The ball can be easily removed with a little force. Designed for right-handed trackball use, but also usable for left-handed users. ※ 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・KAKU created this time is a balanced type. ⬜︎ About Bearings Compared to regular ceramic balls, the movement is smoother and improves operability, but on the other hand, a slight rubbing feel and sound will occur. Three high-precision NMB MinebeaMitsumi bearings (DDL-415X5ZZ) are used. It may feel a bit expensive, but the price includes the bearings and screws x 3. Users only need to prepare a 25mm trackball to use it. ⬜︎ Compatible Balls Compatible balls are Perixx 25mm balls. It also supports POM balls, but due to individual differences in size, if the sliding is poor during operation check, fine adjustment is required by loosening the center bearing. ⬜︎ Two Designs EN, which has a rounded shape and a soft, slightly cute impression. KAKU, which is solid and angular, with a cool impression.
