Item # ACR075-6-4, Helical A Series Aluminum Couplings

  • Light to medium duty
  • Non-magnetic
  • Economical
  • No maintenance
The A Series coupling meets performance demands over a wide range of applications, including drive systems for encoders, instrumentation, lead screws, small pumps, feed rollers and anywhere a light to medium duty, torsionally flexible coupling is required. Helical's most popular coupling.

  • No maintenance
  • Shaft sizes from 3/32 to 3/4
An array of options, in a variety of diameter sizes, allows you to tailor the A or H Series to your specific applications. A and H Series options include set screw or integral clamp attachments and inch or metric bores.

Note
  1. Shaft misalignments:
    Angular 5 degrees
    Parallel Offset 0.030 in. (0.060 in. T.I.R)
    Axial Motion ±0.010 in.
  2. Manufacturing dimensional tolerances unless otherwise specified are:
    fraction ± 1/64
    x.xx ± .01 in.
1 Dynamic torque ratings are momentary values. For non-reversing applications, divide by 2. Divide by 4 for reversing applications. Should the torque ratings be marginal for your application.
2 Inertia is based on smallest standard bore diameter.
3 Metric Fasteners available on request
