Key Features<\/h2>\n
\n
\n
<\/div>\n
Flat Disc (No Hub) Design<\/div>\n
Platewheel design eliminates the hub \u2014 enabling direct welding or bolting to shafts, flanges, or driven discs where standard hub sprockets would interfere with adjacent components.<\/div>\n<\/div>\n
\n
\u26a1<\/div>\n
Simple Mounting Flexibility<\/div>\n
Bolt pattern or weld attachment allows the platewheel to be secured at any angular position and repositioned if the drive geometry changes \u2014 no keying or boring required.<\/div>\n<\/div>\n
\n
<\/div>\n
Hardened Teeth<\/div>\n
Induction-hardened tooth flanks (HRC 50\u201360) provide full wear resistance despite the thinner cross-section compared to hub-type sprockets.<\/div>\n<\/div>\n
\n
<\/div>\n
Wide Tooth Range<\/div>\n
Z=10\u201395 tooth counts available \u2014 enabling drive ratios from 1:1 to extreme reductions in a single platewheel product family.<\/div>\n<\/div>\n<\/div>\n

Compatibility<\/h2>\n

Designed for 12.700 mm pitch roller chain (Asian standard K-series equivalent). The platewheel is supplied without a bore \u2014 it is intended for welding or bolting to your shaft or flange. Bolt-circle drilling available on request. Contact our team<\/a> for custom drilling or welding preparation options.<\/p>\n

FAQ<\/h2>\n
\n\n►  Can the platewheel be drilled with a bolt pattern?<\/summary>\n
Yes. We can supply platewheels pre-drilled with your specified bolt circle diameter and hole size. Specify bolt pattern at order.<\/div>\n<\/details>\n
\n\n►  What filler material is recommended for welding K-series platewheels?<\/summary>\n
The C45 steel body accepts ER70S-6 or equivalent MIG filler. Preheat to 200\u00b0C for wall thicknesses above 12 mm to prevent heat-affected zone cracking. Do not weld directly on the tooth profile.<\/div>\n<\/details>\n
\n\n►  Is the tooth profile the same as a standard hub sprocket?<\/summary>\n
Yes. The tooth profile is identical to the equivalent K-series hub sprocket \u2014 the only difference is the removal of the hub, making the platewheel thinner overall.<\/div>\n<\/details>\n
\n\n►  What is the maximum operating speed for a platewheel?<\/summary>\n
Platewheel speed limits are determined by chain speed and tooth count. For Z=19 at a chain speed of 40 m\/min, RPM is approximately 300. Contact us for specific speed calculations.<\/div>\n<\/details>\n
\n\n►  Do you supply platewheels in stainless steel?<\/summary>\n
Yes. SS304 stainless platewheels are available for hygienic or corrosive environments. Contact us for available sizes and lead times.<\/div>\n<\/details>\n
    \n
  1. Position the platewheel on the shaft stub or mounting flange; check concentricity with a dial indicator (target TIR < 0.3 mm).<\/li>\n
  2. Tack-weld at 4 equidistant points before full weld run to maintain alignment.<\/li>\n
  3. Complete continuous weld fillet as per drawing specification; allow to cool slowly (do not quench).<\/li>\n
  4. Re-check tooth plane alignment after welding \u2014 correct if heat distortion has introduced misalignment.<\/li>\n
  5. Install roller chain and set tension; re-inspect weld integrity after first 50 hours of operation.<\/li>\n<\/ol>\n
