| Notes: |
* |
S.E.(1) signifies a single-ended unit with only one (1) elastomeric element. |
|
** |
Axial tension, internal pressure and angular rotation are interactive functions and the ability to achieve the maximum stated condition for one function is based on the magnitude of the other two. Refer to the load cases for details. |
