Convert your threaded oil-bath hub to grease with stainless steel Bearing Buddies. It 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:
This threaded Bearing Buddy lets you convert an oil-bath hub to grease lubrication while giving you an easy way to monitor and maintain the grease level in your axle hub. Bearing Buddy recommends using grease-proof gasket cement during installation. To add grease, use a grease gun through the zerk fitting. Adding grease moves the spring-loaded piston outward 1/8".
The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The Bearing Buddy maintains slight pressure inside the hub, helping prevent water from entering and contaminating the grease. An automatic pressure-relief feature is built into the Bearing Buddy. When the device is full, grease will seep around the edges of the piston and into the barrel. This helps prevent overfilling that can damage the inner seal.
You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

I purchased the 2080T-SS bearing protectors which the Bearing Buddy people tell me is the correct size for my hubs. Havent installed them as yet as I had to refill the hubs with oil when I received the wrong size Bearing Buddys. Ill probably do the oil to grease conversion this Fall, or next Spring.

Thanks for sharing that, and I’m sorry these didn’t end up being the right fit for your setup. You’re exactly right, oil bath hubs often require a different size or style, and matching that inner diameter is key. It sounds like your hubs are set up for the 2080 size, which would explain why these didn’t work. If you’d like, we can help confirm the correct size for your hubs so you’re not guessing on the next set. If you have a hub model number or can measure the bore, we can make sure you get the right fit the first time

Yes the cap work OK guess I made one trip with them. It was from my home at Gulf Breeze Tiger Point, FL back to Sulphur Rock, Indepentence Co, AR which is about little over 600 miles one way and they did really great.
