Bar couplings / grub screw clamping / body: plastic / UJ / ADVANCED

· Miniature coupling making full use of engineered plastic fatigue resistance
· It has excellent resistance to bending fatigue as compared with metals such as aluminum alloys, realizing light and smooth rotation transmission
· For light load transmission such as those from rotary switches, encoders, or small motors
· For rotation transmission parts that require electric insulation
