Shop Around

Needed an Auger Bearing for a Craftsman Snowblower......


Bearing and Retainer Assembly | Part Number 761508MA | GUARANTEED FIT from Sears PartsDirect




Ebay Bearing Worked Fine for Under $10 Shipped.I did Have to Knock the Bearing out of the carrier and get Measurements. All of 5 minutes work.

Gotta be some difference in them for that price difference. At least you'd think there'd be.
But you're very correct. I see stuff like this all the time. ... And folks pay it too.

Did you get it with the same key-way?

That sort of key-way in the bearing is an oddity that takes it out of the commodity realm. It may be a catalog time but 36 years in bearings catalogs says they are not common stock. Add the housing put it in an OEM part supply chain with a few folks needing to make money along the way and there you have it.

If you said to heck with the key then it's not apples to apples but if it's good enough for you then good luck.

Wow, that's about how much a replacement bronze bushing was for the idler pulley on my old Ariens!
I fixed it myself with a $2 piece of bronze sleeve that I bought at a hardware store.

Sears parts direct is never my first choice for purchasing. I like it to see diagrams and find part numbers but searching for a deal isn't that hard with a little time at the keyboard.

I saw No Advantage to the Keyway in the bearing, but saw an advantage in saving $60. Only needed to use a shorter key to hold pulley. Not about "Luck", just Economics and Common Mechanical Sense.

I sounds like the design advantage of the key was to keep the inner race of the bearing turning with the shaft. This means that when the bearing fails it will fail within itself unless ignored for a long time. Lacking the key (other engagement) a failing bearing can start to spin on the shaft and shred the shaft ruining it for future use. Loctite or a tight fit can help but they won't be as positive.

Cheaper yes, good enough for the machine at this stage, probably but a design compromised, certainly.

Ariens, Toro, Mtd, see no need for a key in their auger bearings, either. Your Opinion has been Noted and Filed in the Correct Receptacle.
