B1 280  mm   
H 115  mm   
L 280  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.

jL8 200  mm  Location of support rails:
As standard, the support rails 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 = (Ltot - L4 - L5 - 2 * aRmin) / jL8

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

aR, aL = ( Ltot - L4 - L5 - n * jL8)

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.
