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've tried installing bearings in skate wheels, you likely found it to be a straightforward process. The bearings are simply pressed in with fingers and can be easily removed using a regular skate tool. This ease is due to the plastic core often found in skate wheels. However, the same does not apply to scooter wheels, which have a metal core, making it harder to install the bearings as the metal does not flex at all.
Therefore, when installing or removing bearings in your scooter wheels with a metal core, you will need some tools. Special tools are available, but they are not a cheap solution. We will show you a way to do it without any special tools. However, we always recommend using professional tools of good quality to avoid the risk of 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:
- 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.
- If the bearings fit very tightly, use a metal washer (minimum 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:
- First, position the spacer (located between the bearings) in the middle so the axle cannot pass through.
- Using your hammer, 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 damage to it.
If you are using a self-centered spacer, you will need to use a screwdriver to knock on the inner ring of the bearing all the way around to get it out. This can easily damage the bearings.
