Expert Answers about Bearing Buddy

  • What is the Bearing Buddies Bearing Protectors Purpose
  • The Bearing Buddies are designed to protect your bearings by keeping water and dirt out of the hubs and bearings and ensuring there is enough grease inside the hub. If you are not experiencing any problems or visually see any grease leaking out of the hub, then you shouldn't have to repack your bearings regularly. I recommend checking your hubs once a year to inspect the condition of your brakes. If you notice any grease leaking out of the hub, then grease could have been compromised,...

  • Grease Cap for a Concrete Mixer with Inner Diameter of 2.375
  • The closest grease cap we offer to the dimension you listed that is designed for a trailer hub would be the # F001601, this is designed for a 2.333 inner diameter hub so it might be a little small. It is a press on style that does not have a rubber seal though. Since this is designed for trailer hubs I can't safely guarantee that it would work for you.

  • Are Grease Seals Supposed to be Curved to Match the Radiused Edge of Bearings
  • Every bearing we sell has that radiused edge that you are referring to so all of the seals we carry would work as long as you get the correct one for your setup. Grease seals do not seal the bearing so they do not have to match curvature. The seals seal the hub bore. Can you tell me what the bearing number is on your bearing? There's a glare in the picture so I can't see what bearing you have to match the correct seal to it. I attached a link to an FAQ article on wheel bearing backing...

  • What is the Outer Diameter and Thread Pitch of Bearing Buddies # BB2441T-SS
  • I went out to the warehouse and pulled Bearing Buddies # BB2441T-SS. The outer diameter of the threaded portion is 2.34 inches using digital calipers to measure. The thread pitch is harder to determine. There are approximately 9 threads per inch (only three threads on the actual product) and it is coarse threaded as opposed to fine threaded. These Bearing Buddies are designed to replace Tie Down Turbo Lube oil baths.

  • Which Bearing Buddy and Grease for 1700 Lbs Carry-on Utility Trailer
  • Although bearing buddies are primarily meant for boat or PWC trailers, you can certainly use them on a utility trailer.

You will want to match that measurement as closely as possible to the measurement on the Bearing Buddy product pages. I have attached a link to all of our bearing protectors for you to reference.

  • How to Remove a Bearing Protector from a Trailer Hub
  • Bearing protectors like Bearing Buddies are a very tight fit in a hub. If you cannot wiggle it out by hand then using a rubber mallet and tapping it (not hard but firm) first on the left, then the right, then the top, then the bottom, then repeat, will help loosen it up so you can pull it off. I have included a link to a video as well that should help. Removal of the Bearing Buddy takes place right in the beginning of the video.

  • Troubleshooting Disc Brake Calipers that Don't Line Up with Rotors After Seal Saver Install
  • First thing you want to do is verify that you have installed the Bearing Buddy Seal Saver kit part # BB60010 that you referenced like the video I attached demonstrates. When properly installed the seal saver kit would not push the hub out any further preventing the brake mounting flange from installing properly. What I suspect is happening if the Seal Saver is installed properly is that you need to compress the pistons of the caliper more to allow it to slip over the rotor. Using a c-clamp...

  • Finding The Right Size Bearing Buddy For Utility Trailer
  • You'll need to use an accurate measuring device like a digital caliper to measure the inside diameter of the hub bore. A ruler or tape measure wouldn't be accurate enough.

  • How to Measure to Determine the Correct Grease Seal on a Trailer Hub
  • I could not find any information on the seal number you listed so yes, you will need to take an accurate measurement of the outside diameter of your existing seal, or the inside diameter of the mounting surface for the seal in the hub. You will also need an accurate measurement of the spindle at the seal surface. I have posted a photo to show the dimensions you will need to measure. A dial caliper will provide an accurate measurement to determine the correct seal for your hub and spindle. I...

  • Bearing Buddy Grease Seal Recommendation for L44649
  • The inner diameter of the steel ring of the # BB60008 is 1.25 inches as it is designed to be used with hubs that have an inner bearing number of # LM67048. Since your inner bearing seems to have a 1.5 inch inner diameter most likely you have the L44649 bearing (you need to verify this), and the correct kit for you would be part # BB60005.
