22 Teeth Sprockets | McMaster-Carr

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.

Bushing-Bore Sprockets

Quick-Disconnect (QD) Bushing-Bore
Sprockets for ANSI Roller Chain

Use these sprockets with compatible QD bushings.

Taper-Lock Bushing-Bore
Sprockets for ANSI Roller Chain

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

Split-Tapered Bushing-Bore
Sprockets for ANSI Roller Chain

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

Taper-Lock Bushing-Bore
Sprockets for Metric Roller Chain

While their teeth fit into metric ISO roller chain, these sprockets use taper-lock bushings to grip shafts.

Timing Belts and Pulleys

L Series Timing Belt Pulleys

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

L Series Corrosion-Resistant Timing Belt Pulleys

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

L Series Quick-Disconnect Timing Belt Pulleys

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

XL Series Corrosion-Resistant Timing Belt Pulleys

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

XL Series Lightweight Timing Belt Pulleys

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

XL Series Timing Belt Pulleys

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

H Series Timing Belt Pulleys

Pulleys are H series (heavy) and have trapezoidal teeth.

H Series Quick-Disconnect Timing Belt Pulleys

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

MXL Series Corrosion-Resistant Timing Belt Pulleys

Anodized aluminum has good corrosion resistance.

MXL Series Lightweight Timing Belt Pulleys

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

Timing Belt Idler Pulleys

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

High-Strength Timing Belts and Pulleys

High-Strength HTD Timing Belt Pulleys

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

High-Strength Corrosion-Resistant
HTD Timing Belt Pulleys

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

High-Strength GT Timing Belt Pulleys

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.

Ultra-High-Strength Poly Chain Timing Belt Pulleys

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.

Gears and Gear Racks

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

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

Metal Gears and Gear Racks—20° Pressure Angle

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.

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.
