Notes: Maximum recommended misalignment - 1/32 inch parallel, 1° angular.
Coupling permits wide latitude in shaft lengths. However, suffi cient spacing between
shaft ends should be provided to allow for shaft end play.
It is suggested that all designs for Spool-Type Flexible Couplings be reviewed with
LORD Corporation.
Construction: Rubber elements - LORD does not supply hubs, elements only;
Metal parts - steel; Flexing element - environmental-resistant elastomer.
