Good Value
Works well after lubrication. Slightly tight at first.
Description
Each bushing includes 2 set screws; each order comes with one wrench! Compatible with 2.3mm shaft motors such as 380, 385, 390, 395, etc. Also fits 3.17mm shaft motors including 555, 545, 550, and 540. The key feature is detachability! Overall length is slightly longer, so precision may be slightly lower than fixed bushings. Advantage: detachable design!
