Check grease levels at a glance with the blue auto-check ring. Chrome plated Bearing Buddies maintain light grease pressure inside the hub to protect your bearings, even when submerged, while the zerk fitting makes adding grease quick and easy.
Features:
Specs:
Replace your existing grease cap with a Bearing Buddy for an easy way to monitor and maintain the grease level in your axle hub. Use a grease gun to add grease through the zerk fitting. As the hub fills, the spring-loaded piston moves outward, raising the blue auto-check ring. When the blue ring is 1/8" above the steel retaining ring, the hub is properly filled.
The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The pressurized grease inside the hub helps prevent water from entering and contaminating the grease. Bearing Buddy also includes an automatic pressure-relief feature to help prevent overfilling and damage to the inner seal. Once the hub is full, excess grease seeps around the edges of the piston and into the barrel while the blue auto-check ring remains raised.
Check the blue auto-check ring to see when it's time to add grease. If the ring has receded below or is flush with the steel retaining ring, more grease is needed. If the lip of the blue ring is 1/8" above the steel retaining ring, the hub is properly filled.

Hello Neighbors, it's Brad here from etrailer, and today, I'm at NATM. And this convention brings a lot of the vendors that we have at Etrailer to a convention where we have their booths and their products set up. I had a chance to catch up with quite a few of them. So let's take a look at their products a little bit up close and ask some of the questions to those vendors about their products. I'm here with Wandalinn from Bearing Buddy and Bearing Buddy is a brand that we carry here at Etrailer. I've heard the name, people swear by them.
And what is Bearing Buddy Okay, Bearing Buddy is a wheel bearing protector for any kind of trailers like boat, utility, and RV trailers. The purpose of the product is to protect the bearings and all the spindle and keep it lubricated because when you go to the road on the outside, you're gonna protect it against mud, water, salt, okay And as you can see, you can add the grease up here through the zerk fitting. And it's pistol-loaded and it has a spring that's gonna create a force or pressure outside the Bearing Buddy, so the grease is not coming out, but the water is not gonna come in, okay And you will keep the bearings in good conditions. How do you know if you add the correct amount of grease Okay, this is very simple. You're gonna add the grease in, the lubricant indicator's gonna come out, okay 1/8 of an inch, and it's gonna tell you that you have enough grease.
Our product stems from the other ones because we have a good quality, the internal components are made of stainless steel, okay For example, this spring push and keeps the differential first of the three PFA. A very common point question that we've received from customers is if we add too much grit, those seals are gonna blow out. I wanna tell you no, they're not gonna blow out, why Because the spring is gonna push three PSI, and the seal resists 10 PSI, okay And if you add too much grease on it, the breeze is gonna come out from the sides, okay And they won't blow those seals, okay We also have the Bearing Buddy Bra that keeps the grease out of the wheels, okay You can put it on the top of the Bearing Buddy, and there will be a clean system on your tray. How often do you recommend repacking bearings If you have the Bearing Buddies, we don't recommend you to pack it, okay But customer needs to know that you need to give a good maintenance to the wheel. Your wheels need to be balanced, good condition.
Then the wheels cannot be wobbling because then the Bearing Buddy is gonna come out or everything that you have inside it, it can be damaged. Really cool design. And really, who is this for Who would want this Everybody that has a trailer, okay And we love farmers. Every time they come with a good question or a special need, we made a custom made Bearing Buddy for them, okay And utility trailers where they use the trailer for work, okay And they want the investment to be, how do you say it You want to make sure your investment is safe, okay And you need a trailer without good condition. And we at Bearing Buddy assure you that you're gonna have that.
And that's something with a work trailer, yeah, you're wanting to use that for work, and having a trailer that's not operating properly makes it where you can't work. And this is something. Maintenance I've done on all my cars, but if there's something that I can put in place to avoid having to do maintenance long-term and protect it, I think that's a win. So very cool product. Okay, thank you. Thank you. Nice meeting you. Nice meeting you.

Just started our camping season. Pulled the caps off, hooked up the grease gun, pumped some grease and done. Took longer to write this then grease. No pulling the 4 tires to get to the bearings and getting my hands greasy.

Working great! Check the bearing buddy before and after using trailer and keep them filled. Couldnt be happier with my results. I feel confident I wont have any bearing failure for lack of grease!
