Product Description
Spur gear module 1.5, z=65, with hub
The spur gear module 1.5 shown, 65 teeth, with hub, is a basic component of module drives - it meshes with any other gear or gear rack (toothed rack) of the same module and pressure angle 20°. Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Frequently asked questions
How does a module gear differ from a chain sprocket?
A module gear meshes directly with another gear or gear rack, while a sprocket works with a roller chain - they have a different tooth profile and are not interchangeable, even though they look similar from a distance.
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 module gear require constant lubrication?
Enclosed gears (in speed reducers) run in oil or grease, while open systems (gear + rack) require periodic manual lubrication - without it, friction and tooth wear increase many times faster.
How do you calculate the ratio of a gear pair of two module gears with different numbers of teeth?
The ratio is calculated as the quotient of the number of teeth of the driven gear to that of the driving gear (i = Z2/Z1); the module must be identical for both gears, otherwise meshing will not work at all.
Where is this product used?
Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.
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.
