Product review (3 stars): I actually like this spider...with one exception.
With the aid of a hack saw and a little measuring these bearings were made to fit perfectly. The construction is quite sturdy appearing. I don't know if it will last the 20 plus years of the original spider's, but so far this summer...so good.  I think it could be persuaded to fit most brands of coolers with spider bearings.

Sept. 2, 2014 Update: I do not know what caused the problem...but one Lasco spider bearing, of which I purchased two, failed after part of a months use. The bearing was oiled as specified and the squirrel cage shaft seemed in perfect alignment. The installation did not seem to be the problem. The rubber part of the bearing is what failed, it wadded up and stopped the bearing from functioning.

I inspected the other bearing which we purchased and found no sign of the same failure taking place. But now I will have to change my star rating to a 3. I have wound up the season for using the cooler, so I won't be able to ascertain whether the other bearing would be a problem soon. But, as I said...I have no reason to believe that it would fail. And for next year, I will just pick up a new cooler. This cooler was 23 years old. The original bearings made it this long! I wish I could have found some of the original quality.
