Module 6 spur gears with hub

Module 6 spur gears with hub are heavy straight-tooth cylindrical gears with a pitch of 18.85 mm, designed for low-speed, high-torque gear drives. Paired with a module 6 gear rack, they drive linear axes with very high feed forces.

Module 6 spur gear with hub - the high strength of a large tooth

The large tooth provides high strength where smaller modules would wear quickly. The extended hub gives secure seating on the shaft and room for a keyway. We make the gears from C45E steel, and smaller driving gears also with induction-hardened teeth, which keep their profile longer under high contact pressures. O3D gears 3D printed from PA12 polyamide reinforced with chopped carbon fibre (PA12-CF15) are also available - lightweight, black as standard, and in other colours to order.
