About Roller Chain and Sprockets

More

Sprockets for ANSI Roller Chain

Sprockets for ANSI Roller Chain

Sprockets for ANSI Roller Chain

Mount these sprockets onto your shaft and secure with a set screw—no machining necessary.

Machinable-Bore Sprockets for ANSI Roller Chain

Machinable-Bore Sprockets for ANSI Roller Chain

For a custom fit on your shaft, these sprockets can be machined to your exact specifications.

Machinable-Bore Corrosion-Resistant
Sprockets for ANSI Roller Chain

Machinable-Bore Corrosion-Resistant Sprockets for ANSI Roller Chain

For a custom fit on your shaft, these sprockets can be machined to your exact specifications.

Wear-Resistant Sprockets for ANSI Roller Chain

Wear-Resistant Sprockets for ANSI Roller Chain

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

Flat Sprockets for ANSI Roller Chain

Flat Sprockets for ANSI Roller Chain

Also known as A-plate and weld sprockets, these have a slim profile that fits in narrow spaces and are often welded directly to a shaft.

Sprockets for Double-Strand ANSI Roller Chain

Sprockets for Double-Strand ANSI Roller Chain

These sprockets have two rows of teeth for use with double-strand ANSI roller chain.

Sprockets for Two Single-Strand ANSI Roller Chains

Sprockets for Two Single-Strand ANSI Roller Chains

Reduce assembly time when setting up a system to drive two different roller chains from a single sprocket.

Sprockets for Triple-Strand ANSI Roller Chain

Sprockets for Triple-Strand ANSI Roller Chain

Three rows of teeth make these sprockets compatible with triple-strand ANSI roller chain.

One-Way Sprockets

One-Way Sprockets

default

Transfer power in one direction with these sprockets, which spin freely in the opposite direction.

Idler Sprockets

Idler Sprockets for ANSI Roller Chain

testString

These sprockets are made of steel.

Wear-Resistant Idler Sprockets
for ANSI Roller Chain

testString

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

Lightweight Idler Sprockets for ANSI Roller Chain

testString

Made of nylon, these sprockets are lightweight, quiet, and corrosion resistant.

Wear-Resistant Wide-Hub Idler
Sprockets for ANSI Roller Chain

testString

Hardened teeth give these steel sprockets increased wear resistance for a long service life.

Wide-Hub Idler Sprockets for ANSI Roller Chain

testString

A wide hub provides these sprockets with stability under heavy loads.

Idler Sprockets for Double-Strand ANSI Roller Chain

testString

These idler sprockets have two rows of teeth for use with double-strand ANSI roller chain.

Bushing-Bore Sprockets for ANSI Roller Chain

Quick-Disconnect (QD) Bushing-Bore
Sprockets for ANSI Roller Chain

Quick-Disconnect (QD) Bushing-Bore Sprockets for ANSI Roller Chain

Use these sprockets with compatible QD bushings.

Taper-Lock Bushing-Bore
Sprockets for ANSI Roller Chain

Taper-Lock Bushing-Bore Sprockets for ANSI Roller Chain

Get the same sizing versatility as quick-disconnect sprockets while using less space.

Split-Tapered Bushing-Bore
Sprockets for ANSI Roller Chain

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.

Taper-Lock Bushing-Bore Sprockets
for Double-Strand ANSI Roller Chain

Taper-Lock Bushing-Bore Sprockets for Double-Strand ANSI Roller Chain

Switch out the bushing to install these sprockets on shafts with different diameters—no machining necessary.
