Quantum Bearing Science Isotope Series Ceramic Hybrid Skateboard Bearings Kit
SKU: QBS802
Description
Keep your speed on the streets with Quantum Bearing Science Isotope Series ceramic hybrid skateboard bearings, which Quantum calls the only ceramic hybrid on the market designed for high impact street and park skating. They deliver the speed and performance of a ceramic bearing with the mechanical durability of an all metal design, from street sessions to backyard ramp jams.
Isotope bearings feature high precision chrome steel inner and outer rings, doped zirconium oxide (ZrO2) rolling elements for frictional, thermal, shock, and impact resistance, diamond polished raceways and rolling elements, a high strength thermoplastic cage, and Quantum's Graphflo engineered lubrication process. Every bearing is burned in at high speeds and tested before it ships.
Who Quantum Isotope Series Ceramic Hybrid Are For
- Street and park skaters who want ceramic speed
- Skaters who land hard
- Riders who skate everything from street to ramps
- Anyone upgrading from all-steel bearings
Features
- High precision chrome steel inner and outer rings

FAQ
What's a ceramic hybrid bearing?
It pairs steel rings with ceramic rolling elements. Isotope uses chrome steel rings and ZrO2 rolling elements for ceramic speed with the durability of an all metal design.
What's the difference between Isotope and Atom?
Isotope uses ZrO2 rolling elements and is designed for high impact street and park. Atom uses Si3N4 rolling elements and is designed for transition and cruising.
What comes in the kit?
8 bearings, 16 frictionless shields (8 installed, 8 spares), 8 speed washers, 1 tube of low-viscosity bearing lubricant (2ml, single use), and 1 sticker.
Do these come with spacers and speed washers?
Speed washers are included (8 per kit). Spacers are not included.
