Full definition
Device joining two perfectly collinear shafts without permitting any misalignment, transmitting torque and speed with zero elasticity loss. Types include split sleeve (clamp), flange, and clamping cone designs. Requires precision alignment better than 0.05 mm offset and 0.05 mm/100 mm angular per ISO 10816. Transmits full rated torque without dampening vibration. Material: ductile iron or steel. Used where precise shaft positioning is critical, such as precision machine tools and test rigs. Standards: AGMA 9002, DIN 116.
