Made from aerospace-grade 7075-T6 solid aluminum, this product delivers an exceptional balance of lightweight design and superior strength.
Precision machining ensures tight structure and accurate fit. The superior sealing performance prolongs the service life of both bearings and wheels.
Specifically designed to block water from entering between the axle and collar at the wheel center, reducing moisture damage to bearings.
Equipped with fluororubber O-rings, offering excellent resistance to heat, oil, oxidation, and corrosion. And the corrosion-resistant surface treatment provides strong resistance to oxidation and corrosion.
Easy to Install: Before installation, apply a thin and even layer of grease to the O-ring inside the spacer. This prevents damage such as tearing, scratching, or deformation caused by dry friction, ensuring proper sealing performance and longer service life.
