Description
1Ceramic bearing as an important mechanical base part， has excellent performance， high temperature resistance， super strength. 2Ceramics almost not afraid of corrosion， ceramic rolling bearing suitable for operation under harsh conditions full of corrosive media. 3Ceramic roll small ball much denser and lighter than steel， reducing centrifugal force of the outer ring by 40 per cent during rotation， greatly extending life. 4Elastic modulus of ceramics higher than steel， not easy to deform under stress， beneficial to improve working speed and achieve higher precision. 5Simple designed， easy to install and operate， convenient to use.Condition: 100% Brand NewItem Type: Ceramics Bearing Bottom BracketMaterial: Aluminium AlloyOptional Color: Black， RedQuantity: 1 SetSpecification: Thread Bottom Bracket， Suitable for Frame 68-73mm， Tooth Stripe BC1.37Bearing: Internal and External Circle: Stainless Steel(for AISI SUS316)Ball Bearing: ZrO2 Ceramics Material Weight: Approx. 122gInner Diameter: Approx. 24mm/0.94inchMaterial of inner and outer circle: The bottom bracket of bicycle needs high strength and impact resistance. If ordinary steel ring or plastic inner and outer ring used， easy to be broken or worn during a long ride. Therefore， imported stainless steel (for ALSI SUS316) is adopted.1 Set of Ceramics Bearing Bottom Bracket- Brand: Gegong
