The ball can be easily removed with a little force. Designed for right-handed trackball use, but can also be used for left-handed use. ※ Please understand that the connection between the bearing mounting hole and the print will be on the front side. Prioritizing smoothness (rotation) makes fine work unstable... Prioritizing fineness (stability) causes stress during large movements... The EN and KAKU created this time are balanced types. ⬜︎ About Bearings Compared to regular ceramic balls, the movement is smoother and improves operability, but on the other hand, a slight rubbing sensation and sound occur. Three high-precision NMB MinebeaMitsumi bearings (DDL-415X5ZZ) are used. It may seem a bit expensive, but it includes the cost of the bearings and screws x 3. Users only need to prepare a 25mm trackball to use it. ⬜︎ Two Designs EN, which has a rounded shape and a soft, slightly cute impression. KAKU, which has a solid and angular, cool impression.
