Tolerances: for d: h6; for H: ±0.2 mm

*You can shorten the magnet by this amount compared to the holding surface without reducing the holding force.

2) made of SmCo5, with extremely high adhesive force
  • Can be used at temperatures of up to 200 °C
  • Tolerances: for d: h6; for H: ±0.2 mm
  • approx. 5-fold holding force compared to conventional grippers
  • anisotropic

The dimensions are in accordance with the DIN 7168-m standard. General tolerances for length and angle dimensions.
H is the standard length of the bar gripper. h can vary from zero to the maximum value in the table.

The holding forces have been determined on a polished plate of ST37 with a thickness of 10 mm with vertical withdrawal of the magnet. A deviation of up to -10 % from the specified value is possible in exceptional cases. In general, the value is exceeded.

The dimension h indicates the length by which the bar gripper can be shortened without reducing the holding force. When installing in iron, it must be ensured that certain distances from the shell of the bar gripper to the iron are maintained so that no magnetic short-circuits occur. The distances must also be kept to the rear if the rod gripper has been shortened by the dimension h and is installed in iron. Please refer to the table for the distances.
