    High-Power Metal Helical Gears

    The helical teeth on these gears stay in contact longer than straight teeth, which allows them to transmit higher loads at higher speeds than spur gears.
    Crossed Gears
    Image of Product. Front orientation. Helical Gears. High-Power Metal Helical Gears, Crossed Gears.
    Crossed helical gears, also known as screw gears, can be configured to transmit motion at a 90° angle or in a straight line. To transmit motion at a 90° angle, pair two gears with the same tooth direction. To transmit motion in a straight line, make sure to get one left-hand and one right-hand gear.
    For gears to mesh correctly, they must have the same pressure angle and pitch/module. To change speed and torque in your assembly, pair two gears with different numbers of teeth.
