Remarks:
1.""means it can be manufactured on the condition of the diameters listed in the table."- "means can not be manufactured.
2.The magnetic bars which their diameter are less than 38mm often use Smco Magnet in EH temprature interval.
But if their diameter are more than 38mm will not consider using Smco Magnet.
3. The related Max working temperature from different series.
H series: 120
SH series: 150
UH series: 180
EH series: 350
