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.
A former industry standard, 14½° pressure angle gears are often found on older machinery.
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.
Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.
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.
A type of miter gear where one gear is smaller than the other, bevel gears provide right-angle speed reduction at ratios ranging from 2:1 to 5:1. They’re more efficient than worm 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.
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.
Compared to plastic gears, metal gears are better for high-load, high-speed, and heavy duty applications.
Machine your own gears to fit the exact face width and shaft diameter required.
When replacing a gear, use these gauges to identify pressure angle, pitch, and module.
Mount these sprockets onto your shaft and secure with a set screw—no machining necessary.
For a custom fit on your shaft, these sprockets can be machined to your exact specifications.
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.
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.
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.
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.
Transfer power in one direction with these sprockets, which spin freely in the opposite direction.
The teeth on these sprockets are sized to fit Harsh Environment Flat-Edge Roller 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.
These idler sprockets have two rows of teeth for use with double-strand ANSI roller chain.
Use these sprockets with compatible QD bushings.
Get the same sizing versatility as quick-disconnect sprockets while using less space.
Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications.
Switch out the bushing to install these sprockets on shafts with different diameters—no machining necessary.
While their teeth fit into metric ISO roller chain, these sprockets use taper-lock bushings to grip shafts.
Pulleys are XL series (extra light) and have trapezoidal teeth.
These L series (light) pulleys 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.
Pulleys are H series (heavy) and have trapezoidal teeth.
Move heavy loads without slippage—pulleys mount with a bushing for a more secure grip on the shaft than set screws.
Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out.
These HTD (high torque drive) pulleys have a curved tooth shape that provides higher strength than trapezoidal teeth.
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.
Use these pulleys with compatible quick-disconnect bushings.
These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration.
