4-bolt flange block spherical roller bearing

[Philrock]

I have a heavy duty application for a 4-bolt flange block spherical roller bearing. The shaft rotates, so secure mounting to the shaft is important. Locking collars at both ends of the bore would be adequate. While looking for a bearing, I found the Moline Bearing M3000 Even-Lok series. Here's a link to the data sheet:

The flange block is a little ways down the page, but all the bearings on the data sheet have the same shaft locking feature.

The design looks like it would do an excellent job of gripping the shaft, if it is well executed. And that is a BIG IF. I would be interested in hearing about anyone's experience, good or bad, with these bearings.

This is basically a friction connection to the shaft. They are very common, and should work just fine if you follow the guidelines provided by Moline. The reason for using a friction connection is to prevent any relative motion between the shaft and inner bearing race bore that would result in fretting damage.

The only thing you must consider when using spherical roller bearings is to make sure the bearing system is not over-constrained axially. You should not use two spherical roller bearings on a single shaft.

Good luck to you.

Thanks Terry,

These bearings come with or out without axial float ability. I'll use one float and one non-float on each shaft.
