About Roller Chain and Sprockets

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

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

Wear-Resistant Sprockets for ANSI Roller Chain

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

Corrosion-Resistant Sprockets for ANSI Roller Chain

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

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.

Lightweight Sprockets for ANSI Roller Chain

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

Flat Sprockets for ANSI Roller Chain

Also known as A-plate sprockets, these have a slim profile that fits in narrow spaces.

Sprockets for Double-Strand ANSI Roller Chain

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

Idler Sprockets

Idler Sprockets for ANSI Roller Chain

These sprockets are made of steel.

Wear-Resistant Idler Sprockets for ANSI Roller Chain

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

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

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

Wide-Hub Idler Sprockets for ANSI Roller Chain

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

Idler Sprockets for Double-Strand ANSI Roller Chain

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

Use these sprockets with compatible QD bushings.

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

Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications.

ANSI Roller Chain and Links

Roller chain links engage with matched sprocket teeth to transmit power between rotating shafts.

Heavy Duty ANSI Roller Chain and Links

Thick side plates allow this chain to handle greater capacity than standard chain.

Corrosion-Resistant ANSI Roller Chain and Links

This 304 stainless steel roller chain is more corrosion resistant than treated steel roller chain.

High-Strength Corrosion-Resistant
ANSI Roller Chain and Links

Treated steel chain has over eight times the capacity of stainless steel chain.

Lightweight ANSI Roller Chain

This acetal chain is suitable for general purpose applications.

Extended-Life Lightweight ANSI Roller Chain and Links

Plastic bushings as well as stainless steel pins and outer side plates give this chain a longer service life than other lightweight chain.

Chemical-Resistant Lightweight ANSI Roller Chain

Commonly used in chemical manufacturing, paper pulping, and waste processing, this chain is made of PVDF.

Ultra-Flexible ANSI Roller Chain and Links

Also known as side bow chain, this chain has extra clearance between components for flexing from side to side on systems with curved tracks and sprockets that aren’t exactly aligned.

ANSI Roller Chain Attachment Links

These links are made of steel.

Corrosion-Resistant ANSI Roller Chain Attachment Links

Made of treated steel, these links offer increased corrosion resistance over steel attachment links.

Metric Roller Chain and Links

This chain is made of steel.

Corrosion-Resistant Metric Roller Chain and Links

Made of stainless steel, this chain has excellent corrosion resistance.

Timing Belts and Pulleys

L Series Timing Belt Pulleys

These L series (light) pulleys and have trapezoidal teeth.

L Series Corrosion-Resistant Timing Belt Pulleys

Pulleys are anodized aluminum, which is more corrosion resistant than steel.

L Series Quick-Disconnect Timing Belt Pulleys

Carry heavy loads without slippage—pulleys mount with a bushing for a more secure grip on the shaft than set screws.

Timing Belt Idler Pulleys

Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out.
