ABOUT OUR BEARING CHOICES
Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime Warranty.
WS2 Coated Ceramitech Bearings: We took our amazing Ceramitech bearings and added an extremely durable, tungsten disulfide (WS2) coating that has a 0.03 coefficient of friction---which means it’s slicker than Teflon, graphite, and even molybdenum disulfide. WS2 has an affinity for oils and greases, which means it maintains a hydrodynamic layer of lubricant where it’s needed most. The result is astonishing spin performance and increased endurance. These bearings feature mid-contact seals for extreme performance and durability. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime Warranty.
ABEC-7 Steel Bearings: Crafted from SAE 52100 chrome steel, our BBInfinite ABEC-7 (ISO 492, Class 4) bearings are so buttery that you’d have to buy our Ceramitechs to find anything better. These bearings feature mid-contact seals for extreme performance and durability. Each bearing comes lubricated with Kluber or Koyo. 1-Year Bearing Exchange Warranty.
