If increased demands are made on system accuracy we recommend supporting the linear modules along its entire length.

The maximum permissible deflection is limited by the maximum deflection angle of 5’. Exceeding this value without support will have a negative effect on the unit’s service life.

Linear modules may be assembled self-supporting. However, the deflection (which limits the possible load) must be taken into consideration.
