\n\n►  What chain does the NK series sprocket use?<\/summary>\n
The NK60-2B sprocket is designed for 19.050 mm pitch roller chain of Asian-standard origin (matching ANSI-derived dimensions). Always verify inner width and roller diameter when selecting chain.<\/div>\n<\/details>\n
\n\n►  What is the difference between B Type Solid and B Type Weld?<\/summary>\n
B Type Solid has a machined hub bore (standard or finished to drawing). B Type Weld has a welded-on hub plate for applications where the sprocket must be welded to a shaft stub or disc.<\/div>\n<\/details>\n

Yes. Specify your shaft diameter and keyway dimensions at order. Finished bore lead time is 5\u20137 days from order confirmation.<\/div>\n<\/details>\n
\n\n►  Can I get a material test certificate for the C45 steel?<\/summary>\n
Yes. EN 10204 2.2 chemical composition certificates are available on request. Contact us before ordering to arrange documentation.<\/div>\n<\/details>\n
\n\n►  What is the maximum bore for each tooth count?<\/summary>\n
Maximum bore increases with tooth count. Contact our sales team with your tooth count and required bore diameter \u2014 we will confirm feasibility and maximum available bore.<\/div>\n<\/details>\n
    \n
  1. Verify bore size against shaft diameter; machine finished bore if required.<\/li>\n
  2. Clean shaft and bore; apply light machine oil to ease assembly.<\/li>\n
  3. Position sprocket and align within 0.5 mm lateral offset of the mating sprocket.<\/li>\n
  4. Install roller chain and set slack-side tension to 2% of centre distance.<\/li>\n
  5. Check all set-screws and key fit after initial 4-hour loaded operation.<\/li>\n<\/ol>\n
