New manufacturing technology
utilizing a Face Hob Process which
features a single pass pinion tooth
machining operation compared to a
conventional three pass process for
machining. CNC cut and lapped gear
teeth. Higher strength and better
quality gears are produced with the
Face Hob Process. NOTE: These new
gears look a little different; the gear
teeth are cut on a different angle and
the ring gear has a bevel on the back
of the gear.
