RNCBMX TITANIUM CERAMIC BOTTOM BRACKET BEARINGS

The lightest and strongest bottom bracket bearings ever made for BMX!

Races are CNC machined from heat treated and aged 6al-4v with a tensile strength of 170,00 psi then electroless nickel silicon carbide plated. The electroless nickel creates a layer of 70 rockwell plating with the silicon carbide nano particles being a 9.5 on the mohs scale nearly as hard as diamond for long lasting bearing life.

The balls are Silicon nitride Si3n4. These are the toughest and strongest grade of ceramic balls made and are comparable to the strength of steel. Our bearings our full compliment bearings meaning that there are no cages or spaces between the balls. Our bearings have 20 balls compared to standard steel bearings that have 10 for twice the load bearing capacity. Also our bearing races are twice as deep as a standard steel bearing creating even more surface wear area and strength.

The seals are all cnc machined from PTFE teflon for long lasting smooth frictionless operation
