Regardless of the fixtures/fasteners you decide on, please make sure during installation that the contact area of the rollers has direct contact with each device. When making bolted connections, ensure sufficient screw strength (property class min. 8.8 or comparable). The minimum screw torque must comply with the technical directives. Bolted connections must be permanently secured against independent loosening. The stated load-bearing capacities are based on these installation instructions.
