SIWAREX WL280 RN-S SA meets the accuracy class C3 according to OIML R60 standards. The load cell material is stainless steal and meets IP66 and IP68 degrees of protection for harsh environments. WL280 RN load cells with a rated load up to 13t are also equipped with integral overload protection. Due to its low installation dimensions, the load cell can be applied to a wide range of applications. The large number of mounting accessories including self-aligning bearing, elastomer bearing, guide elements make the load cell exceptionally versatile and provide secure installation as well as optimal flow of forces.

Installation Accessories

We offer the following accessories for ring torsion load cells

Mounting unit and guide element SIWAREX WL280 RN-S SA

Together with the load cells of the SIWAREX WL280 RN-S SA series, the compact mounting unit forms a self-aligning bearing unit. The guide element can be mounted on the front or the back of the compact installation unit. If needed, two guide elements can be used in order to double the transverse force that can be applied.


The load cell is not part of the scope of delivery of the compact mounting unit.

Self-aligning bearing SIWAREX WL280 RN-S SA

The self-centering self-aligning bearing for SIWAREX WL280 RN-S SA load cells is particularly suitable for container and platform scales due to its low mounting height.

Elastomer bearing SIWAREX WL280 RN-S SA

Used in combination with the self-aligning bearing base part, the self-centering elastomer bearing for SIWAREX WL280 RN-S SA load cells is the ideal load introduction element for scales without guide elements. It is used in container, platform and roller table scales and dampens vibrations and shocks.
