💡 Why choose a ceramic hybrid ABEC-5 bearing?
Ceramic hybrids bring the best of both worlds:

• Lower rolling resistance for higher RPMs

• Longer service life due to reduced wear

• Corrosion resistance with stainless steel races

• Smooth, quiet operation even under high speed

If you want a bearing that runs cooler, faster, and lasts longer, this one’s ready to roll.
