What is a straight end key?

One Straight end key is a mechanical part used to fix two mechanical elements. The most generally used example is that of the transmission of a rotational movement to a shaft and a hub. When the key is inserted into the groove (previously made on the shaft by a mortising machine), it prevents the hub from rotating around the shaft and thus ensures the transmission of rotational torque.

However, the straight wedge can be used in a wide variety of industrial and mechanical applications where the attachment of two elements is required. It is often used in industrial machines, motor vehicles, agricultural equipment, or other applications that require the transmission of power between two components.

We produce straight end keys in accordance with DIN 6885B, as well as according to the specific plans provided by our customers.

‍Characteristics of the straight end key

La Straight end key is a piece with a rectangular or square cross section and is characterized by two straight and parallel ends. It is generally used in applications that require unidirectional power transmission, without back-and-forth movement. It is important to note that the choice of a straight end key depends on specific application requirements, design constraints, tolerances, and other factors.

Materials used for the straight end key

La Straight end key is generally made from steel or stainless steel. However, at Gardette, we understand that each project may have different material requirements depending on its technical specifications, usage constraints, application environment, or others.

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

Steps in the manufacture of a straight end key?

1. Lamination: 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 allows us to manufacture a wide variety of standard and special profiles in various materials such as Steel.
   ‍
2. Cutting: Once the rectangular or square profile is obtained, cutting 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 present burrs and have a rough surface. To improve the surface condition of the parts, a vibratory finishing process is used to obtain a high quality finished product.
   ‍
4. Quality control: Finally, before being stored or shipped, straight end keys must undergo a quality check to ensure that they meet the required specifications and standards. This may include visual inspections, dimensional measurements, and other tests to ensure that the keys comply with quality requirements.
