B4 325  mm   
H 100  mm   
L 325  mm   
    Length calculation:
L tot = total stroke + L + L4 + L5
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.

High precision linear tables are supplied with a symmetrical hole pattern.
With a symmetrical hole pattern, aL = aR.

Calculation of hole pattern:

The number of hole pitches is the whole number equivalent to:

n = (L2 - 2 * aRmin) / jL8

The spacing aL between the end of the support rail and the nearest hole centre point is calculated from:

aR, aL = 0,5 * (L2 - n * jL8)

M0x per 18000  Nm  Permissible static moment rating.

The values are individual loads and are valid when the underside of the actuator is fully supported.
If combined loads are present, the values must be reduced.
Design criteria of the linear guidance system: see Catalogue PF1, Monorail Guidance Systems.
