The Sirui ball heads are manufactured with extreme precision and utmost care. The high quality of the tripod heads is ensured through high-end CNC milling and a premium surface finish. In the KX series, the tolerance between the ball and the bearing is a maximum of 0.01 mm.

The K-40X head operates particularly accurately and smoothly. With a load capacity of up to 35 kg, it holds your camera securely. The base plate can rotate 360°, making it ideal for panoramic shots. The locking knob for the ball can be limited by a scale at the end stop, allowing you to customize the head's mobility to suit your camera. This prevents, for example, the ball from loosening too much and causing unwanted tilting of the camera. The Safety Lock system prevents the quick release plate from accidentally slipping off.

The clamping mechanism for the quick release plate is compatible with the Arca Swiss system, allowing the use of various plates.
