Weld-on Hinge D20, L180mm

Weld-on gate hinge with bearing, steel, O 20 mm, length 180 mm

Product code: D4/11-180

The weld-on hinge D4/11-180 is designed for secure and reliable attachment of metal gates, wickets, and other rotating steel structures. Thanks to its robust steel construction and integrated bearing, it allows smooth opening and closing of the gate leaf and provides a practical solution for creating a strong and durable pivot connection.

The hinge is equipped with a bearing that helps reduce friction between moving parts and contributes to smoother operation even under higher loads. Thanks to its extended design with a length of 180 mm, it is suitable for manufacturing heavier metal gates, assembling steel structures, well for repairs and renovations of existing gate systems.

Material

Steel with integrated bearing.

Surface finish

Without surface treatment (natural). The steel surface allows direct welding of the hinge to the metal structure. After welding, it is recommended to apply suitable anti-corrosion protection to ensure resistance to weather conditions.

Dimensions and technical parameters

– Hinge len(H): 180 mm

– Hinge diameter (D): 20 mm

– Dimension B: 25 mm

– Gate weight Gmax/Goptimal according to manufacturer: 100 kg

– Material: steel

– Mechanism: with bearing

– Surface finish: without surface treatment (natural)

– Mounting method: by welding

– Design: cylindrical weld-on hinge

– Application: metal gates, wickets and steel structures

Installation and compatibility

The hinge is designed for direct welding to the metal structure of the gate and the supporting post or frame. The individual parts of the hinge are welded to the respective structural elements so that, after their connection, they allow free rotational movement of the gate leaf.

During installation, it is necessary to ensure the correct position and alignment of the hinges to prevent excessive stress on the rotating mechanism. The bearing must be protected from excessive heat during welding, which could negatively affect its functionality and lifespan.

The manufacturer's stated Gmax/Goptimal value is 100 kg. When selecting and installing, it is necessary to consider the dimensions, weight, and construction of the gate leaf, well the number of hinges used and their fastening method.
