BW-Fixators® – Series S:

The series S has been developed especially for big tooling plates and tables because with most of them the alignment from the side is not possible. The leveling elements are only accessible from the top. This is why the series S is adjustable from above, the adjustemt can be done via the fixing srew. Series S has a setting range from 8 mm (size S I) to 20 mm (size S V).

BW-Fixators ® series S are easy to operate and to adjust with precision. The time for the alignment will be reduced significant. If the machines needs to be re-adjusted because of foundation shifting or shrinkage, it can be done simply and fast. With it’s accessory and anchoring methods the series S covers a wide range of applications.

Matching with the recesses of series S the holes can be closed with our series D.

1) Standard approach for determination of BW-Fixator® size.
2) The operating range will be covered when the floor plate has been levelled and bound
down with the anchor bolts.

Formula for calculating the Resilience of BW-Fixators® Serie S

Note:
The total of the forces a – e exerted must not exceed the permissible maximum load.

a) Proportional machine load
b) Tensile force exerted by anchor bolt
c) Dynamic forces
d) Changing loads (moving machine parts or workpieces)
e) Forces counteracting moments
