H Series Timing Belt Pulleys

H Series Timing Belt Pulleys

Pulleys are H series (heavy) and have trapezoidal teeth.

Gears and Gear Racks

Metal Gears and Gear Racks—
14 1/2° Pressure Angle

testString

A former industry standard, 14½° pressure angle gears are often found on older machinery.

Metal Gears and Gear Racks—20° Pressure Angle

testString

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.

Metal Miter Gears

testString

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

testString

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

Plastic Gears and Gear
Racks—14 1/2° Pressure Angle

testString

A former industry standard, 14½° pressure angle gears are often found on older machinery.
