Module 3 spur gears with hub

Module 3 spur gears with hub are designed for conveyor, lift and machine tool drives. They are straight-tooth cylindrical gears with a pitch of 9.42 mm, with a hub that allows mounting directly on the shaft.

Module 3 spur gears with hub - considerable loads and convenient mounting

Module 3 already transmits considerable loads while remaining convenient to install. You can choose the gear exactly for the operating conditions: standard in C45E steel, with hardened teeth for intensive work, stainless for damp conditions, or PA6+FV polyamide when quiet running and low weight matter. You bore out the pilot bore for your shaft and add a matching keyway. 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.

Module 3 pinions with hub: C45E steel, hardened, stainless and PA6+FV

Module 3 gears with hub with a 20° profile and a wide choice of tooth counts. Dimensions are given on the product page, and large gears without a hub can be found in the Plate spur gears - module 3 group.

Frequently asked questions about module 3 spur gears with hub

How does a PA6+FV gear differ from a steel one?

Glass-fibre reinforced polyamide is lighter, runs more quietly and does not corrode, but it carries lower loads than steel. It works well in lighter drives and where noise matters.
