Gears

Simple construction, easy to manufacture, exact ratios and high efficiency, with no axial thrust. Suited to low- and medium-speed, light-to-medium-power drives between parallel shafts — gearboxes, machine tools and automation equipment.

High contact ratio for smooth, quiet running, high load capacity and long service life (generates some axial thrust in operation). Suited to parallel-shaft drives with frequent starts, medium-to-high speed and a wide power range where low noise and smooth motion are required.

Simple construction, easy to machine and install, exact ratios and lower cost. Suited to medium- and low-speed drives between intersecting shafts (typically 90°) across a wide power range — differentials, agricultural and general machinery.

Curved teeth with more teeth in mesh — smooth, quiet running, high load capacity and long service life. Suited to intersecting-shaft drives with frequent starts, frequent forward/reverse changes, medium-to-high speed and a wide power range, such as automotive final drives and precision machinery.
