Climax Metal Products Rigid Shaft Coupling 1 in Bore Stainless Steel 4000 RPM 1330 in-lb

SKU CH-BQP6-F6G0Y

One-piece stainless-steel rigid coupling joins two 1-inch round keyed shafts, rated for 4000 RPM and 1330 in-lb torque

  • Stainless steel resists corrosion in wet environments
  • One-piece rigid design maintains precise shaft alignment
  • Clamp-on locking secures shafts without set-screw damage
  • 4000 RPM rating supports high-speed power transmission
  • 1330 in-lb torque capacity handles heavy loads

Rigid Coupling for 1 in Shafts

This one-piece stainless steel coupling joins two 1 in round keyed shafts with a clamp-on lock. It suits machinery that requires a solid, backlash-free connection between aligned shafts in industrial or automotive drivelines.

Stainless Steel Holds at 4000 RPM

The stainless steel body resists corrosion while transmitting up to 1330 in-lb of torque at speeds up to 4000 RPM. Its one-piece construction maintains alignment under sustained load without the compliance or wear of flexible alternatives.

Replaces Two-Piece or Flexible Couplings

Use this when a rigid, zero-backlash joint is needed and shaft alignment can be held precisely. It is not for systems that require misalignment compensation, vibration damping, or axial movement between shafts.

Questions about this item

How much heat or noise does the 4000 RPM rigid coupling generate during continuous operation?

The one-piece stainless steel coupling has no moving contact surfaces, so it adds negligible heat and runs silently at speeds up to 4000 RPM.

What shaft and keyway must already be on the motor and driven equipment for this coupling to clamp on?

Both shafts need a 1-inch round bore with a 1/4-inch wide keyway cut to 1/8-inch depth to match the clamp-on hub.

Will the 2.06-inch clearance diameter fit inside the existing guard or housing on my legacy pump?

The coupling’s 2.06-inch clearance diameter requires at least that much radial space inside any guard or bell housing you keep.
