What is a straight-end key?

A straight-end key is a mechanical part used to fasten two mechanical elements. The most commonly used example is the transmission of rotational movement between a shaft and a hub. When the key is inserted into the keyway (previously made on the shaft by a mortising machine), it prevents the hub from turning around the shaft, thus ensuring torque transmission.

However, the straight-end key can be used in a wide variety of industrial and mechanical applications where the attachment of two components is required. They are often used in industrial machinery, motor vehicles, agricultural equipment or other applications requiring the transmission of power between two components.

We produce straight-end keys to DIN 6885B, as well as to customer-specific drawings.

‍Features ofthe straight-end key

La clavette form B (bout droit) est une pièce de section rectangulaire ou carrée et elle est caractérisée par deux extrémités droites et parallèles. Elle est généralement utilisée dans les applications nécessitant une transmission de puissance unidirectionnelle, sans mouvement de va-et-vient. Il est important de noter que le choix d'une clavette bout droit dépend des exigences spécifiques de l'application, des contraintes de conception, des tolérances et d'autres facteurs.

Materials used for straight-end keys

La clavette forme B est généralement fabriquée à partir d'acier ou d'acier inoxydable. Cependant, chez Gardette, nous comprenons que chaque projet peut avoir des exigences de matériaux différentes en fonction de ses spécifications techniques, de ses contraintes d’utilisation, de son environnement d’application ou autres.

That's why we strive to offer you a complete range of materials to meet your specific needs.

How to make a straight-end key ?

1. Rolling: The raw material, usually steel or stainless steel, is rolled and then drawn to produce a rectangular or square profile. At Gardette, we have expertise in cold rolling, drawing and heat treatment. This know-how enables us to manufacture a wide variety of standard and special profiles in different materials such as Steel.

2. Parting: Once the rectangular or square profile has been obtained, parting machines, such as circular or band saws, are generally used to cut the parts to the required length.
   ‍
3. Tribofinishing: After the milling operation, the keys may show burrs and have a rough surface. To improve the surface finish of the parts, a tribofinishing process is used to obtain a high-quality finished product.
   ‍
4. Contrôle qualité : Enfin, avant d'être stockées ou expédiées, les clavettes forme B doivent subir un contrôle qualité pour s'assurer qu'elles répondent aux spécifications et aux normes requises. Cela peut inclure des inspections visuelles, des mesures dimensionnelles et d'autres tests pour garantir la conformité des clavettes aux exigences de qualité.
