Abec 9

Bearings are a fundamental component of the skate and guarantee (if correctly maintained) an optimal level of roll for the wheels.
The bearings ABEC 9 are designed for high performance and represent the best option for this discipline.

  • The minimal level of radial movement evenly distributes the load on the spheres to guarantee an excellent level of smoothness.
  • Suitable for all frames with 7 mm axles
  • Steel casing with a 7-ball cage, immersed in carbon to provide additional self-lubrication
  • Single-sided hermetic removable rubber protection to facilitate cleaning and lubrication operations.
  • Provided in sets of 16 (It is at the discretion of each reseller to sell units in smaller quantities).
Roll-Line does not sell directly to the public; to complete your purchase, please refer to an official reseller.

It is advised to verify the condition of your equipment at every use.
In particular, it is advised to check:

  • the correct roll of the bearings, which must be fluid and free of noise
  • the secure closure of the lock nuts on the wheels


It is advised to periodically clean the bearings, being mindful to:

  • Remove the bearings from the wheels using the correct bearing press
  • use the products specified from the Roll Line© lineup for cleaning and lubrication*
  • avoid harsh products such as alcohols, gasoline, etc.


*These products may not be available in some countries or regions

If used extensively (for frequent training and competition), it is advised to replace the bearings every 6 months to guarantee the optimal performance of the equipment.
Regular cleaning and lubrication contributes to a better lifespan of the product.

It is recommended to always have a spare set of bearings to use in the approach to, or during competition to increase the velocity of the skating.

For more information on how to clean the bearings, please see the tutorial video.

The spacers (available as an accessory with code STD192) are strongly recommended for multiple reasons:

  • assist in positioning the bearings in a parallel positioning
  • optimize the performance of the bearings, increasing the roll
  • the axle of the truck is reinforced, reducing the risk of bending or breaking
