Taper-Lock Bushing-Bore Sprockets for ANSI Roller Chain
Get the same sizing versatility as quick-disconnect sprockets while using less space. The bushings for these sprockets mount flush inside the sprocket hub for a slim profile. The same sprocket can be used with different shaft diameters; choose a compatible taper-lock bushing with the bore size you need.

Split-Tapered Bushing-Bore Sprockets for ANSI Roller Chain
Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications. The same sprocket can be used with different shaft diameters; choose a compatible split-tapered bushing with the bore size you need.
Sprockets for P1- and Q1-Style bushings have a keyway that fits a matching key on the bushing.

Taper-Lock Bushing-Bore Sprockets for Metric Roller Chain
While their teeth fit into metric ISO roller chain, these sprockets use taper-lock bushings to grip shafts. That means you can switch to a different diameter shaft by changing the bushing instead of machining the sprocket. Bushings mount flush inside these sprockets; secure them in place by tightening the set screws included with the bushings. These sprockets have an extended hub that makes them more stable and durable than flat sprockets. All meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.

Flat Taper-Lock Bushing-Bore Sprockets for Double-Strand Metric Roller Chain
With a slim profile and a double row of teeth, these sprockets allow your metric ISO double-strand roller chain to fit into tight spaces. They’re often called A-plate sprockets. To grip shafts, they use taper-lock bushings, so you can switch to a different diameter shaft by changing the bushing instead of machining the sprocket. Bushings mount flush inside these sprockets; secure them in place by tightening the set screws included with the bushings. All of these sprockets meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.
