Sleeve vs Ball Bearing motors

The comparison of a furnace blower motor to a washing machine motor is likely invalid due to radial bearing loading.

Aren't most all semi-recent furnace blowers direct drive? A sleeve bearing can last in that application, but when there is belt loading a sleeve bearing really seems like a cheap move.

That comparison was a little off. However on the SQ the spring is very weak, so I think it is ok.

Give me ball bearings any day!

Sleeves are ok for light duty intermittent stuff, but ball bearings are the bees knees for durability!

Even the older belt driven furnace motors where mostly sleeve bearings. The Maytag helical drive upper sleeve bearings held up very well. Unless the seal leaked but that ruins a ball bearing also.

"Sleeve" bearings can be more durable than you think--just keep them properly lubed.Example of an extreme sleeve bearing-fossil fuel power plant steam turbine genset-These use sleeve bearings that have pumpted lubrication.The lube also serves as a seal to keep the steam in the turbine and the hydrogen cooling gas in the generator!And keep in mind those bearings are supporting a turbine/gen rotor that can weigh 100 tons and turns at 3600 RPM!!!Nuke plant rotors even larger-but turn at 1800 RPM.

Thanks for the Shoutout!

The outer tub in my 150 Blackstone is a painted wonder that hasn't a speck of rust or corrosion anywhere, even after all these years (1950).
