-foot lengths.
Q: Why does the ASA standard matter for Renold chain selection?
ASA (American Standard) is the dominant chain standard in Australian and US industry, while BS and ISO standards are common in European-origin equipment. AIMS stocks Renold chain in both an ASA-format (A&S AR50A1) and a BS-format (10B-3) so you can match the replacement chain to whichever standard your existing drive or sprockets were built to.
Q: Are the two Renold chain formats AIMS stocks supplied in the same length?
Yes — both the Renold A&S AR50A1 (No.50 pitch ASA simplex) and the Renold 10B-3 (10B pitch BS triplex) are supplied in 10-foot lengths, despite differing in pitch standard, configuration and load capacity.
