[Cylinder rotates first, then clamps – workpiece remains distortion-free]: If rotation and clamping occur simultaneously, the workpiece may become distorted or damaged. This design ensures that the full rotation is completed before clamping force is applied. The workpiece remains square and free from marks. [Rotary shaft features a double seal]: A single seal will wear out and leak after several thousand cycles. This cylinder features a double-seal design in the rotating section. The second seal acts as a backup for the first. [Cylinder body anodised – not merely painted]: Painted cylinders may flake in damp or dusty environments. The surface will not flake, and the cylinder body remains rust-free for much longer. [Clamping arm with built-in guide pins – no lateral wobble]: Without a guiding mechanism, the clamping arm may wobble and miss the workpiece. This clamping arm has a built-in guide pin. It moves in a straight line, ensuring accurate clamping every time. [Built-in 90° hard stop – no damage from over-rotation]: Some cylinders rely on external stop blocks, which may become dislodged. This cylinder has a built-in hard stop. It stops precisely at 90° every time. There is no need to adjust external stop blocks., Manufacturer: AURVIX
