Bearing Buddy3000.091 42102 Chrome Bearing Protector - 1.980" Diameter, Pair

Can't wait to try them

The bearing buddy is supposed to keep the grease under slight pressure for the wheel bearings. The product looks fine but is exposed itself with no caps supplied, nothing to tell you they are not included or where to get them.

Perfect fit on my boat trailer hubs work awesome.

Otherwise, they work great. This model doesn't have the relief hole in the side that tell you when it is full enough. The small downside is that you have to watch the piston to see when it starts to compress the spring. The huge upside is that you don't have grease oozing out the hole - getting on the wheel, and gunking up the bra (optional cover). Actually, I used these along with the inner bearing stainless steel seal conversion kit Bearing Buddy sells as well. For that, these are a must to apply positive grease pressure to the inner seal. If you are dunking your wheels in water, either puddles, lots of rain, or on a boat trailer - these along with the inner seal conversion kit are a must. NO MORE grease leaking and messing up the back side of your wheels - and NO bearing failure - ever!

Bought this for my boat trailer and they worked great! Make sure to pack with grease to keep water out.

This product is officially amazeballs. I had some trepidation on buying these as I wasn't 100% certain that they would fit my application, especially with the claim "If your outer bearing race is just under 2", this is the correct fitment for your trailer." Except, that is exactly correct. These fit perfectly, the instructions on use were easy to read and understand, and during installation, everything worked exactly as advertised. I will recommend these to anyone, whether or not they have a trailer!

Great product! Been using them for 6 years. Follow the directions - do not over fill/pump. As pressure/heat builds during long travel you may get a little grease leaking - Keep the cover cap on to catch any grease. remove cover cap once in awhile and let the inner grease nipple area dry - clean the dust out. Great product! The pressure 24/7 will keep water out of your bearings! This is good!
