PGN UCP204-12 Pillow Block Bearing - Pack of 2 Mounted Pillow Block Bearings - Chrome Steel Bearings with 3/4 Bore - Self Alignment

While they seem well built, they are apparently 19 mm (.748) . As I was supporting the shaft on the ends, I was able to turn the excess off the shaft to accommodate the bearings. Once that was done, they suited my purpose very well, but you wont be able to put a true 3/4 inch shaft into these.

Dont know how they can produce something so robust, yet so inexpensive

Used in a swamp cooler. Much quiter now. Good product.

Its been running nonstop on my tumbling machine I built for a week and works great. I like having the grease fittings.

Good bearings for small projects. I would steer away from using these industrially. The cast pillow block is hallow on the bottom where the bolts go through, you can break these by just tightening the mounting bolts hard enough

Sturdy product

it took two sets to make one so far is working time will tell

Works great

It worked good

These are a great product, and priced well
