Selection and applications

When selecting for machine mechanisms, drives and positioning systems, compare the module, number of teeth, face width, bore and available mounting space. The hub increases the overall width to 35 mm — this must not be confused with the face width of 20 mm. The mating gear or rack must have a matching module and the other tooth parameters required by the gear design.

Matching the module alone does not confirm full interchangeability. The source does not specify the pressure angle, accuracy grade, bore tolerance or numerical hardness. Before purchasing for a specific machine, check these requirements in its documentation. Select the shaft mounting method separately; we do not claim unconfirmed keyways or fastenings.

Frequently asked questions

What does M2 Z20 mean?
M2 specifies module 2, and Z20 denotes a tooth count of 20. The pitch diameter Dp of this variant is 40 mm.

Is this a sprocket?
No. This is a cylindrical gear with straight teeth for gear drives, rather than a sprocket for use with a chain.

Does the gear have a hub and hardened teeth?
Yes. Variant M2 Z20 HRC has a hub and hardened teeth. The HRC designation in the item code is not a specific hardness value.

What do the drawing labels mean?
d is the bore, D is the hub, Dp is the pitch diameter, De is the outside diameter, A is the overall width and B is the face width. The values are in the table above.

What are the minimum quantity and fulfilment time?
You can order 1 piece. Fulfilment within 48 hours; this does not guarantee the carrier's delivery time.
