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.

Unit of Measure: Imperial Metric Both
