  • 1 in round bores on both ends simplify shaft matching
  • Rated for 4,000 RPM continuous operation
  • 2,600 in-lb torque capacity handles heavy loads

Rigid Shaft Coupling 1.85 in OD

The Dayton 3ZN36 is a one-piece rigid shaft coupling made from carbon steel. It connects two 1 inch round bores with a 1.85 inch outside diameter. The coupling is rated for 4000 RPM and 2600 in-lb maximum torque.

For direct in-line shaft connections

This coupling suits applications that join two shafts of identical 1 inch diameter in a fixed alignment. It is not for installations that require angular misalignment compensation, vibration damping, or connections between different bore sizes.

2600 in-lb torque rating

The maximum torque capacity of 2600 in-lb determines whether this coupling can handle the load. Verify the application's peak torque against this figure before selecting the part.

Questions about this item

How often should the carbon-steel coupling be inspected for wear?

Inspect the coupling periodically for corrosion or bore deformation; carbon steel has no self-lubricating feature so schedule checks based on your shaft alignment and load cycles.

What torque ceiling stops continuous operation first?

The 2,600 in-lb maximum torque rating is the hard limit; sustained loads above this value will cause permanent deformation of the one-piece carbon-steel body.

How hot does the coupling get at 4,000 RPM?

At 4,000 RPM the carbon-steel coupling runs warm from friction but has no internal heat source; surface temperature stays near ambient unless misalignment adds extra load.
