  • Yeah, main bearings on car, like crankshaft and cam are solid bearings and journals. Wheelbearings are a timpkin flat roller, I think, to support a lot of load and thrust. They are packed and sealed. But if it isn’t heat, then I would say the part size just gets big when you need an inner race (around shaft), bearings , then outer race, housed in a bracket. Lot cheaper for just the sacrificial part, till the wear like you show starts affecting other parts.





  • Assumptions: For the size a bearing can handle load better, and can be a self lubricating material. Ball bearings are small contact points, and a lot of off center vibration of the machine might wreck the ball bearing. Especially if it gets warm and grease runs out. So they would need to have a much larger ballbearing race like you see on industrial machinery, and the cost probably doesn’t justify it.

    My dryer seals broke this year, in replacing them I could see why they wore through. The back of drum wheels are just bearings (no balls), the weight of drum had the wheel bearings wear a wide groove in the support shafts so it shifted everything. And front has no bearings it just rides on the seal. I rotated/swapped them all around so they start with a fresh wear face and replaced a wheel. It should support itself better. Maybe we will get 5 more years out of it.







  • That’s not accurate, that is repeating the line private places want you to say about provincial or national care.

    I had cancer. When test came back positive, they got me in the next week for surgery, then to the center to do the paperwork and scans and predental work. They then needed another week or two to have 3d scans used to define the radition paths for the machine, and set up hospital visits and chemo. I was done treatment in 2 months.

    The six month wait seems like BS unless you have a source.
