How to Install Bearings in a Scooter Wheel

This guide will teach you how to install and remove bearings in wheels with a metal core, primarily used for scooters, without the use of any special tools.

If you have tried installing bearings in skate wheels, you have likely noticed it is quite an easy process. The bearings are simply pressed in with the fingers and can be easily removed using a regular skate tool. This ease is due to skate wheels often having a plastic core. However, the same does not apply to scooter wheels, which have a metal core. The metal core makes it harder to install the bearings because it does not flex.

Therefore, when installing or removing bearings in your scooter wheels with a metal core, you will need some tools. While special tools are available, they are not a cheap solution. Hence, we show you a way to do it without special tools. Nevertheless, we always recommend using professional tools of good quality to avoid damaging the bearings.

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

Tools 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 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 use a spacer without a 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 must use a screwdriver to knock on the inner ring of the bearing all the way around to get it out. This can easily destroy the bearings.
