These maximum operating alignment limits are each based on 3/8° per flex half coupling. Combined values of parallel and angular misalignment should not exceed 3/8°. Type
GL slide couplings are limited to 1 / 4° per flex half. Application requirements in excess of these values should be referred to the Falk for review.
