8mm Floating Bearing Spacers (single)
Bearing spacers are a critical part of the wheel assembly of inline skates. Each wheel needs a bearing spacer in its core between the two bearings, to keep them from compressing the wheel and slowing its rotation when the wheel is attached to the skate. Floating spacers have a ring around the center to help keep the spacer in place and make assembling wheels easier.
IMPORTANT: Some aggressive wheels are not compatible with this type of spacer because they have less space inside the core of the wheel and will require 8mm spacers without a ring.
