Dayton

Dayton 6L017 Rigid Steel Coupling 1.5 in OD 500 RPM 575 in-lb

SKU CH-4QJC-FWHP8 MPN 6L017

Rigid carbon-steel shaft coupling joins 1 3/4 in and 2 3/4 in keyed bores at up to 500 RPM and 575 in-lb torque

  • Product typeDrain Components
  • Rigid one-piece carbon steel construction resists flex under load
  • Zinc-plated finish protects against corrosion in damp environments
  • 500 RPM maximum speed suits moderate-duty power transmission
  • 575 in-lb torque rating handles substantial twisting forces
  • 5 in outside diameter fits standard shafting arrangements

Rigid Steel Coupling for 1.5 in Shafts

The Dayton 6L017 is a one-piece carbon steel coupling designed to join two 1.5 inch outside diameter shafts. Its round keyed bores measure 1 3/4 inch and 3/4 inch respectively, each with matching keyway dimensions for positive torque transmission. Zinc plated finish adds corrosion resistance for industrial and automotive driveline applications.

One-Piece Construction and Keyed Mounting

The solid carbon steel body eliminates backlash and maintains alignment under load without separate hubs or fasteners. Keyway widths of 1 3/16 inch and 3/16 inch with corresponding depths of 1 3/32 inch and 3/32 inch accept standard keys for secure engagement. The 2 inch overall length keeps the assembly compact inside housings or machinery frames.

Rated for 575 in-lb at 500 RPM

Maximum torque capacity is 575 in-lb while the speed limit is 500 RPM, making this coupling suitable for low-speed, high-torque drives such as conveyors, pumps or heavy equipment accessories. Buyers needing higher rotational speeds or greater torque capacity should select a different coupling model.

Questions about this item

What speed does the 500 RPM rating cap for this coupling?

The 500 RPM rating sets the maximum rotational speed the zinc-plated carbon steel coupling can safely transmit without exceeding its design limits.

What shaft diameters and keyway sizes must match for the 1.5 in OD coupling to fit?

Both bores are 1 3/4 in and 2 3/4 in round keyed; keyways are 1 3/16 in wide by 1 3/32 in deep and 2 3/16 in wide by 2 3/32 in deep respectively.

How is the one-piece rigid coupling installed and what step is often missed?

Slide the coupling onto both aligned shafts, engage both keyways with their keys, then secure with set screws or retaining rings; the step often missed is verifying both keys are fully seated before tightening.
