The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. They're also known as spur gears.

For smooth, quiet operation at high speeds under heavy loads, helical gears have curved teeth that engage gradually and stay in contact longer than straight teeth.

With straight, conically shaped teeth and a 1:1 speed ratio, miter gears connect two shafts at a right angle without changing shaft speed or torque. They're more efficient than spiral miter gears because they create less friction.

Also known as spiral miter gears, these gears have curved teeth that gradually engage and stay in contact longer than straight teeth so they handle heavier loads at higher speeds. Speed ratio is 1:1.

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

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.

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.

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

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

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

Made of aluminum, these pulleys have good corrosion resistance.

Anodized aluminum has good corrosion resistance.

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

To prevent slippage while moving extra heavy loads, these pulleys mount with a bushing for a more secure grip on the shaft than set screws and press-fit pulleys.

Made of iron, these pulleys are strong enough to carry extra heavy loads.

For higher speed or higher torque applications, these GT series timing belt pulleys provide a more precise fit than HTD pulleys. Use them where accuracy is critical, such as in storage and retrieval systems or in robotics.

Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built-in, free-spinning ball bearings, they're installed on shafts or belt tensioners to remove slack from timing belts.

Mount these high torque drive (HTD) pulleys onto a hex shaft.

Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft.

These pulleys have the same sizing versatility as quick-disconnect pulleys, but they create a tighter grip on bushings for use in high-torque applications.

These pulleys are cast iron.

Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys.

These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration.

Also known as paper-plant pulleys, these are made of a paper-fiber composite that minimizes belt slippage and wear.

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

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

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

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

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

The double row of teeth on these sprockets are designed to fit into metric ISO double-strand roller chain.

Machine the center of these sprockets to fit the exact dimensions of your shaft. The teeth are sized to fit into metric ISO 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.

The teeth on these sprockets are sized to fit Harsh Environment Flat-Edge Roller Chain.

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

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

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

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

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

Adjust shaft speed and torque for use in low-speed, high-torque applications.

Mount these speed reducers to a NEMA 56C motor.

Mount right-angle speed reducers to machinery or other surfaces where access from the bottom is not possible.

With a sanitary design for food-processing environments, these speed reducers mount to the face of your motor—no coupler required—to slow shafts and increase torque while transmitting motion at a 90° angle.

For small machinery and tight spots, these gear boxes have 1/4" diameter and smaller shafts and a footprint of less than 2½" square.

With shaft diameters of 3/8" and larger, these gear boxes transmit higher speeds and greater torque than Compact Right-Angle Gear Boxes.
