ZEALOUS Ceramic – Built In Ceramic Bearings for Longboard, Skate and Cruiser
The ZEALOUS Ceramic Bearings are high-performance ceramic bearings designed for riders looking for maximum rolling efficiency in longboard, skateboard and cruiser setups.
They combine ceramic balls, Built In spacer and speedring technology, reinforced nylon ball retainers and ZEALOUS Custom Nanoceramic Grease to create an extremely smooth and fast-running bearing.
Widely suited to demanding disciplines such as longboard downhill and freeride, they are also an excellent upgrade for cruising, carving and everyday skateboarding.

CERAMIC BALLS: LIGHTER, STIFFER AND SMOOTHER
The main difference between the ZEALOUS Ceramic and conventional steel bearings is the use of ceramic balls.
Ceramic balls are lighter, stiffer and naturally corrosion resistant. Their properties allow ZEALOUS to use a lower-viscosity lubricant, helping the bearings feel fast and smooth straight out of the package.
For riders focused on speed and efficiency, this translates into a particularly smooth rolling feel with very low friction.
----
BUILT IN: INTEGRATED SPACER AND SPEEDRING
Like the ZEALOUS Classic, the Ceramic uses the BUILT IN system, with the 0.4045" spacer and 0.5 mm speedring integrated into the bearing.
This means you don't need to install separate spacers or speedrings when mounting your wheels.
The result is a cleaner and faster setup, with fewer loose components and a precise connection between the bearing, wheel and axle.
For downhill and freeride riders who regularly change wheels, this is a particularly useful feature.
Fit the bearings, install the wheels, tighten the axle and ride.
----
CUSTOM NANOCERAMIC GREASE
ZEALOUS Ceramic bearings are lubricated with Custom Nanoceramic Grease, a specialized lubricant designed to reduce friction inside the bearing.
According to ZEALOUS, the nanoceramic compound fills microscopic imperfections in the bearing surfaces. These imperfections can generate friction and heat; the compound forms a very hard micro-coating that bonds to the metal surface and progressively fills these irregularities.
ZEALOUS states a coefficient of friction of 0.003, together with greatly reduced internal corrosion.
Combined with the ceramic balls, this lubricant is a key part of the Ceramic's low-friction performance.
----
REINFORCED NYLON RETAINERS AND WHITE RUBBER SEALS
The Ceramic model uses strengthened nylon ball retainers designed to securely control the ceramic balls inside the bearing.
The white rubber seals help keep dirt and debris outside, protecting the internal components during use.
This combination makes the Ceramic suitable not only for competition-oriented setups but also for riders who want a high-end bearing upgrade for regular skating.
----
BUILT FOR DOWNHILL — PERFECTLY VALID FOR EVERYTHING ELSE
The ZEALOUS Ceramic has the performance characteristics expected by riders in longboard downhill and freeride, where every reduction in rolling resistance matters.
But these are not bearings that should be reserved exclusively for racing.
They are an excellent choice for:
- Longboard Downhill
- Longboard Freeride
- Longboard Cruising
- Carving
- Cruiser Skateboards
- Skateboarding
- Riders looking for ceramic longboard bearings
- Riders who want Built In bearings with integrated spacer and speedring
If you want to make a noticeable upgrade to the rolling performance of your longboard, cruiser or skateboard, the ZEALOUS Ceramic offers a combination of technology and convenience that is difficult to match.
