These movements are for standard Flexijoint® expansion bellows with Limitlink or limitbolts.

All movements must be assumed  concurrent. The sum of the movements must not exceed 100%. Therefore the % axial travel  + % lateral travel + % angular travel must be less than or equal to 100%.

Example:  If the movements required of a specific bellows were 60% of the maximum allowable axial travel shown in Table 1, 15% of the maximum lateral movement shown in Table 2 and 0% of the maximum angular movement shown in Table 3.

Adding these movements would yield  60% + 15% + 0% = 75%, or,  the  bellows selected is adequate.
