High hardness bearing steel: made of high-quality bearing steel, durable, not easy to deform under heavy loads. It is stronger than carbon steel and can be used for a long time.
Dimensional accuracy: The more accurate size is 8mmx22mmx7mm.
Double iron seal: Protective covers on both sides prevent lubricant ingress and prevent contaminants from entering.
Wide range of applications: ideal for medium duty use: skateboards, inline skates, scooters, 3D spool roller projects and other skating applications.
High load-bearing, low noise, high speed.
