Description
Variable springs are placed on top of the support structure and are designed for use when spring adjustments are made from above.
1. The casing diameters shown for each spring hanger size are for all types of spring hangers.
2. The casing lengths shown are for Type D and E spring hangers.
3. All Maximum Overall Length values shown in the table for Type D spring hangers are calculated with the spring hanger at the top of the movement scale. All Minimum Overall Length values shown in the table for Type D spring hangers are calculated with the spring hanger at the bottom of the movement scale. To obtain the actual shipping length, subtract from the maximum overall length the deflection from the top of the scale (top of the working range) to the preset position.
4. For Type E spring hangers, the Maximum Overall Length is equal to the Casing Length B.
