    2.3 mm Amplitude mark (lower vibrator) (Note) When a recommended speed is designated by NTN, adjust the volume position to the recommended scale. [2] Caution in attaching and detaching leaf spring When attaching and detaching the leaf spring, be sure to complete one unit before moving to the next unit.
  • Page 9 (b) Assemble the leaf springs and spacers after applying grease or rust preventive oil between them. ( ( Note 1) Be careful not to include dirt, chips and others between leaf springs. (Note 2) As to K14, K16 and K20, press the leaf springs against the body side and align their end faces before assembly.
  • Page 10 The clearance between the magnet and the moving iron core (K10 is upper vibration) is set to a value shown in the following table when the body is shipped from NTN. But, since minimization of the clearance is advisable to the extent not to allow contact of them with each other at the occasion of maximum amplitude, check the clearance from time to time to keep a proper value.
  • Page 11 (3) Change of power frequency The power frequency of the NTN bowl feeder is adjusted in conformance to the value applicable to the area where it is used or the preset frequency for the controller. Accordingly, normal vibrations cannot be ensured, if the power frequency or the preset frequency for the controller as the output frequency for driving should change.
