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.

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.

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.

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

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

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

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

Made of aluminum, these pulleys have good corrosion resistance.

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

Teeth are curved and set in an offset pattern for high strength with 25% less operating noise than pulleys and belts with trapezoidal teeth.
