Product Description
Spur gear module 2, z=66, with hub, hardened
This module 2 spur gear (66 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The teeth are induction hardened to 45-55 HRC, which significantly increases wear resistance and extends gear service life in heavily loaded transmissions.

Frequently asked questions
Can a module gear be ordered with a number of teeth outside the standard catalogue range?
Yes, in addition to ready stock we also produce CNC gears to order with a non-standard number of teeth, and for short lead times we additionally print them using 3D technology from glass-fibre-reinforced plastics.
Can module gears be bored out for non-standard shafts?
Yes, most module gears are supplied with a pilot bore, which allows them to be freely bored out, keyway-slotted and precisely fitted to the specific shaft size at the customer's premises.
What lubrication is optimal for open module (rack) gear drives?
For open systems (gear + gear rack), it is best to use thick greases with added graphite or copper, which adhere firmly to the teeth and are not flung off by centrifugal force. In very dusty applications, dry Teflon lubricants perform better.
Does a higher number of teeth (z) with the same module mean a stronger gear?
Not directly - tooth strength depends mainly on the module and face width, not on the number of teeth; a larger z with the same module simply gives a larger gear diameter and a higher ratio relative to the mating gear.
Where is this product used?
Module gears of this type are used in speed reducers, machine gearboxes, CNC machine tools and in rack drives of sliding and entrance gates.
When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
