B1 180  mm   
H 67  mm   
L 180  mm   
    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.

M0x per 540  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 503  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 393  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.
