1. Couplings: Core parts to transfer motion and power that can absorb mis-alignments and vibration for accurate rotation
2. Support Units: Be well-standardized and have very precise straightness, squareness and concentricity for Ball-screw support.
3. Power-lock: Parts to clamping a shaft with a hub(ex. Pulley) very precisely and strongly
4. Connecting Shaft: To transfer motion and power to a long-distance target with Couplings and well-processed shaft
5. F.A Parts: Set-Collars, Bearing Units.
