<\/span>Key Product Features<\/h2>\n
\n
\n\n <\/span> Most Popular ISO Sprocket Size<\/summary>\n
12.7 mm pitch (1\/2 inch) is the global standard for medium-duty chain drives, with the largest selection of chain types and complementary components readily available.<\/div>\n<\/details>\n
\n\n <\/span> Induction-Hardened Teeth<\/summary>\n
HRC 50\u201360 surface hardness with \u22640.05 mm thermal deformation ensures 3\u00d7 the wear life of untreated sprockets at comparable cost.<\/div>\n<\/details>\n
\n\n <\/span> Complete Format Range<\/summary>\n
Available as finished bore, pilot bore, taper-sleeve (TS, TD, TT bush types), split taper bushing, and welded hub \u2014 every installation scenario covered.<\/div>\n<\/details>\n
\n\n <\/span> Simplex, Duplex & Triplex<\/summary>\n
Single, double, and triple-strand options allow graduated torque capacity from light-duty (08B-1) to heavy industrial (08B-3) without changing sprocket diameter or chain pitch.<\/div>\n<\/details>\n<\/div>\n

Compatibility & Chain Selection<\/h2>\n

The ISO 08B-1 sprocket is designed for DIN 8187 \/ ISO 606 08B-1 roller chain<\/strong>: pitch 12.7 mm, inner width 7.75 mm, roller \u03a6 8.51 mm. 08B-1 Finished Bore<\/strong> versions are pre-machined and ready to install on shafts from 16 mm to 75 mm (Z-dependent). Taper bush variants<\/strong> accept 1008\/1210\/1610\/2012\/2517 taper bushings. Cross-reference: visit our full ISO 08B sprocket catalogue<\/a>.<\/p>\n

FAQ<\/h2>\n
\n\n►  Is the ISO 08B-1 sprocket the same as the ANSI #40 sprocket?<\/summary>\n
They have the same 12.7 mm pitch, but the chain dimensions differ: ISO 08B has inner width 7.75 mm while ANSI #40 has 7.92 mm inner width. The sprockets are NOT interchangeable \u2014 always confirm the chain standard before ordering.<\/div>\n<\/details>\n
\n\n►  What is the maximum bore for an 08B-1 Z=25 sprocket?<\/summary>\n
Typically 45\u201355 mm depending on hub style. Finished bore versions are custom-machined to your specification. Contact our team for maximum available bore for each tooth count.<\/div>\n<\/details>\n
\n\n►  Do you offer duplex and triplex versions in all tooth counts?<\/summary>\n
Duplex (08B-2) is available Z=8\u2013125. Triplex (08B-3) covers Z=8\u201376. Non-standard tooth counts outside the stock range require 7\u201314 days manufacturing.<\/div>\n<\/details>\n
\n\n►  Can stainless steel 08B-1 sprockets be supplied?<\/summary>\n
Yes. SS304 stainless 08B sprockets are available for food processing and marine applications. Lead time is typically 2\u20133 weeks.<\/div>\n<\/details>\n
\n\n►  What chain lubricant do you recommend for 08B-1 drives?<\/summary>\n
ISO VG 68\u2013100 mineral oil for general use; ISO VG 46 for high-speed drives; NSF H1 food-grade oil for food processing applications. Re-lubricate every 200 hours or as indicated by operating conditions.<\/div>\n<\/details>\n
    \n
  1. Degrease shaft and bore; verify bore matches shaft tolerance (H7\/k6 recommended).<\/li>\n
  2. Install sprocket; for taper-sleeve types, torque bushing bolts to the specified value on the bushing label.<\/li>\n
  3. Align driving and driven sprockets using a laser alignment tool or precision straight-edge \u2014 within 0.3 mm lateral offset.<\/li>\n
  4. Thread the 08B chain and use a chain link to close \u2014 do not over-tension.<\/li>\n
  5. Set slack-side sag to 2\u20133% of centre distance and re-check after the first 4 hours of load.<\/li>\n<\/ol>\n
