Product Description
Spur gear module 1, z=37, with hub
This module 1 spur gear (37 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Frequently asked questions
What is backlash and why does it matter?
It is a small gap between mating teeth, necessary for lubrication and thermal tolerance; too little backlash leads to seizing and overheating, while too much leads to jerking and faster tooth wear.
What is the module of a gear and how do you measure it correctly?
The module (m) is the basic parameter defining tooth size, i.e. the ratio of the pitch diameter to the number of teeth. The simplest way to measure it in workshop conditions is to measure the outside diameter of the gear (Dz), count the teeth (Z) and use the formula: m = Dz / (Z + 2).
How should gears be stored correctly before installation?
Preferably in a dry room, protected against moisture and dust, with a light layer of preservative oil on the teeth and bore - especially important for C45E carbon steel, which can start to corrode without protection.
How can a module gear be secured against sliding along the shaft?
Besides a key or a clamping bush, set screws (locking screws) in the hub, thrust washers or retaining rings are also used - the choice depends on whether the transmission operates under variable axial load.
Where is this product used?
Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
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.
