  • 13-tooth design matches ANSI B 29.1 chain pitch precisely
  • Quick-detachable SK bushing enables fast tool-free changes
  • Black-oxide finish protects steel from corrosion
  • 82 in outside diameter fits standard 100-series drives

Precision Power Transmission Component

The Tritan 100SK13H is a hardened steel roller chain sprocket engineered for ANSI 100 single-strand chain with a 1 1/4 inch pitch. Its thirteen teeth and 5.223 inch pitch diameter deliver precise engagement for industrial drive systems requiring reliable torque transfer.

Thermal And Mechanical Stability

Hardened teeth resist wear under continuous load while the black oxide finish adds corrosion protection during normal operation. The steel body dissipates heat generated by chain friction without active cooling, maintaining dimensional stability across the 5.82 inch outside diameter.

Quick Detachable Bushing Compatibility

Designed for SK quick-detachable bushings, the sprocket accepts a maximum bore of 2 5/8 inch through a 2 1/8 inch length with a 3 15/16 inch hub diameter. The 0.558 inch hub projection and 0.692 inch tooth width align with ANSI B 29.1 and BIS standards for secure mounting without additional machining.

Questions about this item

How do I install the SK bushing onto the 13-tooth sprocket without damaging the 0.558 in hub projection?

Slide the Quick Detachable SK bushing into the 2 5/8 in maximum bore, align the keyway, then torque the cap screws evenly to the bushing manufacturer's specification; over-tightening can distort the 0.558 in hub projection and cause run-out.

Which wear surfaces on this hardened-tooth sprocket should I inspect during scheduled maintenance?

Monitor the 0.692 in tooth width for hooking or elongation, check the 5.223 in pitch diameter for chain stretch beyond ANSI B 29.1 limits, and verify the black-oxide finish has not worn through to bare steel.

At what point does the 13-tooth, 5.82 in outside diameter sprocket become the limiting factor in a high-speed drive?

The 13-tooth geometry reaches chordal-action vibration limits first; at high RPM the polygon effect on the 5.223 in pitch diameter creates speed variation that exceeds what the hardened teeth or SK bushing can compensate for.
