RC-062-KW4H@90 Black Oxide Plated Mild Steel Rigid Coupling, 5/8" Bore, 1-1/4" Outside Diameter, 2" Length, 5/16"-18 x 5/16" Set Screw

item is as described and works great.

I recently scored a brand new 1/3 horse continuous duty electric motor on the cheap and immediately had dreams of homemade lapidary equipment dancing in my head. The only issue was that the motor has a very short split arbor meant to drive a pump. This coupler allowed me to easily retrofit a conventional 5/8 keyed shaft and pulley to the motor. It fits precisely and runs true. Thank you!

Used this to extend the shaft of a motor. It fits tight and holds securely.

It is a good product but I need different sizes on both ends an you don't have it. I like ordering from you I always get my things thanks
