The all new design of gear box iii Model PMW-R4OAA, R400 and P4OAA is having 9 speed with all 9 gears of hardened NiCr steel up to HRC 50-55. Oil bath gear box and hardened gears give very long life to the machine. Rotation and easy sliding of gears in bearings gives very high reliability. Gears are internally six splined and shafts are externally

All the gears in gearbox are machined on imported WMW Germany make gear shaper.

All the splines in the gear box are machined on imported PFAUTER Germany make spline milling machine.

Autofeed gear box used in Machine R4OAA, R4OBA & P4OAA is having gears made up of NiCr Steel & of heavy 2.5 module. All gears are also hardened. Two worm gears are of heavy duty 2.82 module teeth. All the shafts in the Gear Box are supported through good quality bearings and not the Bushes. Engaging of Autofeed through TAPER GONE MECHANISM as in the lathe machines enable maximum loading capacity leaving behind other machines.
