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

Spur Gear Racks

Spur Gear Racks

Pair with a spur gear to convert rotary motion to linear motion

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

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

Helical Gears

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