Creating a joint between a shaft and a bearing

I started using Fusion 360 about a week ago and I've been watching videos, reading tutorials, and learning about the program. I can not figure this out, but I know I must be missing something obvious.

 

I am trying to align a bearing to a point that is 15 mm from one side of a shaft. At first, I thought I needed to align the inner race of the bearing with the outer diameter of the shaft and then align the bottom of the shaft with the bottom face of the bearing. At that point, I would be able to move the bearing by 15 mm in the +Z direction to get it into the right location. However, I am realizing that is most likely not the right way to do it after spending a lot of time trying to make it happen.

 

I've been trying to use the joint tool to accomplish this task after finding similar questions on the forums. I have been able to get the bearing aligned with the shaft in one dimension, but not the other. Even so, I would like to eventually simulate and animate the assembly, so I know joints need to be defined. I simply don't understand what I'm doing wrong or if I'm even approaching the problem the right way. Here is a picture of my drawing:

In short, how do I get the bottom of the bearing to be joined 15 mm from the bottom of the shaft? Thanks.

Joints work with Components.  Components must be holding your body/s.

Bearing in one Component, the Shaft must be in a separate Component.

 

Joint Tool will show snap points that can be confirmed for the disc position.  You were close, yes centre face snap points then 15mm offset along the shaft.  Joint discs will mate flush, So orientation of the disc is important in other cases.

 

Might help....

Thank you for taking the time to respond. I appreciate it.

 

Perhaps I should have shown more context in my editor. Here is how everything looks at the moment:

My intention was to create components and then assemble them, but maybe I'm not using the right words and/or features of Fusion 360. Does what you said match what I've done or do I need to start over?

Your Browser is perfect, and as such, Joints should work as expected, after placing the shaft anywhere.  Your Bearing needs to be Grounded.  Then I would expect the shaft to behave.

 

When inserting your parts, you are given the Move Tool to place for position at the time of insert, you could have that placement achieved at the time the shaft is Inserted, without a Joint.  

 

However since the design requires the Joint later, best you try a Joint again.

 

Might help....

Take a look at the Screencast.  I used a bearing that is a single component, yours is a sub-assembly but that makes no difference.  You are also using Linked Components where mine are included in the assembly, that also makes no difference.

John - Thank you for taking the time to show me a screencast and, also, thank you for showing me screencasts. I downloaded the tool to create my own screencasts so I can post more informative questions when I inevitably get stuck.

 

The step by step explanation was extremely helpful. I have a lot to learn as I don't know the differences between included and linked components, but I am researching that plus many of the other things you mentioned in the screencast as I write this. Thank you so much for the help.
