A new series of inch and metric flexible helical couplings from Sterling Instrument (An ISO 9001:2000+AS9100B Manufacturer) feature one-piece anodized aluminum construction with set screw type or integral clamp split-hub type designs for fastening to both shafts. They have the ability to adapt to both high- and low-speed applications with a high level of fatigue resistance. Their angular misalignment compensation is 5°, with a maximum parallel offset range of 0.25 mm (±.010"), and an axial motion range of 0.25 mm (±.010").

Identified as the S50HAWM (Metric) and S50HAA-
(Inch) Series, they are designed to fit shafts ranging in diameter from 3 to 12 mm in metric and 3/32" to 1/2" in inch sizes. Their O.D ranges from 15 to 30 mm in metric and 3/8" to 1-1/8" in inch. Lengths are available from 22 to 38 mm and from 3/8" to 1-1/2".

Detailed specifications are contained in SI Catalog D785 (Metric) and SI Catalog D790 (Inch), both available free upon request.
