Black oxide steel rigid shaft coupling with keyway

Climax Metal Products

Climax Metal Products RC-200-KW Conduit, 2in Bore, 3-5/16in OD, 4-1/2in L, Keyway

SKU CH-RPW7-A75TP

Rigid steel shaft coupling joins two 2-inch shafts using a 1/2-inch keyway and set-screw fastening

  • Rigid steel coupling transmits high torque
  • 2 in bore fits standard shafts
  • Keyway prevents rotational slippage
  • Black oxide finish resists corrosion
  • 4-1/2 in length suits compact assemblies

Rigid Shaft Coupling for 2-Inch Bore

This Climax Metal Products RC-200-KW is a rigid shaft coupling designed to connect two shafts with a 2-inch bore diameter. It is built from steel with a black oxide finish and includes a keyway for positive torque transmission. The coupling suits maintenance teams and OEMs needing a solid, zero-backlash connection in power transmission assemblies.

Installation Uses Set Screws and Keyway

Installation requires aligning the coupling over both shaft ends and tightening the 1/2-13 set screws against the keyway and shaft flats. The 3.313-inch clearance diameter provides room for tool access during fastening. Misalignment between shafts will cause vibration and premature bearing wear because this coupling has no flexible element to compensate.

Suits Fixed Inline Shafts Only

This unit fits applications where shafts stay permanently aligned and a 4-1/2-inch overall length is acceptable. It is not for buyers who need angular or parallel misalignment compensation, axial float, or a shorter coupling envelope. Builders requiring a flexible or tapered-grid design should look at a different coupling style.

Questions about this item

How can I confirm the RC-200-KW coupling is correctly installed and transmitting torque?

After tightening the 1/2-13 set screw against the shaft key, rotate the assembly by hand to verify zero backlash and that the keyway engages fully without binding.

What components are included with the RC-200-KW and what must I supply?

The box contains the single-piece steel coupling with black oxide finish and the 1/2-13 set screw; you must provide the matching 1/2 in key and both shafts.

When should I choose the RC-200-KW keyway version instead of a plain bore coupling?

Select this model when your 2 in shafts have a 1/2 in keyway and you need positive drive with a 3.313 in clearance diameter.
