Steel SK quick-detachable bushing, 2 in bore, 1.875 in long, split flange

Tb Wood'S

Tb Wood'S SK2 Quick Detachable Bushing 2 in bore 1.875 in length Steel

SKU CH-FH1C-B9QWQ

A quick-detachable steel bushing with a 2 in bore, 1.875 in length and 3.31 in bolt circle for keyed shafts

  • Quick detach design speeds up maintenance
  • 2 inch bore fits standard shafts directly
  • 875 inch length provides secure grip
  • Grade 5 steel handles high torque loads
  • Split flange with three cap screws included

SK-Series Quick-Detachable Bushing

The SK2 bushing fits a 2 in keyed shaft and uses a split-flange taper to clamp without set screws. Three included cap screws draw the halves together for a concentric grip on pulleys or sprockets.

Taper and bolt-circle limits

A 3/4 in per ft taper and 3.31 in bolt circle fix the hub geometry that can accept this bushing. Hubs with a different taper angle or bolt pattern will not align with the three 5/16-18 mounting holes.

2 in bore decides fit

The 2 in bore diameter is the single dimension that must match the shaft exactly; an undersized or oversized shaft will prevent full engagement of the 1/2 in by 1/4 in keyway.

Questions about this item

How do I choose the correct SK-series bushing for my shaft?

Match the 2 in bore diameter and 1/2 in keyway width to your shaft dimensions; the SK series uses a 3/4 in per ft taper and 3.31 in bolt circle.

What does the 1.875 in overall length mean when the bushing is mounted?

The total length including the 1/2 in flange is 1.875 in; the tapered grip portion measures 1.375 in less flange.

What does the 5/16 in‑18 bolt specification limit in practice?

Three SAE Grade 5 cap screws on a 3.31 in bolt circle clamp the split flange; torque them to the grade‑5 value for that thread size.
