Weight reduction of all-aluminum bearing rollers with a diameter of 19 mm, which is popular among rollers.
By changing the 6 holes and the shape, we have achieved a weight reduction of about 30% in the aluminum part.
Smooth rotation with 520 ball bearings embedded in the bright blue roller body is also attractive.
In addition to 2 rollers, 2 mounting screws and 4 aluminum spacers are also included.
