ANSI 40 roller chain is the most widely stocked short-pitch roller chain in North American and export industrial markets. Built to ASME B29.1 with a 1\/2 inch (12.70 mm) pitch, the 40 series covers simplex (40-1), duplex (40-2), and triplex (40-3) strand configurations, allowing load capacity to be doubled or tripled without changing the pitch or sprocket centre distance. Ever Power manufactures all three strand configurations from medium-carbon alloy steel, with case-hardened pins at 58\u201364 HRC, through-hardened bushings at 50\u201358 HRC, and shot-peened rollers for extended fatigue life. Standard finish is rust-preventive oil; stainless steel and nickel-plated variants are available on request.<\/p>\n

Per ASME B29.1-2011. ISO 08A-1 cross-reference: same pitch, roller diameter differs (8.51 mm vs 7.92 mm) \u2014 not interchangeable on the same sprocket.<\/p>\n

<\/p>\n

\n

ISO Cross-Reference:<\/span> ANSI 40-1 uses a 7.92 mm roller diameter. The nearest ISO equivalent (08A-1) has a 7.95 mm roller \u2014 functionally the same pitch but verify before fitting to existing sprockets. Not interchangeable with ISO 08B-1 (8.51 mm roller).<\/p>\n<\/div>\n

Material and Construction<\/h2>\n
\n
\n

Sidoplattor<\/p>\n

SAE 1040\u20131050 cold-stamped medium-carbon steel. Work-hardened surface resists fatigue crack initiation at pitch holes.<\/p>\n<\/div>\n

\n

N\u00e5lar<\/p>\n

Gas-carburised alloy steel. Surface hardness 58\u201364 HRC, core hardness 35\u201345 HRC for fatigue and impact resistance.<\/p>\n<\/div>\n

\n

Bussningar<\/p>\n

Through-hardened carbon steel, 50\u201358 HRC. Controlled interference press-fit prevents rotation under load without cracking.<\/p>\n<\/div>\n

\n

Rullar<\/p>\n

Shot-peened carbon steel, 58\u201364 HRC. Compressive residual stress extends fatigue life by 20\u201335% vs unpeened rollers.<\/p>\n<\/div>\n<\/div>\n
