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.

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.

Also known as A-plate and weld sprockets, these have a slim profile that fits in narrow spaces and are often welded directly to a shaft.

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

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.

These sprockets are made of steel.

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

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

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 anodized aluminum, which is more corrosion resistant than steel.

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

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

These L series (light) pulleys and have trapezoidal teeth.

Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out.

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.

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

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

These HTD (high torque drive) pulleys have a curved tooth shape that provides higher strength than trapezoidal teeth.

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.

Choose from nylon, UHMW, and zinc.

Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove.

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

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.

Mount these pulleys directly onto a shaft to transmit rotary motion and torque.

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

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

Convert output drives from female to male.

The input and output shafts are positioned at the same height, so these speed reducers take up less than half the vertical space as our standard right-angle speed reducers.

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

Shaft diameters range from 5 to 35 mm.

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

For use in worm gears, this oil stands up to high pressure. Use it in food-processing and preparation areas where incidental contact with food is possible.

This oil withstands the heavy loads found in gear boxes.

Resistant to oxidation and heat, use this oil to lubricate a variety of machine tools and equipment. It's also known as turbine oil.
