Angle Gears | McMaster-Carr

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.

Metal Worms and Worm Gears

Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.

Metal Bevel Gears

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.

High-Power Metal Miter Gears

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.

High-Power Metal Bevel Gears

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.

High-Power Metal 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.

Plastic Gears and Gear Racks

Plastic Miter Gears

Connect two shafts at a right angle without changing shaft speed or torque.

Plastic Worm Gears

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.

Plastic Bevel Gears

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.

High-Power Plastic Gears

Transmitting loads at higher speeds than spur gears in environments where rusting and exposure to chemicals is a concern, these plastic gears have helical teeth, which stay in contact longer than straight teeth. They’re often called screw or crossed-helical gears.
