Spiral bevel gear is a bevel gear with helical teeth.  The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth.

A spiral bevel gear set should always be replaced in pairs i.e. both the left hand and right hand gears should be replaced together since the gears are manufactured and lapped in pairs.

Spiral bevel gears require a specific machine to produce.
