BettaBetta Full Ceramic Bearings 3x8x4mm 2-Pack
Main highlights- The elastic modulus of ceramics is higher than that of steel, and it is not easy to deform when subjected to force, so it is beneficial to improve the working speed and achieve higher precision.
- The density of ceramic rolling balls is lower than that of steel, and the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended.
- Inner diameter 3mm. Outer diameter 8mm. Thickness 4mm. 2 pcs per pack. Quality guaranteed.
- High degree of corrosion resistant. Ideal for being used in any harsh conditions.
- Ceramics are less affected by thermal expansion and contraction than steel, so when the bearing clearance is constant, the bearing can be allowed to work in an environment with severe temperature difference.
