Specifications and dimensions

The source item code contains HRC. This specifies neither a numerical hardness, its tolerance nor the processing method — check the requirements of the specific machine.

Selection and applications

Compare the module, number of teeth, bore, face width and available mounting space. Overall width A includes the hub and is not the same as face width B. The module alone does not confirm full interchangeability; also check the pressure angle, accuracy, tolerances and required shaft mounting method. The source does not specify these parameters. We do not claim an unconfirmed keyway or additional fastenings.

Frequently asked questions

What does M4 Z12 mean?
M4 denotes module 4, and Z12 a count of 12 teeth.

Is this a sprocket?
No. The cylindrical module gear is used in gear drives, rather than with a chain.

How should the drawing be read?
d is the bore, D is the hub diameter, Dp is the pitch diameter, De is the outside diameter, A is the overall width and B is the face width. The drawing shared by the group shows the measurement locations; confirmed values are in the table. It does not mean the source provided all dimensions.

What are the minimum quantity and fulfilment time?
Minimum 1 piece, fulfilment within 48 hours. This is not a guarantee of delivery by the carrier.
