Spacer Definitions

Positioned between the bearings within each wheel, spacers are utilised in skates, scooters, waveboards, and virtually any device that moves with bearings.

It's crucial to select appropriate spacers for your wheels. Omitting spacers may cause undue stress on the bearings, lead to poor rolling, and result in quick damage. Choosing incorrect spacers might leave the bearings inadequately secure, allowing them to shift laterally as the wheel rotates.

Varieties of Spacers

The most frequently encountered spacers include:

• 6 mm spacers
• 8 mm spacers

6 mm Spacer

The 6 mm spacers feature an "additional ring" centrally located. They are compatible with 6 mm axles.

Consistently paired with 6 mm axles. The spacer is inserted between the two bearings, ensuring they remain firmly in position, and reduces the inner diameter of the bearings to 6 mm.

8 mm Spacer

These 8 mm spacers fit snugly between bearings with no "additional ring" visible from the side view. They are employed with 8 mm axles.

Universally used with 8 mm axles. The spacer is positioned loosely between the bearings, and it correctly aligns the wheel bolt during installation. This reduces the stress applied to the bearings.

Materials Used

Spacers are typically crafted from metal, though some may be manufactured from plastic. Plastic variants lack the durability of metal spacers and can fracture easily. We advise opting for metal spacers.

Mini/Micro (688)

Certain skates are produced with mini/micro bearings, necessitating unique spacers. Due to their smaller diameter, standard spacers are incompatible with micro bearings. SkatePro does not offer micro bearings or suitable spacers.
