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.

Compared to plastic gears, metal gears are better for high-load, high-speed, and heavy duty applications.

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.

Three rows of teeth make these sprockets compatible with triple-strand ANSI roller chain.

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

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 for a custom fit that matches your shaft. The teeth are sized to fit into silent-drive chain.

These sprockets are made of steel.

Keep constant tension on your drive with these sprockets that press against your metric ISO roller chain to take up slack and reduce wear and vibration.

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

Use these sprockets with compatible QD bushings.

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

Pulleys are XL series (extra light) and have trapezoidal teeth.

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

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

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