Hello, hoping someone can help answer a question about replacing the pillow block bearings on an old HP polisher/grinder machine I'm repairing. Please keep in mind, I am new to this. I would like to replace the bearings, but I'm having trouble identifying a proper replacement. Below is a link to the original ones, which fit a 1" arbor and have about 3 3/8 spacing between the mounting holes. I do not see a way to replace just the inserts, as they aren't built like the ones I've seen online that can be turned and pulled out. Also, the inserts I have found cost more than new bearings, presumably. Sealmaster SRC-16 i350.photobucket.com/albums/q406/allanrocky/20170518_180735_zpsd5akznjb.jpgWould the following be a suitable replacement? It took quite a bit of time to finally find one that had the same distance between mounting holes. I measured the distance between the actual holes, but don't know what measurement bearing manufacturers use (this, or center of hole to center of hole, or outside of hole to outside of hole). 1" Pressed Steel Pillow Block Bearing SBSP205-16 www.thebigbearingstore.com/1-pressed-steel-pillow-block-bearing-sbsp205-16/Any help you someone can provide would be very appreciated!

I guess the holes are important.
My 1" shaft diameter AMI pillow blocks are 4-1/4" center to center.

If Big Bearing units are listed as replacements for original bearings go for it. May not last 40 years like the original but cheap enough to replace if needed. Lapidary equipment doesn't generally run non stop so no need to break the bank. The old HP equipment I have worked on had the standard pillow block bearings like Shotgunner mentioned. Hole sizes are center to center. Ball bearings always better than sleeve if you have a choice.
