Classic Zealous longboard bearings
The first bearing in the world to be built specifically for longboarding. In particular downhill skateboarding. So you know these bearings will be fast and stand up to any condition.
Standard skateboarding is done under tame conditions, you could even say fake conditions. Super smooth concrete, ramps and transitions give you speed, many parks are under cover so your wheels never get wet. Longboarding is different, we push on the flat, we skate in the rain, our wheels go through everything from dirt to snow. So Zealous designed a bearing that outperforms all others, no matter how real the conditions. That is why longboarders keep recommending Zealous bearings.
The secret to Zealous is their custom nanoceramic grease. The nanoceramic compound fills in deformations or asperities in the bearing. These deformations cause friction and heat around them which hardens the nano-ceramic compound to that specific area. This micro coating is 5 times the hardness of the host alloy and has a molecular bond with the host metal, filling in all the asperities and eliminating friction over time.
The coefficient of friction is the lowest in the field of Tribology at 0.003% creating a near frictionless surface. Mainly because the nanoceramic compound eliminates all asperities.
Extremely low water washout
Corrosion on the inside of the bearing is nearly eliminated, which makes the bearings last a long time.
Precision 8mm axle holes
.4045″ built in spacers
.5mm built in speedrings
Green rubber seals to keep dirt and debris on the outside of the bearing.
Sold in sets of 8 bearings (enough for one set of longboard wheels).
