How to Install Bearings in a Scooter Wheel

In this guide you will learn how to, without the use of any special tool, install and remove bearings in wheels with a metal core - primarily used for scooters.

If you have tried installing bearings in skate wheels, you have probably also experienced that it is quite an easy process. The bearings are simply pressed in with the fingers and can easily be removed by the use of a regular skate tool. The reason for which it can be that easy, is because wheels for skates are often geared with a plastic core. However, in the case of scooter wheels, the same thing does not apply. Scooter wheels are geared with a metal core which make it harder to install the bearings in the wheel since the metal does not flex at all.

Therefore, when you are to install or remove the bearings in your scooter wheels with metal core, you will be needing some tools. It is possible to get special tools, but it is not a cheap solution, and we therefore show you a way to do it without the use of any special tools. However, we do always recommend that you use professional tools of good quality. If not, you might risk damaging the bearings in the process.

How to install bearings in wheels with a metal core

Tools to use:

• Axle bolt with screw
• 5 extra or old bearings
• Hex key

How to install your bearings:

1. Press the bearings evenly into the core of the wheel using an axle bolt and 5 extra/old bearings. This way, damage to the bearings is minimal.
2. If the bearings go in very tightly, use a metal washer (min. diameter 22 mm) on both sides of the bearings. The washers distribute the pressure better and reduce the risk of damaged bearings.

How to remove bearings from wheels with a metal core

Tool to use:

• Axle bolt
• Hammer

How to remove your bearings:

1. First, position the spacer (located between the bearings) in the middle, so the axle cannot get through.
2. Use your hammer and hit on the axle (which should be placed from side to side) to press the bearings out on the other side.

Note: If you have a self-centered spacer, there is a risk of damaging the bearings when removing them.

In our video, we are using a spacer without flange (not self-centered). This makes it easier to remove the bearing and minimizes the damage to it.

If you are using a self-centered spacer, you have to use a screwdriver and knock on the inner ring of the bearing all the way around it to get it out. This is what can easily destroy the bearings.
