Question:

Hi, Im looking for a bearing protector for a Mastercraft trailer for a 2003 X10 boat. Its a single axle trailer with 6 lug nuts per wheel. The old bearing protector had Reliable written on it and was made out of plastic. It screws in and the diameter of the threaded part is 2.5 in. The trailer model and serial number is SA-05-MS210, B9-000045.

While I unfortunately could not find any specs on your Mastercraft trailer with serial numbers SA-05-MS210 and B9-000045, there is a definitive way you can measure your trailer to get the correct bearing protector size you need.

In order to determine your size, you need to confirm the diameter of your hub's bore opening. This size determines what bearing protectors you need. For instance, if you find that your bore is 2.441" in diameter, you would need the Bearing Buddy Bearing Protectors - Model 2441T-SS # BB2441T-SS. Since the measurement needs to be precise, I recommend using calipers like the # PTW80157 to make your hub bore measurement.
