Product Description

Spur gear module 4, z=56, with hub

This module 4 spur gear (56 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.

Technical data

Frequently asked questions

Do straight-tooth module gears have a specific mounting direction?

No, a straight-tooth gear is symmetrical and can be mounted either way round; direction only matters with helical teeth, where the helix angle must match the mating gear.

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.

Why is the pilot bore in a module gear often smaller than required?

A "rough" bore allows you to bore it out yourself to the exact, non-standard size of the customer's shaft - a ready-made large bore from stock would rarely match the required size perfectly.

Can gears with different modules be combined in one gearbox?

Absolutely not. Teeth of different modules differ in size and pitch. Any attempt to mesh them will end in the drive jamming or the teeth breaking off immediately on the first revolution of the shaft.

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.
