Bearing Buddy Size Guide: The Importance of Choosing the Right Fit for Your Trailer

Ensuring the optimal performance and longevity of your trailer's wheel bearings is crucial for a safe and reliable towing experience. The selection of the correct bearing buddy sizes is a critical aspect of this maintenance process. Read on to discover how choosing the right size can prevent costly repairs and maximize your trailer's efficiency.

Benefits of Using Bearing Buddies

Increased Bearing Life: Bearing buddies act as seals, preventing contamination and moisture from entering the bearing assembly. This significantly extends the lifespan of bearings, reducing the frequency of replacements and maintenance intervals.

Reduced Friction and Heat: The presence of bearing buddies creates a barrier between the bearing and the grease, minimizing friction and heat buildup. This reduces wear and tear on the bearings and prevents premature failure.

How to Determine Bearing Buddy Sizes

Step 1: Measure the Bearing Outer Diameter: Determine the Outer Diameter (OD) of the trailer's wheel bearing. This can be found in the bearing's specifications or measured using a caliper.

Step 2: Consult the Bearing Buddy Size Chart: Refer to the bearing buddy manufacturer's size chart. Find the model that aligns with the bearing OD and choose the corresponding bearing buddy size.

Bearing Outer Diameter (OD)	Bearing Buddy Size
1.750" - 2.000"	BB800
2.001" - 2.250"	BB2200
2.251" - 2.500"	BB2500

Step 3: Confirm with Manufacturer: If unsure, contact the bearing buddy manufacturer for guidance in selecting the appropriate size.

Stories of Bearing Buddy Success

Story 1: Increased Bearing Life

"I regularly tow a heavy load with my trailer. After installing bearing buddies, I've noticed a significant increase in the life of my wheel bearings. I've saved a lot of money on replacements and downtime." - John, a professional hauler

Story 2: Reduced Maintenance Intervals

"My trailer used to require frequent bearing repacking. After using bearing buddies, I can extend the repacking intervals to twice the recommended period. This saves me time and effort." - Susan, an avid camper
