This little pulley’s a beast.

It’s a 5.6 inch single groove sheave with a 5/8 inch bore — model AK56 or AK5658 depending on how you search it.

Brand’s RBO, color’s that industrial gray, and it’s designed for A-section belts.

Whether you’re building a rig or replacing a worn-out part, this one’s ready to spin.

New, never used, still in the packaging.
Oh, and California Prop 65 warning applies — just a heads-up.
No MPN, no UPC, just a solid single groove pulley that does what it’s supposed to.

One groove, no teeth, straight to work.
