How to Take Bearings Out of Rollerblade Wheels

Published in Rollerblade Maintenance 4 mins read

Taking bearings out of rollerblade wheels is a routine maintenance task essential for cleaning, replacing, or upgrading your skate bearings. This process, as demonstrated in various resources like the "Pit Stop - Take out your inline skate bearings" video (which covers removal and replacement between 0:11 and 2:43), is straightforward and can be done with basic tools.

Essential Tools for Bearing Removal

Before you begin, gather the following tools to ensure a smooth bearing removal process:

  • Skate Tool or Allen Key: Most rollerblades use an Allen key (usually 4mm or 5mm) to remove the wheel axles. A multi-purpose skate tool often includes this.
  • The Axle Itself: The axle that holds the wheel is typically used as a lever to pry out the bearings.
  • Clean Cloth: For wiping off dirt and debris.
  • Optional: Bearing Press/Puller: While not strictly necessary for this method, a dedicated bearing press or puller can make the job quicker and minimize stress on the bearings.

Step-by-Step Guide to Removing Bearings

Follow these steps to safely and effectively remove bearings from your rollerblade wheels:

  1. Remove the Wheel from the Frame:

    • Using your skate tool or Allen key, unscrew the axle bolt that secures the wheel to the skate frame.
    • Once the bolt is loose, pull the axle out completely and carefully remove the wheel from the frame. Set aside any spacers or washers that might be on the axle.
  2. Position the Axle for Leverage:

    • Hold the wheel firmly in one hand.
    • Take the axle you just removed and insert its threaded end (or the non-hex end) into the center hole of one of the bearings, only about halfway. Do not push it all the way through, as you need the edge of the axle to catch the inner ring of the bearing.
  3. Leverage the First Bearing Out:

    • With the axle partially inserted, tilt the wheel slightly. Use the axle as a lever, gently prying the bearing outwards. You should feel the bearing begin to pop out of its seat in the wheel core.
    • Once one side of the bearing is out, you can usually pull it the rest of the way by hand.
    • Be careful not to apply excessive force, as this can damage the bearing or the wheel hub.
  4. Remove the Spacer (if applicable):

    • After the first bearing is removed, you will usually find a small metal or plastic spacer inside the wheel core, located between the two bearings. Remove this spacer and set it aside; it is crucial for proper wheel rotation.
  5. Remove the Second Bearing:

    • Flip the wheel over.
    • Repeat the process from step 2 and 3: insert the axle partially into the remaining bearing and leverage it out.

Tips for a Smooth Bearing Removal

  • Cleanliness is Key: Before starting, wipe down your wheels and axles. Dirt and grime can make removal more difficult and potentially damage components.
  • Gentle Force: Bearings are designed to fit snugly. Apply steady, gentle pressure rather than sudden, strong force. If a bearing seems stuck, try rotating the axle slightly while applying pressure.
  • Check for Seized Bearings: If a bearing is severely rusted or seized, it might be harder to remove. In such cases, a little penetrating oil applied to the bearing's outer race might help, but ensure you clean it thoroughly before reinstallation.
  • Keep Parts Organized: As you remove bearings and spacers, keep them together with their respective wheels to avoid mixing parts, especially if you're working on multiple wheels.

Why Remove Bearings?

Bearings are removed primarily for maintenance purposes, which includes:

  • Cleaning: To remove dirt, dust, and old lubricant that hinder performance.
  • Lubrication: To apply fresh grease or speed oil.
  • Replacement: When bearings are worn out, rusted, or damaged.
  • Upgrading: To install higher-quality bearings for improved speed and durability.

By following these steps, you can effectively take bearings out of your rollerblade wheels, preparing them for maintenance or replacement, and ensuring your skates remain in top condition.
