Zealous Ceramic Built In Bearings
Zealous bearings are considered the best in the industry. they are fast, durable and have load-bearing shields on both sides to prevent dirt from entering. these are definitely worth a try!
Ceramic balls are lighter, stiffer, smoother and naturally corrosion resistant. This means we can use a lower viscosity lubricant, making them fast from the moment they come out of the package.
Precision 8mm axle holes
.4045″ built-in spacers
.5mm built-in speed rings
Reinforced nylon ball retainers
White rubber seals to keep dirt and debris on the outside of the bearing.
Lubricated with custom Nanoceramic grease
-The unique feature of our lubricant is how the nanoceramic composition fills deformations or asphericities in the bearing. These deformations cause friction and heat around the deformations, causing the nanoceramic composition to harden in that specific location. This microcoating is 5 times as hard as the host alloy and has a molecular bond with the host metal, filling in all asphericities and eliminating friction over time.
-The coefficient of friction is the lowest in the field at 0.003% tribology, creating an almost frictionless surface. Mainly because the nanoceramic composition eliminates all asphericities.
-Corrosion on the inside of the bearing is almost eliminated.
Sold in sets of 8 bearings.
