Understanding Trailer Wheel Bearings Sizes for Optimal Performance
The Importance of Proper Sizing
Trailer wheel bearings play a crucial role in the safe and smooth operation of your trailer. Ensuring that the bearings are the correct size is essential for maximizing performance and minimizing the risk of failures.
Sizes and Capacities
Trailer wheel bearings come in a range of sizes to accommodate different trailer weights and applications. The most common sizes are:
| Bearing Size | Inside Diameter (ID) | Outside Diameter (OD) | Width |
|---|---|---|---|
| L44649 | 1.0625" | 1.9375" | 0.5625" |
| L44610 | 1.1875" | 2.1875" | 0.6250" |
| L68149 | 1.3125" | 2.4375" | 0.7500" |
The bearing size you need will depend on the weight rating of your trailer. Generally, heavier trailers require larger bearings.
Capacities
Each bearing size has a specific weight capacity:
| Bearing Size | Capacity (lbs) |
|---|---|
| L44649 | 1,650 |
| L44610 | 2,200 |
| L68149 | 2,800 |
Choosing bearings with the proper capacity is essential to prevent overloading and premature failure.
Success Stories
