Gears

Gears are essential mechanical components used to transmit motion, torque, and power between rotating shafts in various industrial applications. Available in types such as spur, helical, bevel, worm, and planetary gears, they are widely used in industries like automotive, aerospace, robotics, and manufacturing. The selection of gears depends on factors like load capacity, gear ratio, efficiency, and noise requirements.
