What are the size dimensions of the wheel-bearings?

My car is in serious need of front wheel bearings, and my problem is that I cannot afford them. So, I have a friend that's got totes full of different wheel bearings that he had when he ran his mechanic shop. So, he said if I could find out the size dimensions of bearing; the inside diameter and outer diameter and width of it. And/or a list of vehicles that the bearings are interchangeable with the car listed above SE. Please help!

Thanks in advance,
Olivia
