\n\n►  Is the ISO 04B-1 sprocket the same as the ANSI #25 sprocket?<\/summary>\n
No. ISO 04B-1 has a 6.000 mm pitch, while ANSI #25 has a 6.350 mm pitch (1\/4 inch). They are not interchangeable \u2014 always verify the chain pitch before ordering.<\/div>\n<\/details>\n
\n\n►  Can I use a 04B-2 (duplex) sprocket with a simplex chain?<\/summary>\n
No. Duplex chain must be used with duplex sprockets. Mixing strand counts will cause the chain to ride incorrectly on the sprocket teeth and will result in rapid wear or chain jumping.<\/div>\n<\/details>\n
\n\n►  What is the maximum shaft diameter for a 04B-1 Z=10 sprocket?<\/summary>\n
A standard Z=10 stock bore is typically 12\u201318 mm depending on the hub style. Custom finished bores are available to your specified diameter with 5\u20137 day lead time.<\/div>\n<\/details>\n
\n\n►  Do you supply platewheels (flat plate type) for 04B?<\/summary>\n
Yes. ISO 04B-1 platewheels (without hub, suitable for welding to shafts or discs) are available in our range. Contact our sales team for dimensions and pricing.<\/div>\n<\/details>\n
\n\n►  What lubrication is recommended for 04B drives?<\/summary>\n
For speeds below 100 rpm, manual brush lubrication with ISO VG 68\u2013100 oil. Above 100 rpm, drip lubrication or bath lubrication is preferred. For sealed or food applications, use NSF H1 approved grease.<\/div>\n<\/details>\n

Installation & Maintenance<\/h2>\n
    \n
  1. Confirm shaft and bore dimensions; clean contact surfaces with solvent.<\/li>\n
  2. Align mating sprockets within 0.5\u00b0 angular misalignment and 1 mm lateral offset.<\/li>\n
  3. Set chain tension with 2% sag on the slack side relative to centre distance.<\/li>\n
  4. Torque set-screws to the manufacturer specification stamped on the hub.<\/li>\n
  5. Check alignment and tension after 4 hours of initial operation.<\/li>\n<\/ol>\n
