Chain and Belt Drives

Lightweight Sprockets for ANSI Roller Chain

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

Sprockets for Miniature Roller Chain

Often used in electronic equipment, instrumentation devices, printers, and other compact machinery, these sprockets are made for use with our miniature roller chain.

Lightweight Idler Sprockets for ANSI Roller Chain

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

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.

Lightweight Miniature Roller Chain

This acetal plastic chain is light, quiet, and nonconductive. Its links snap together, so you don't need connecting links.

XL Series Lightweight Timing Belt Pulleys

Acetal and aluminum construction makes these pulleys useful in for weight-sensitive applications.

MXL Series Lightweight Timing Belt Pulleys

Made from polycarbonate, these pulleys are useful in applications with weight constraints.

Gears and Gear Racks

Plastic Gears and Gear
Racks—14 1/2° Pressure Angle

A former industry standard, 14½° pressure angle gears are often found on older machinery.

Plastic Gears and Gear Racks—20° Pressure Angle

The current industry standard, gears with a 20° pressure angle have thicker, stronger teeth than gears with a 14½° pressure angle.

Plastic Worm Gears

These plastic gears are lighter and quieter than metal gears—pair them with metal worms for lubrication-free operation. Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle.

Plastic Miter Gears

Connect two shafts at a right angle without changing shaft speed or torque.

Plastic Bevel Gears

Reduce speeds where noise, corrosion, and frequent lubrication are a concern. Compared to metal gears, these nylon gears run more quietly, won't rust, and don't need to be lubricated.

Plastic Ratcheting Gears

A light duty alternative to metal, plastic gears have good corrosion and chemical resistance.

Belt Conveyors

Sprockets for Conveyor Chain Belts

Sprockets transmit power to drive belting.

Conveyor Chain Belting

Also known as sprocket-driven conveyor belting, sprockets drive the belt.

Conveyor Wear Strip Rivets

Rivets attach plastic wear strips to the conveyor frame.

Wear Strips for Conveyor Chain Belts

Attach these strips to conveyor frames to reduce friction and abrasion on chain belts.

Sprockets for Food Industry
Cut-Resistant Conveyor Belting

Choose these sprockets when you need to expand your Ammeraal Beltech MPB conveyor line or replace its worn sprockets.

Idler Wheels for Conveyor Chain Belts

Idler wheels keep the belt moving and prevent sagging.

Modular Mini Chain Belt Conveyors

Build a mini conveyor in any shape you need. These conveyors have curved, straight, incline, and decline runs that you can quickly join together with the included brackets.
