RedRider, I am a Master Mechanic (Electician, Machinist and Mechanic) in well known spice packaging plant. And since I am a mechanic and you are an Engineer we are sworn rivals:). I went to work today and got out the TIMKEN PRODUCT CATALOG I use to reference bearings:detective:, and found this page below. This is the information I had in mind when I made my post about a THROUGH hardedned part I admit this information has very little to do with my original post, I hope you take this banter as good natured fun. I would bet as a Bearing Engineer you have forgotten way more about bearings than I will ever know:bowdown: http://i78.photobucket.com/albums/j109/essixx/TIMKIN_zps7cff9877.jpg

Thanks for the info:)

Not sure what you mean by both the inner & outer race. The Amaazon Bearing I have, which is RBI manufacture labeled, is the outer race and tapered roller bearing ready to be greased and put in your hub and onto your axel. I do see the Bearings they have now are "VXB" branded, so I see you don't always know what you will get. You are correct,my bearing is made in China. Thank you for pointing out an alternative. TIMKEN is a quality part. I believe the M designation means "Through hardened steel" instead of "case hardened steel" but I could be wrong. The dust cap had me going for a while. Had to use my calipers and then google it.

Hi All, Want to contibute and put information that I had to dig for, in one place for everyone. The Harbor Freight Tag-a-long trailer uses a grease seal that is 30x52x10mm. Amazon has them. They call it an "Engine Oil seal. I just packed my bearings and this looks to be the exact seal HF uses. Redtrailers.com has them too and part# is SJ8510-18B. They also have the complete hub assembly with pre-greased bearings as part# SJ8510-18-30205B. Amazon also has the bearings with race with the bearing # being 30205. Original Dust cap is carried by Harbor Freight as Item #93833. This is an odd sized dust cap and is not carried by some places. It measures at 2.06" So those that would like to use A Bearing Buddy would use #2047. I hope this helps someone.
