Bevel and miter gears have conical faces that operate on intersecting axes.

Protractors and angle gages measure the angle between two surfaces of a part or assembly.

Hypoid gears have specially formed teeth on a circular face that are driven by a worm-like drive on non-intersecting axes.

Gaskets are used to prevent fluid or gas leaks by providing a barrier between two mating surfaces.

Gears are mechanical devices that transmit power and motion between axes.

Gearboxes and gearheads are speed reducers that consist of a set of gears, shafts, and bearings in an enclosed housing.

Metric gears are defined by module, which designates the center-to-center distance between successive teeth.
