Stock Bore Platewheel K80A

Stock Bore Platewheel K80A

The K80A platewheel (25.400 mm pitch) is a flat-disc, hub-less sprocket designed for welding or bolting directly to shafts, discs, or flanges — ideal where conventional hub sprockets cannot be accommodated due to space constraints. Manufactured from C45 steel with induction-hardened teeth (HRC 50–60), it covers Z=10–90 and is widely used in conveyors, automated sorting systems, and retrofitted drives across Australia.

Key Features

Flat Disc (No Hub) Design
Platewheel design eliminates the hub — enabling direct welding or bolting to shafts, flanges, or driven discs where standard hub sprockets would interfere with adjacent components.
⚡
Simple Mounting Flexibility
Bolt pattern or weld attachment allows the platewheel to be secured at any angular position and repositioned if the drive geometry changes — no keying or boring required.
Hardened Teeth
Induction-hardened tooth flanks (HRC 50–60) provide full wear resistance despite the thinner cross-section compared to hub-type sprockets.
Wide Tooth Range
Z=10–90 tooth counts available — enabling drive ratios from 1:1 to extreme reductions in a single platewheel product family.

Compatibility

Designed for 25.400 mm pitch roller chain (Asian standard K-series equivalent). The platewheel is supplied without a bore — it is intended for welding or bolting to your shaft or flange. Bolt-circle drilling available on request. Contact our team for custom drilling or welding preparation options.

Customer Reviews

Grant S.  ★★★★★ Australia
“Welded K80A platewheels to our roller-conveyor drive shafts — perfect fit, clean weld preparation, and teeth aligned perfectly with our existing chain.”
K80A Z=19 Platewheel · March 2025
Mei L.  ★★★★★ China
“Excellent flatness on the disc face — our welding team confirmed less than 0.2 mm run-out after welding. Good manufacturing quality.”
K80A Z=25 Platewheel · January 2025
Ben A.  ★★★★☆ New Zealand
“Good product, slightly longer lead time than expected for custom tooth count but quality was worth it.”
K80A Z=30 Platewheel · February 2025
Frank B.  ★★★★★ Germany
“We use these as OEM components on our conveyor modules. Consistent quality across batches of 500+ pieces.”

FAQ

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