■ Verification of load capacity Verification of the load capacity assumes the knowledge of the forces acting on the rails in the different directions, divided into prin cipal components correspondent to the values indicated in the tables of the product pages: radial loads, axial loads and moments.

For the telescopic rails TLAX, verification is mainly involves comparing the load capacity C 0rad to Pe, including a safety factor S 0 .

Pe <= C 0rad / S 0

Fig.15

Where S 0 is the safety coefficient as per below table

Safety coefficient - S 0

Application conditions

Neither shocks nor vibrations, smooth and low-frequency reverse, high assembly accuracy, no elastic deformations

1 - 1.5

Pe

1.5 - 2

Normal installation conditions

Shocks and vibrations, high-frequency reverse, significant elastic deformation Tab.6

2 - 3.5

For telescopic rails TQAX the calculation might also includes moments and axial load. ( ) Me x M x Me y M y Me z M z + + + Pe ax C 0ax Pe rad C 0rad + <= 1 S 0

Where: Pe rad = applied radial load Pe ax = applied axial load Me x *, Me y , Me z = applied moments

C 0rad = radial load capacity C 0ax = axial load capacity M x , M y , M z = moment capacities *Me x moment exist only in case of use a single telescopic rail

If using a single telescopic rail, the values C 0rad , C 0ax , M y and M z in the formula Fig.16 must be divided by 2 (M x is always and only referred to a single rail).
