Today were going to review part #29031. This is a Redline Grease Seal. This is a single lip grease seal design to be used on a #8 spindle. The overall diameter on this seal is 3 inches. The inner diameter or inside diameter is 1.875. Now also, if you go to the product page for this part number, we will also list a chart.
Its a seal cross-reference chart, and it will list all the different manufacturers that make grease seals and the part number for that manufacturer that will match to this part number. That should do it for review on part #29031. .

Product better than the ones I replaced.
I forgot to order two of these seals and for some reason only
Ordered one.
Need to order another.
Good serviceEverything came in as ordered. Good service . Good parts.
Right part and fast shipping!
I was having a hard time finding a grease seal for an old camper. The website definitely helped me with the info.
Good quality product, fast shipping
a good product for a hard to find item. Installation was a breeze.
Proper fit. Put them through 11 hours of use during the second day.
The serves you have given is out standing, couldn't any better.
I can only comment on one thing.. I was looking for the delivery by the (UPS)
as your Emails had suggested.. The items was sent by (USPS) this is no
problem. I thought UPS had screwed up like several weeks ago.
Now I don't have time to install them bearing right now as I'm cutting
fire wood, but as soon as I can get them installed I'll respond again.
Thanks George..
Best Regards..

George,
I ended up at etrailer after a fairly exhaustive search for all of the hard parts contained in my order. I found Timken bearings, but not all of them. I found SKF seals but they were 4 days out plus for delivery. The cost of USA made name brand bearings wasn't the issue for me, it was availability.
As you may know, the axle that takes those 3" OD inner bearings with such a small 1 1/2 spindle is an old, possibly very old Ag or boat trailer axle. They are meant for high load, but slow speed use. In comparison, the bearings you sent while appearing to be of good quality to the naked eye are also much smaller rollers indicating a higher speed bearing but of less maximum load capacity. None of this really matters when you have such a hard time finding the parts needed to complete the job in question. I simply state this for your information, but certainly, you were already aware if the differences in sizing and load capacity. It's doubtful that the trailer in question will EVER see enough load to make any difference in performance whatsoever, so please don't take my statement as a complaint.
As for the seals, they are the correct dimensions, and I did find your website helpful in double checking my cross reference work between brands. I'm also sure they will work just fine, but they do lack an innerspring to hold the tension of the inner lip seal against the spindle's seal area. Again, they will do the job, at least at first but I'd guess they won't last nearly as long and aren't a double lip seal design as the SKF, and National brands were. I'm not complaining one bit here, I promise. The cost factor differences were dramatic to say the least. The 2 inner bearings and 2 inner races made by Timken were equal to ALL 4 bearings and races, plus the seals from you guys.
Look, I realize that stocking such expensive and nearly obsolete parts made in the USA isn't a business model for anyone who wants to stay in business very long selling something that can be found down the street at nearly the same price. I understood what I was ordering before I ever started putting things into the cart on your website.
As a heavy equipment mechanic of 30 years experience, I promise your parts will get the best of treatment and a proper start to their life, hopefully, a long use life without issues. The bearings will be sonic cleaned before they are every packed with the best of grease choices. All the races and the seals will be installed with the proper driver to make sure they are square and seated correctly into the hub bore.
I assume if you use this review of mine for your website that you will not edit it in any way. What people using your site and customer service need to understand is that while I might see the differences I do not think I purchased ANY sub-par parts. Other customers need to also know that "In Stock" with you guys means "In Stock" and after hours of phone calls looking for those particular parts it was a very welcome thing to read on a website and even better when the order shipped On Time, Complete, and at what I consider to be a very reasonable cost. They would also need to know that your website is just chocked full of easy to find information. My example besides the seal cross reference information is the wiring diagrams. The color differences between RV trailers and Utility trailers makes you double check things to make sure you got it right and ALL that info is readily available on your site. Much easier to access than other companies.
In closing to what certainly is an overly detailed reply to your request for feedback, I'd just like to thank you, George. Thank you and your company for doing the EXACT thing you said you would and thank you for taking away a fair amount of frustration searching for parts. I will certainly use your company again and again if for nothing else, it's ease of use and promptness of service.
If you'd seriously like pictures I will be happy to try and supply them at a later date. For now, this old trailer has to get back to earning its way.
etrailer had this hard to find part in stock. Delivery was as stated. My salesperson McCoy was helpful and knowledgeable. All the components were in one box ant individually wrapped, but fortunately no damage seen. Now the work putting everything back together begins.
The young lady who helped me over the phone was outstanding. My old grease seal was by a manufacturer that was long, long gone. The part number did not translate into anything current. She helped me figure out which seal was most likely the right one for me. She was right on. Fit perfectly.
These seals arrived on time and in good shape, although the package was torn open and I feared some kind of vandalism or theft. But both seals were contained in a small zip lock baggy inside the envelope. They are the correct size and just what I needed. Appreciate the speedy service and fair price. I will need two more next week and will place the order then. I wanted to sure these were the right size. They are. Thanks.
Exact replacement.

No problems, everything is in good working order.
I had purchased a trailer with Trostel 300-156-6F seals and couldn't find anything at local stores for replacement. I took to the internet and found etrailer and the recommendation for these replacement seals. I ordered the seals, and they were quickly shipped and arrived at my house in a timely fashion. Replaced the old seals and worked perfect!
Looks good, should work well.
Great price, fast shipping, All in stock parts, great service.. Thanks from the great White North

great
It was an really good fit. I sent you some pictures already,did you get them?
Disappointed in the packaging! 4 bearings, 4 races & 2 grease seals just thrown loosely into a envelope mailer! They just banged around for a week in the hands of the shipper! How can you just throw these kind of parts loose without individually wrapping them in bubble wrap? Horrible service!
This seal did not fit my hub. The original seal was a National 203034 seal. The outside and inside diameter were the same but the rubber contact area was offset
by about 1/4 inch and would not grip my hub. The national seal was a centerline seal without any offset. If my seal area on my hub was longer then this seal would of have worked.

Thanks for the feedback Randy. But the National Seal cross reference for this seal is 440298. So that would likely be why this is not a direct match for you. I did look and at this time we do not carry a seal with this as a cross reference.
Searched everywhere for these seals and these were exactly what I needed. Thanks!
great customer service, fair price and fast shipping.. super happy with overall service

Excellent, couldnt be happier that their are good companies providing great services and good quality products Thank you again
Awesome service
Item was exactly as described. Shipping was fast
This size seal has been hard to find as it is on an older trailer with older axles. These were perfect and fit as expected and seemed to have a great seal on the axle. eTrailer again was great to work with as communications is the key thing they have always had. Thanks again and will be back again.

After some explaining to the owner of the trailer that none of these bearings were intended for high speed highway miles at least not many hes taken it easy on this ancient trailer. So far, everything works very well, with no grease leaking past seals and all the bearings carrying their weight well.
