When it comes to roller skating, having the right size bearing is key to a smooth and enjoyable experience.

If your bearings are too small, they will be difficult to turn. If they are too large, they will make skating more difficult and cause excessive wear and tear on your skates.

So, In order to find the right size bearing for your roller skates, you will need to know the size of your wheels and the type of bearing that is compatible with your skates.

How do I know what size bearing to get for my roller skates?

If you want to find out what size bearings you have, there are three easy ways to do it.

1. Look at the stamping on your existing skate bearing shield. The majority of them will be stamped with 608. In other words, you have 8mm. If with a stamp of 627, you have a 7mm bearing.

2. It is also possible to tell by the size of the wheel nut on the wheel. Typically, a 9/32″ nut will indicate a 7mm bearing, and a 5/16″ nut will indicate an 8mm bearing.

3. Take a number 2 pencil using the eraser side of the pencil. Try sliding the bearing onto the pencil. If it is too big to fit through the center it is a 7mm bearing, but if the same pencil slides right through you have a 8mm bearing.

What factors affect skate bearing size

There are a few factors that can affect your roller skate bearing size.

The first is the type of skating you will be doing. Recreational skaters typically don’t need as high quality of bearings as those who race or do tricks.

The second factor is the axle size of your skates. Most recreational skaters have 8mm axles, but some older skates or those with larger wheels use 10mm axles.

If you’re not sure what size your axles are, you can measure them with a ruler.

Finally, the thickness of your wheels will also affect your bearing size. Because thicker wheels tend to need larger bearings to spin properly than thinner wheels.

The different size of bearings used in roller skates

There are many different sizes of bearings used in roller skates. The size of the bearing is important because it determines how fast the roller skate will roll.

A smaller bearing will roll faster than a larger bearing. Because of this, a smaller person will usually use a smaller bearing than a larger person.

Most roller skaters use either 608 or 167 bearings. 608 bearings are the most common size and can be found in most skate shops. 167 bearings are a little bit smaller than 608 bearings and are used by some skaters who want to roll faster.

There are also other sizes of bearings available, but they are not as common as 608 and 167 bearings. Some skaters choose to use these rarer bearings because they believe that they provide a better skating experience.

What to do if you don’t have the right size bearings

There are a few ways to work around not having the right size of roller skate bearings.

One way is to buy new bearings that are the right size.

Another way is to change the wheel on the skate. (The downside to this is that it can be difficult to find wheels in stores that have the same diameter as the ones on your skate.)

A third option is to try and find a bearing that is close in size to the one you need and then use a bearing press to fit it into the skate wheel. (This option can be tricky and might not always work, so it’s best to consult with a roller skating expert before trying it.)
