Hey Vac, funny you should post about this. Tonight I was showing a friend the bearings and he said, why didnt I just bolt two bearings together with a washer seperating them. Now I feel sick.
I dont know how the bearings would wear with the force on the side pushing them apart though.
Yes I did think of your idea too, but dont have a lathe to make the wheels. I could have almost bought a lathe at those costs though, and I would have got to keep the lathe. You see this is why the forum is so good, others can learn from others mistakes.
Oh and just remember you are quoting Aussie dollars and not US dollars. US dollars would be about $500 for the same thing. Just been pedantic to make myself not feel so bad. Truthfully I am still happy I didnt pay much more for proper linear bearings though.
EDIT: Your design is better than the bearings I bought, not only because it is cheaper but because the load is spread over two bearings and not one. |
