  • 281 in-lb torque rating handles demanding loads
  • 3,500 RPM limit suits high-speed applications

Aluminium rigid coupling for 5/8 inch shafts

This one-piece aluminium coupling joins two 5/8 inch shafts with a set-screw lock. It suits light-duty power transmission where precise alignment can be maintained and no keyway is required.

Torque limited to 281 in-lb and 3 500 RPM

The plain bore and single set screw transmit torque only through friction, so the rated 281 in-lb and 3 500 RPM ceiling must not be exceeded. Shock loads or misalignment will reduce the practical limit further.

Plain-finish aluminium with 1.25 inch clearance

The 1.25 inch outside diameter and 1.25 inch clearance diameter leave a compact profile for tight assemblies. Plain finish offers no corrosion protection, so the coupling is best kept in dry, indoor environments.

Questions about this item

Should I pick the 5/8 in bore or the 1 1/4 in outside diameter version?

This coupling has a fixed 5/8 in bore and a 1 1/4 in outside diameter; both dimensions belong to the same single part.

What does the 281 in-lb torque rating mean when the coupling is installed?

It is the maximum torque the coupling can transmit continuously without slipping or damaging the set screw connection.

How does the 5/16-18 set screw interface limit the coupling's performance?

The single 5/16-18 set screw secures the shaft and the 281 in-lb torque capacity assumes proper tightening on a 5/8 in shaft.
