Measuring a bearing for a bike

Measuring a bearing is a simple task when done correctly using a vernier caliper.

We start by measuring the bore of the bearing, known as the inside diameter or ID. We do this by placing the small jaws of the vernier in between the ID; using the slider to open them up and get a reading on the scale.

Next, we use the large jaws and place them around the outer circumference of the bearing, known as the outside diameter (OD), again, opening up the slider and closing it around the OD to get a measurement.

Finally, we measure the bearing width (W) using the same technique as the OD.
