bearings

[B Oeuf]

Had to replace the drum in our washer this weekend and was surprised to see they were ball bearings......I'd have thought roller bearings would have suited this application better

If they last the warranty period it doesn't matter about suitability.

It's all down to the manufacturing costs.

Yep.

Why make them bomb proof? That just means it will be ages until you buy another. Built in obsolesence.

Surely as the bearing is at the back, assuming you haven't got a twin tub, then there will be at least some thrust load on the bearing. So you either fit two bearings, one roller and one thrust, or you fit a deep groove ball bearing and every ones a winner. If you do have an upright then yes a roller thust bearing would seam a better choice. If you are on about opposed tapper rollers then yes that would be a good solution but would you want to pay for it?

the axle is about 5" long with a bearing at either end so purely radial load I'd have thought. Is a roller bearing that much more expensive thasn a ball bearing?
