  • Two-piece stainless-steel construction allows easy installation on aligned shafts
  • 1-inch round bore on both ends fits standard shafting without keyways
  • 1,200 in-lb torque capacity handles moderate power-transmission loads
  • Rated for 4,000 RPM maximum speed suits high-speed applications
  • 05-inch clearance diameter provides compact envelope in tight spaces

Rigid two-piece stainless coupling

The Ruland SPX-16-16-SS is a rigid shaft coupling machined from stainless steel for precise alignment between two 1 in round bores. It suits OEM machinery, test rigs and custom drives where zero backlash and corrosion resistance are required. The two-piece clamp design allows installation without removing mounted components.

Two-piece clamp frees assembly time

The split hub clamps around each shaft with four socket-head cap screws, so the coupling slides into position after gears, pulleys or bearings are already in place. No keyway is machined, leaving the full shaft diameter intact for maximum torque transmission. Clearance diameter is 2.05 in, overall length is 3 in, and the unit weighs 0 lb.

Replaces single-piece or keyed rigid couplings

The jump is worth it when shafts cannot be pulled for installation or when a keyway would weaken a 1 in shaft. It does not suit applications needing angular misalignment compensation, vibration damping or torque overload protection. Maximum rated speed is 4, 000 RPM and maximum torque is 1, 200 in-lb.

Questions about this item

How much torque can the coupling transmit before it becomes the limiting factor?

The two-piece stainless-steel coupling is rated for a maximum torque of 1,200 in-lb.

Will the coupling run hot or loud when operated continuously at 4,000 RPM?

At the rated 4,000 RPM the rigid stainless-steel construction generates minimal heat and no audible noise.

Do both shafts need to be exactly 1 in diameter with no keyways for this coupling to fit?

Yes, each bore is 1 in round with no keyway, so both shafts must match that size.
