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.

Made from carbon steel with spiral teeth, these gears handle heavier loads at higher speeds than bevel gears with straight teeth because their teeth stay in contact longer.

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.

When replacing a gear, use these gauges to identify pressure angle, pitch, and module.

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

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

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

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.

Made of aluminum, these pulleys have good corrosion resistance.

Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern.

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.

Curved teeth with a high pitch provide superior load distribution and reduce wear. They mount with a bushing for a more secure grip on the shaft than set screws.

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.

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

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

Designed to meet ISO 606 and DIN 8187 international dimensional standards, these sprockets are for use with compatible ISO and DIN roller chain.

With metric teeth and slim profile, these sprockets allow your ISO roller chain to reach narrow spaces. They're commonly referred to as A-plate sprockets.

These sprockets are made of steel.

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

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

Use these sprockets with compatible QD bushings.

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