DKN- Miniature Metal Bellows Couplings

• Servo Quality Extremely high torsional
  stiffness. For use anywhere position accuracy is
  absolutely critical. Excels in high speed
  reversing applications, with no need to de-value
  coupling ratings.
• Shaft Misalignment Reduces bearing wear by
  compensating for lateral, angular and axial shaft
  misalignments.
• Low Inertia Stainless Steel bellows and
  Aluminum hubs keep the weight low, which keeps
  inertia to an absolute minimum.
• Cost Savings Manufactured in Chicago, IL.
  Rimtec DKN couplings are very price competitive,
  and their superior performance saves money in the
  long run by reducing bearing wear and machine
  downtime.

DKN Dimensions (mm)

• STANDARD BORE SIZES 3 mm, 6 mm, 8 mm, 10 mm, 12
  mm, 14 mm, ¼, 3/8, ½, 5/8, ¾.
• Hubs made of AlCuMgPb, available in steel on
  request.
• Transmission of the couplings nominal torque (M)
  is only quaranteed for bore sizes within the
  recommended range with standard H7 bore
  tolerances, unless otherwise specified. Other
  special bores can, however, be supplied by the
  manufacturer. All hub bores are supplied to fit
  standard H7 according to the customers data.
• Clearance of keyway, standard Js 9.

DKN Technical Ratings
The dimensioning of the couplings is always based
on the peak torque (Mmax) which is to be
transmitted regularly by the drive motors. For
basis of the calculation of the couplings rated
torque, see ordering data. The couplings, under
no circumstances, should be submitted to a torque
greater than 2.5 times the rated torque.
