4 Lamina ball-bearing retainers (AR1) are made of a heat-treated aluminum alloy that combines lightness and strength. Each retainer is quality inspected for dimensional tolerance and all burrs are removed prior to ball insertion. Ball bearings are of the highest quality AAA1 Grade (25 millionth class), continually inspected to meet our exacting tolerance. After the ball bearings have been inserted into the retainer, they are then staked using Lamina’s unique method that allows free movement with maximum security.
