Spur Gears

The simplest type of gear for transferring motion, with straight, parallel teeth

Spur Gear Stock

Spur Gear Stock

Machine your own gears to an exact face width and shaft diameter

Internal Spur Gears

Internal Spur Gears

Teeth on the inside mesh with standard spur gears to save space

Worm Gears

Reduce speed while transferring motion at a right angle in only one direction

Miter Gears

Connect shafts at a right angle without changing speed or torque

Helical Gears

Curved teeth stay in contact longer to transmit heavier loads at higher speeds than spur gears

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

Bevel Gears

Reduce speed while transmitting motion at a right angle
