Questions & Answers
The ones I got from Amazon were rubber ones, but I don't recall who the supplier was.
nominally 75 or 3/4 inch or /- 3 1000th
This is a universal shaft that fits in most applications; it may need to be cut with a hack saw if it is too long; to determine the width of the shaft, measure across the center of the shaft. good luck

I'll begin with the package's arrival.
- Despite the fact that the items were sent Priority Mail, it took a week from the time the order was placed to receive them. Perhaps I've become "spoiled" by Amazon Prime's shipping.
- Although the spiders were well packaged, one of them was missing a bearing when I opened the box. I found the bearing and its packing/surround (the rubber/foam that keeps the bearing in the spider) at the bottom of the box after carefully going through the packing materials. This was the first time I realized how cheaply made the item was. Quality bearings of this type, on the other hand, have a semi-finished appearance. This one has a very soft foam instead of the hard rubber packings and surrounds. The packing on the bearing after it is installed in the spider is so loose that the bearing OD rotates freely in the spider. The oil cap/well is the only thing holding it back from fully rotating.
- My evaporative cooler (Kenmore model from the late 1990s) had no mounting holes that matched. Despite the fact that there are a number of pre-existing pre-existing pre-existing pre- The fan will not be centered when everything is put back together unless the drilled mounting holes in the spider match the existing holes on the individual unit. To get any new mounting holes in the unit exactly right, you'll either have to guess/eyeball it or do a lot of measuring and calculating. Thankfully, I was able to save the old spiders/bearings by aligning them with a 1" piece of shaft and marking/drilling new mounting holes in the new spiders. (NOTE: I strongly advise you to replace the shaft if it shows any signs of wear. If you don't, the new bearings will be ruined in no time. ) I built a new shaft for my unit the same day I ordered new bearings.
- It was a simple matter to install the new shaft and put everything back together once the new mounting holes in the spiders were drilled. I double-checked everything after a quick test run. Remember how I said the spider packing was a little soft and loose? I checked that the oil wells were centered in the spider hole(s) before installing the bearings. They shifted in the packing (in the rotational direction) once more. The oil well/cap is the only thing that prevents them from freely rotating. This MIGHT keep the cooler running for the rest of the season, but I'm not optimistic that it will. I would have gladly paid more for a higher-quality bearing, but what's a person to do when they check locally and find the EXACT same item for three times the price on Amazon?.
except for one thing. These bearings were made to fit perfectly with the help of a hack saw and some measuring. The structure appears to be quite sturdy. I'm not sure if it'll last as long as the original spiders did, but it's been a great summer so far. so good. Most cooler brands could probably be persuaded to use spider bearings, in my opinion. September br>br> Update on February 2, 2014: I have no idea what caused the issue. However, after a month of use, one of the Lasco spider bearings I purchased failed. The bearing was properly lubricated, and the squirrel cage shaft appeared to be perfectly aligned. It did not appear that the installation was the issue. The bearing's rubber component failed, wadding up and rendering the bearing useless. br>br>When I looked at the other bearing we bought, there was no sign of the same failure. But now I'll have to downgrade to a three-star rating. I've finished using the cooler for the season, so I won't be able to tell if the other bearing is a problem any time soon. But, as I previously stated. . . I don't see why it shouldn't succeed. And I'll just get a new cooler for next year. It had been 23 years since this cooler had been used. This is the first time the original bearings have lasted this long! I wish I had been able to track down some of the original quality.
I should've paid closer attention to the reviews. BUYING THESE IS NOT A GOOD IDEA! THEY ARE TOTAL CRAP. I should have read the reviews more carefully before purchasing these to replace the swamp cooler in our fire station, but I was in a hurry and purchased them anyway. I just finished putting them in. Hmmmm. What's the matter with the "bearings" not turning? What the hell is going on here? Do they have styrofoam pieces attached to them? That's a load of nonsense. Oh. It makes no difference because the inside doesn't turn. In fact, the bearings appear to be fused together and will never turn!

The item arrived quickly and was exactly as described. It went in without a hitch.
I'm very happy with this product; the most difficult part was removing the old one, which had seized and had to be sawed off the shaft. The new one slid right on after that, and the job was completed quickly. br>I haven't used the cooler much, but enough to know that it works well and that the noisy bearing problem is gone. This product comes highly recommended by me to anyone who needs a bearing assembly for their cooler.
It took a while for the parts to reach me, but once they did, they worked perfectly.
