MD64LB(M) hollow range

MD64LB(M) series

CF64, 4.5" OD flange, Hollow MagiDrive series

The MD64LB and MD64LBM MagiDrives provide high (8 Nm) or ultra-high (40 Nm) torque rotation through a high-stiffness coupling with a large 48.5mm clear bore. This rotary feedthrough is ideally suited to platen rotation or robot type applications. The MD64LBM supplies higher torque with the same dimensions.
