Basic Specification

The main model of three leaf fingertip gyro is 608 bearing, and the size is 8 * 22 * 7mm.

The bearing materials mainly include ceramic stainless steel hybrid bearing, stainless steel bearing and all ceramic bearing. Ceramic balls are divided into zirconia (white ball) and silicon nitride (black ball),

Of course, silicon nitride is better in performance and more expensive. The bearing is also equipped with cage and dust cover.

The with cage is relatively more stable. The dust cover can prevent dust and avoid frequent shaft washing.

If you want to replace the bearing and don't know the model, take a ruler to measure the inner diameter, outer diameter and height of the bearing to determine the size and model of the bearing.

For different materials, there are different properties, which can be purchased according to needs and cost performance.

In addition, a word of caution, generally do not choose steel ball bearings. Even if you want to use them, you must choose those without grease, because the later maintenance is very troublesome.

Ceramic stainless steel hybrid bearing or all ceramic bearing can be selected.
