BW-Fixators® – Series LK:

The BW-Fixators® of series LK have been invented especially for the anti-vibrant and loose alignment of machines. Due to a exceedingly long setting range of 10 mm uneven surface can be compensated easily.

With this series are two sizes availabe with load values from 30.000 N up to 55.000 N.

The adjustment is easy in opertation and safe from unintentional adjustment (e.g. vibration). The applications of these BW-Fixators® can be customized by a lot of diffrent variants. Diffrent isolation plates, made from multiple layers jute fabric combined with special bitumen under high pressure or isolation plates made of polyurethane allow the anti-vibrant alignment.

The time for the alignment of your machine 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.

The alignment can be done loose or with diffrent anchors.

Determining BW-Fixator® Sizes
Divide the total load ( machine weight and workpiece ) by the number of bearing points to determine the average load per mount. Select a mount size with an equal or greater recommended static load.
For machinery with sizable variations in partial weight, it is the heaviest machine load that has to be devided by the number of bearing points and the resulting BW-Fixator® size has to be used everywhere under the machine.
