Detailed Performance Data for the TMC 600R on Round Pipes
Values shown for the performance of the TMC 600R are based on measurements made on round pipes with
material S235 JR, comparable to AISI 1020 Cold Rolled Steel, for the maximum, vertical breakaway force at
0° deviation from the load axis and a correct position in the groove of the magnetic contact area. These values do
not include any safety factor. The magnetic clamp will detach itself abruptly when the load exceeds values given in
table 3.

force
Avoid quick and abrupt rotations of the magnetic clamp especially when used on round objects
since the workpiece could disengage from the groove of the magnet causing a sudden reduction
of the load-bearing capacity.
