About Roller Chain and Sprockets

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

This treated steel chain has over eight times the capacity of stainless steel chain.

Ultra-Corrosion-Resistant ANSI Roller Chain and Links

Made of 316 stainless steel, this is our most corrosion-resistant 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.

Maintenance-Free ANSI Roller Chain and Links

With oil-embedded bushings and oil-coated pins, this chain is self-lubricating, which means it requires less maintenance than standard ANSI roller chain.

Extended-Life Maintenance-Free
ANSI Roller Chain and Links

A rubber ring seals grease between the bushings and pins and keeps out dust and other contaminants.

Corrosion-Resistant Maintenance-Free
ANSI Roller Chain and Links

This self-lubricating nickel-plated steel chain has better corrosion resistance than steel chain and does not require regular maintenance.

Double-Pitch ANSI Roller Chain and Links

This chain is made of steel.

Corrosion-Resistant Double-Pitch
ANSI Roller Chain and Links

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

High-Strength Corrosion-Resistant
Double-Pitch ANSI Roller Chain and Links

This treated steel chain has over six times the capacity of stainless steel chain.

Hollow-Pin ANSI Roller Chain and Links

This steel chain handles higher loads than stainless steel chain.

Corrosion-Resistant Hollow-Pin
ANSI Roller Chain and Links

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

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.

Double-Pitch ANSI Roller Chain Attachment Links

Twice as long as standard links, these are designed for use with Double-Pitch ANSI Roller Chain.

ANSI Attachment Chains

Attach brackets and guides to these chains—or move material directly—for use in conveying, timing, and aligning applications.

Jaw-Style Roller Chain Holders

Hook into your roller chain and use the handle to tighten the jaw until the chain ends are close enough to add or remove a link. Choose from holders with maximum jaw capacity from 1 3/4” to 5”.

Roller Chain Breakers

Drive out chain pins with a twist of the handle.

Wrench-Drive Roller Chain Breakers

Tighten the hex head screw with a wrench to remove chain pins without damaging side plates.

Center-Channel Roller Chain Guides

These guides align chain more precisely than open-channel guides.

Open-Channel Roller Chain Guides

Minimize friction, reduce noise, and prolong the life of your roller chain. Guides can be cut to the exact length you need.

Deep-Channel Roller Chain Guides

Also known as captured guides, deep-channel guides prevent chain from slipping off track.

ANSI Roller Chain Wear-Indicating Rulers

Place these plastic rulers on links to measure chain wear.

ANSI Roller Chain Wear-Indicating Inserts

Place these steel inserts between two roller links. If they can be inserted past your ANSI number, the chain is worn out.

Tensioners for Chain and Belt Drives

Floating Roller Chain Tensioners

Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension.

Roller Chain Tensioning Rings

Install these rings between strands of chain to absorb slack without the need for realignment, lubrication, or tools—good for use in confined spaces where maintenance may be difficult.

Channel-Guided Roller Chain Tensioners

These tensioners range in height from 5 15/32" to 7 25/32".

Low-Profile Channel-Guided Roller Chain Tensioners

At less than 4" in height, these tensioners are good for use on low-clearance drives.
