sourcing map 30205 Single Row 25mm x 52mm x 16.25mm Taper Tapered Roller Bearing

Bearing was a install and go situation

Taladro

I purchased four of these for a Harbor Freight 4' x 8' folding trailer with 4 lug hubs. Once I got the old bearing off and cleaned the shaft and hub, these new bearing went on pretty easily. I had to use my shop press to install the outer race into the hub, but you could probably us a bench vice and/or a hammer. The inner race of the inner bearing had to be hammered into place.For those who have never replaced a bearing before...If you are getting these for your Harbor Freight trailer, remember that there are two bearing per wheel. If you are replacing the bearings, you might as well replace the seal. Also make sure to grease them and look on YouTube if you don't know how. Be very careful not to scratch the surface of the outer race, it could lead to premature failure.The tools I used to remove old and install the new bearing were:- Bearing Pulled- Hammer / Mallet- Large Flat Blade Screw drive- Shop Press (could use hammer or bench vice)- Grease Gun- Angle Grinder and/or Dremel tool (if you need to cut the bearings off the shaft or hub)- Socket Wrench- Floor Jack and Jack Stands

Perfect for my project

trailer bearing.I got it with one day shipping from 100 miles away which is pretty amazing.. standard bearing quality no better no worse than any other bearing.
