speed max

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

The Speed Max are the only bearings equipped with 8 balls/spheres rather than 7
This, coupled with the minimal level of radial movement which evenly distributes the load on the spheres, guarantees an unparalleled level of smoothness and roll
Suitable for all frames with 7 mm axles
Reinforced steel casing with an 8-ball cage, immersed in carbon to provide additional self-lubrication.
Hermetic single-sided protection to prevent dust infiltration.
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.

Control and maintenance

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 specific products of the Roll-Line© range for the cleaning and the lubrication*
avoid harsh products such as alcohols, gasoline, etc.

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

Periodic replacement

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.

FURTHER RECOMMENDATIONS
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.

Use of spacers

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
