MD40 solid range

MD40 Series

CF40, 2.75" OD flange, Solid MagiDrive series

The MD40 rotary feedthrough provides 9Nm break-away torque on a CF40 flange. For lower torque requirements on the same flange, the MD40N and MD40A provide 0.45Nm and 1.8Nm break-away torque for low- to medium-torque applications.

The MD40 provides 9Nm break-away torque and is ideal for applications where a high degree of stability is required.
