Product Description

By entering your model number, you can make sure that this fits.

Provides rotational power to another part of a motorized system by transmitting torque between parallel shafts.

A 20-degree pressure angle results in a lower contact ratio between gears and therefore a higher load capacity than smaller pressure angles.

Diametral pitch of 20 for applications that necessitate a delicate balance between transferring torque and precisely controlling changes in rotational speed and direction.

Steel with low carbon content (. 2 percent carbon) for applications where higher levels of carbon's hardness and strength aren't required to transmit torque and motion.

Questions & Answers

Is this gear compatible with a r2020x4 20pa 1/2"x1/2"x4' rack?

Yes, the DP and pressure angles correspond, and they are compatible.

Will this fit on a 12mm shaft with acceptable tolerances?

The YA20 has a 1/2 bore and is made of steel. It does not have a keyhole. On the bore, there is a tolerance of -. The 12MM shaft should have a diameter of 0 millimeters. 4724 +- tolerance is an important factor. As a result, it will be able to slide onto the shaft. It's difficult to predict whether or not it will be too costly; it all depends on the application. Best of luck to you.

Is there a way to do this? Yes, as shown in the photo, but no, as shown in the dwng. ?

There is no keyway on the YA20. To order gear with a keyway, add the bore designation to the part number (i.e., i.e., i.e., i.e., i.e., i.e., If you're looking for a 0 score, you've come to the right place. YA20- is the part number for a 5 inch bore with keyway and setscrew. 1/2).

What is the Diameter of the Pitch? This information is crucial in the description of spur gears. ?

One inch is the pitch diameter.

There isn't a set screw or a keyway! They appear to be in good condition on the whole

4/5

Both the keyway and the set screw are shown in the photos in the offer. I ordered three gears, but only two have arrived so far, in two separate shipments. I'm going to keep them and drill and thread one set screw into each of them. I am confident that they will function properly on the CNC plasma cutter that I am constructing. I'm just hoping that the seller ensures that I get the third one, and that future buyers are aware of what they're purchasing! br>br>nine br>br>nine br>br>nine b I've got the third gear now! I'm going to put them to good use.

We are a manufacturing company with over 400 production machines, so how quickly can we get the part? It's difficult to always know what parts to stock, so when a machine breaks down, we have to scramble to find replacements

5/5

You're either lucky or unlucky at times. The timing in this case was extremely tight. Thank you very much!.

NOT IN THE WAY THAT IT HAS BEEN DESCRIBED

3/5

There isn't a set screw or a keyway. How can a seller not address this, as I've seen others do?.

NOT IN THE PHOTO- There is no set screw on this item

3/5

The set screw is depicted on Amazon's website, but it is not included. I'd return it, but I can't seem to find anything comparable, so I'm going to try drilling and tapping a hole in it and inserting a set screw (or two). Aside from that, it appears to be an attractive piece of equipment. br>br>Unlike ebay, where contacting a seller is simple, I can't seem to find a way to contact a live person. So I guess the only options are to return it or keep it, which is a bit of a pain.
