Why Timken is Worth the Upgrade

Bearings and races do a lot of work in a small space, so material quality matters. Timken uses a specialized alloy blend that helps reduce vibration and extend bearing life, with testing showing its bearings and races can last up to twice as long as competing products.It's a higher-end option, but the tradeoff is longer service life and less reason to revisit the same repair.

Video Transcript for Ultimate Overview of the Timken LM603011 Replacement Race

Hi, there. I'm Michael with etrailer.com. Today we're gonna take a quick look at this Timken replacement race. This is a high quality LM603011 race. You can see it does have that industry standard number printed on the side there. So if you're looking for confirmation that this is gonna work in place of the one that you're needing to replace, if you see that number on that original, you can trust this is gonna be a very simple swap out for you.

This is going to work with the bearing models that you see listed on the screen there. This does not come with either of those bearings, but it is gonna be compatible with either of them. So if you are using those already, again, just another confirmation that this will work for you. Our outer diameter is 3.625 inches. So again, make sure that that's gonna work for your setup.

But this is a very high quality race. If you're not familiar, Timken is one of the most well-known and highly trusted brands in the industry, because their products are engineered with higher quality controls, which ensures tighter tolerances and run outs than other manufacturers. That is going to ensure less vibration and noise. It's also going to ensure longer product life, as long as you have it installed properly. And that higher quality is even demonstrated in the way that this comes individually packaged.

with an oil coating on it to help prevent surface rust and that sort of thing. So when you receive it, it's gonna be an excellent condition, ready to be installed. So if you're looking for high quality replacement race, this is gonna be the way to go. And that completes our look for today. Again, I'm Michael with etrailer.com.

Thanks for watching.

Bought some bearings at a local store, and alas, it wasn't a set, glad to see that I could get these separately and finish up my trailer project for the winter!

While replacing bearings and races on my 2006 Triton 190FS trailer, single axle 3500 lbs, I used a CE Smith bearing, race, and seal kit that included an outer race with part number L68111. I could see the bearing numbers on the old equipment but could not find a number stamped on the old race. I spent two hours or more, hammering, heating, and freezing to no avail. The old and new races appeared to be the same size, but the new one just would not go in. Finally, I used a digital micrometer to check the diameter and decided the new one was 1mm larger than the old one. I searched the internet but could find no explanation until I stumbled on the solution in an eTrailer FAQ section which pointed out that the older hubs needed an L68110 inner race. Shipping was fast, price reasonable, and the cooled race went in easily. I'm grateful for the information provided in eTrailer's site.
