PGN UCP204-12 Pillow Block Bearing - Pack of 4 Mounted Pillow Block Bearings - Chrome Steel Bearings with 3/4" Bore - Self Alignment

These are excellent for replacing swamp cooler sleeve pillow bearings. You may have to drill new holes depending on your cooler, but it's well worth it. Grease fittings make seasonal maintenance easy.

work well

Used as part of my attic lift. MUCH heaver than I needed but couldn't beat the price. I will never approach even 25% of their capacity. I like pillow bearings as they are 'self aligning' [don't have to have each bearing EXACTLY on the same axis] ONLY con, they were about .0015" UNDER size, had to lap the shaft a bit to get it to fit.Would recommend for anyone building a lift requiring bearing supports.

Excellent bearing and price. Nice the stop collars were included too.

The media could not be loaded. I got these a to replace the cheap pillow bearings that wear out every other year on my swamp/evaporative cooler. They were wide enough to fit on the rail in my mastercool (1.5" wide), and a drill bit away from having new bolt holes. It made the squirrel cage about 1/4" higher, but no issues with airflow from that. My cooler only spins at a max of 2100rpms which is far below the max these are rated at.All that I added were the M10 bolts and nylock nuts. I'll update this review over time and if anything changes.For my cooler upgrade application:Pros:- 2 grub set screws per bearing- Pre aligned bores- grease zerk with protective caps (will see how long those last)- Sealed pillow bearings on each side so the grease doesn't just fling out- Nicely machined 1" bore- Pre greasedCons:- No additional hardwareOther:- Because I was using these in a very different application, not surprised bolt holes didn't line up with old cheap swamp cooler pillow bearings. So this means you'll need to drill some holes in your rail to make it fit with proper bolts.

Worked good thanks

Looks good

I purchased a two pack of these pillow block bearings for a flat sander project that I had just finish designing and I am now in the process of building. I am always amazed at these bearings and how well they work and how cost-effective they are I have mounted up my large 22" long contact Drum between two of these bearings and they run smooth as silk. The bearings seem to be very well built and are double sealed and should hold up well in this application I have used similar bearings from this company before and they have lasted a long time. I highly recommend these bearings and would use them again. Thank you
