    Length calculation:
L tot = total stroke * FBL + L + L4 + L5 + BB
Total stroke (GH) = effective stroke + 2 x S (mm)

ATTENTION: The allowance S designates a safety range suitable for the particular application.

Observe:

- The maximum possible support rail length L tot of the actuator.
1)   Lubrication nipple to DIN 3405-A M6.
2)   Filling openings.
3)   Switching tag connectors on carriage.

In the case of linear tables with trapezoidal lead screw drive, the maximum axial load is restricted by the spindle bearing arrangement.
Please consult us regarding the loading of the trapezoidal lead screw drive.

M0x per 1904  Nm  Permissible static moment rating (per carriage)

These values apply if load is evenly distributed over all four linear ball bearings.
Values are individual loads. If combined loads are present, these must be reduced.
For design criteria of the linear guidance system, see Catalogue WF1.
M0y per 1736  Nm  Permissible static moment rating (per carriage)

These values apply if load is evenly distributed over all four linear ball bearings.
Values are individual loads. If combined loads are present, these must be reduced.
For design criteria of the linear guidance system, see Catalogue WF1.
M0z per 1510  Nm  Permissible static moment rating (per carriage)

These values apply if load is evenly distributed over all four linear ball bearings.
Values are individual loads. If combined loads are present, these must be reduced.
