Key Features<\/h2>\n
\n
\n
<\/div>\n
\n
Roller Chain Flexible Coupling<\/div>\n
Two coupling sprockets and a length of double-strand (duplex) roller chain form a compact flexible coupling that tolerates angular misalignment up to 1\u00b0 and parallel offset up to 0.5 mm.<\/div>\n<\/div>\n<\/div>\n
\n
<\/div>\n
\n
Shock-Load Absorption<\/div>\n
The roller chain element absorbs shock and vibration between motor and load \u2014 protecting gearboxes, pumps, and driven machines from torque spikes common in start-stop operations.<\/div>\n<\/div>\n<\/div>\n
\n
\u2699\ufe0f<\/div>\n
\n
Easy Maintenance<\/div>\n
Chain coupling disassembly requires only disconnecting the roller chain link \u2014 no alignment tools or heat required. Chain replacement restores full coupling performance without disturbing shaft alignment.<\/div>\n<\/div>\n<\/div>\n
\n
<\/div>\n
\n
High Torque Capacity<\/div>\n
Double-strand roller chain wraps two tooth profiles simultaneously, providing significantly higher torque capacity per unit diameter than jaw or disc couplings of equivalent size.<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Compatibility<\/h2>\n

The NK60-2B coupling sprocket is used as a matched pair with a duplex (double-strand) roller chain forming a complete roller-chain coupling. Both sprockets must be the same model and tooth count. Bore finished to your shaft diameter; keyway and set-screw included on solid-hub types. Contact our team<\/a> for torque and misalignment calculations.<\/p>\n

FAQ<\/h2>\n
\n\n►  How many teeth do I need for a coupling sprocket pair?<\/summary>\n
Both coupling sprockets must have the same tooth count. The most common tooth counts are 9, 10, 11, and 12. More teeth = smoother operation but larger coupling diameter.<\/div>\n<\/details>\n
\n\n►  What chain do I use with coupling sprockets?<\/summary>\n
Roller chain coupling assemblies use a length of double-strand (duplex) roller chain in the appropriate pitch. The chain pitch must match the sprocket pitch exactly.<\/div>\n<\/details>\n
\n\n►  How much misalignment can a roller chain coupling tolerate?<\/summary>\n
Typically \u00b11\u00b0 angular misalignment and \u00b10.5 mm parallel offset at the rated torque. Misalignment beyond these limits increases chain and sprocket wear significantly.<\/div>\n<\/details>\n
\n\n►  Do you supply the complete coupling set (sprocket pair + chain)?<\/summary>\n
Yes. We can supply matched pairs of coupling sprockets with the appropriate length of duplex chain and chain housing (cover) as a complete coupling kit. Contact us for full kit pricing.<\/div>\n<\/details>\n
\n\n►  What is the maximum torque for the NK80B coupling sprocket?<\/summary>\n
Torque capacity depends on tooth count and chain pitch. For NK80B Z=10, typical rated torque is 350\u2013500 Nm depending on speed. Contact our engineering team for a precise calculation for your application.<\/div>\n<\/details>\n
    \n
  1. Finish-bore both coupling sprockets to the respective shaft diameters; cut keyways to drawing.<\/li>\n
  2. Mount sprockets on their respective shafts; align shafts using a dial indicator \u2014 target less than 0.1 mm TIR on coupling hub face.<\/li>\n
  3. Wrap the duplex roller chain around both sprockets and close with a connecting link.<\/li>\n
  4. Install the chain coupling housing (cover) if required for guard compliance or lubrication retention.<\/li>\n
  5. Verify shaft alignment monthly during the first 3 months of operation and re-check after any unexpected load or vibration event.<\/li>\n<\/ol>\n
