Stainless steel one-piece rigid shaft coupling, 7/8 inch diameter, 1 3/8 inch length

Ruland Manufacturing

Ruland Manufacturing CLX-6-6-SS Rigid Shaft Coupling 3/8 in Bore Stainless Steel

SKU CH-22K1-JM9MB

One-piece stainless-steel rigid coupling joins two 3/8 in shafts, rated to 4,000 RPM and 145 in-lb torque

  • Rigid one-piece design ensures precise shaft alignment
  • Stainless steel construction resists corrosion in harsh environments
  • 145 in-lb torque rating handles demanding power transmission
  • 4,000 RPM maximum speed supports high-speed applications
  • 03 in clearance diameter fits compact machinery spaces

Rigid Shaft Coupling 3/8 in Bore

The Ruland Manufacturing CLX-6-6-SS is a one-piece rigid shaft coupling machined from stainless steel. It connects two shafts with identical 3/8 in round bores for precise alignment in power transmission assemblies. The component suits maintenance teams and machine builders who need a permanent, backlash-free joint.

Maximum Speed 4,000 RPM Limit

The coupling is rated for a maximum rotational speed of 4,000 RPM. Operation beyond this limit risks mechanical failure and reduced service life. The one-piece construction offers no flexibility to accommodate misalignment, so shafts must be accurately aligned during installation to avoid vibration and bearing wear.

Maximum Torque 145 in-lb Capacity

The stainless steel body transmits up to 145 in-lb of torque, providing headroom for light to moderate duty drives. Applications demanding higher torque will exceed the coupling's rating and require a larger or alternative design. The 7/8 in outside diameter and 1 3/8 in overall length define the spatial envelope for mounting.

Questions about this item

Should I choose the one-piece stainless steel coupling or look for a two-piece version?

The CLX-6-6-SS is a one-piece rigid coupling with 3/8 in bores on both ends and a 7/8 in outside diameter, so it installs as a single unit without split halves.

What does the 145 in-lb torque rating mean once the coupling is installed on my shafts?

It is the maximum torque the stainless steel body can transmit continuously at up to 4,000 RPM without yielding, provided both shafts are precisely aligned and the bores fit the 3/8 in diameter.

How does the rigid one-piece design limit misalignment compared to a flexible coupling?

Because the coupling has no flexible element, it transmits torque only when both shafts share the same centreline; any angular or parallel offset will load the shafts and bearings instead of being absorbed.
