The Ultimate Guide to Trailer Wheel Bearing Size Charts
The Ultimate Guide to Trailer Wheel Bearing Size Charts
Step 1: Determine Your Trailer's Weight and Axle Type
- Trailer weight is crucial in determining the required trailer wheel bearing size chart.
- Single-axle trailers typically have a load capacity of 3,500-5,000 pounds, while tandem-axle trailers can handle 7,000-10,000 pounds.
| Trailer Weight (lbs) | Axle Type | Bearing Size |
|---|---|---|
| 3,500-5,000 | Single | 1.5" ID x 2.5" OD x 0.5" W |
| 7,000-10,000 | Tandem | 1.75" ID x 3.0" OD x 0.5" W |
Step 2: Inspect the Existing Bearings
- Inspect the bearings for any signs of wear or damage.
- Replace the bearings if they show any signs of pitting, rust, or excessive play.
- The trailer wheel bearing size chart will ensure you purchase the correct replacement bearings.
| Bearing Type | Inner Diameter (ID) | Outer Diameter (OD) | Width (W) |
|---|---|---|---|
| Tapered Roller Bearings | 1.5" | 2.5" | 0.5" |
| Ball Bearings | 1.75" | 3.0" | 0.5" |
| Needle Bearings | 1.75" | 3.0" | 0.5" |
