Quantum Bearing Science

Enter the Isotope ceramic hybrid series. A bearing designed for the high impact street/park skater that is looking for the speed and performance of a ceramic bearing with the mechanical durability of an all metal design. It's a highly versatile...

As part of TJ’s signature bearing development process, we wanted to design a bearing that matches his style – smooth & fluidic while also allowing the bearing to keep this performance under high impact and tough terrain Features: Precision design...

Protect your investment in your bearings and your trucks. Bearing presses are nice but large and not suitable for the skater on the go. Removing precision bearings using truck axles can strip the axle thread, damage the bearing outright, and/or...

Skate bearings take a beating and need a little TLC… especially precision bearings. Improve your bearing lifetime and keep your bearings running smooth and fast with Graphflo StackZ high performance skate bearing lubricant. This formulation was developed from the ground...

Sometimes you just need extra speed to clear the gap. Atom series bearings can help. As with all Quantum bearing products, they only start with high purity, high quality carbon steel for the inner/outer rings, Si3N4 ceramic roller balls for...

Great ceramic bearings should not be elusive or ridiculously expensive. Enter the Isotope series bearings. As with the Metallics and Atoms, Quantum Bearings start with high purity, high quality carbon steel for the inner/outer rings, ZrO2 ceramic roller balls for frictional/thermal/shock/impact...

A twist on the classic. The Metallic series bearings are made with high purity, high quality carbon steel for the inner/outer rings and roller balls. Then they run the raceways and roller balls through a proprietary diamond finishing process. From...
