Split cast-metal clamp block that bolts around a blade's cylindrical root to lock it into the hub at a fixed pitch angle, shown across five sizes to match different blade-root diameters. Allows individual blade pitch adjustment and replacement without disturbing the whole hub.

Composite (FRP) equivalent of the cast-metal blade clamp, offered across a wider size range for larger or corrosion-sensitive installations. Two-piece design clamps around the blade root and bolts through the hub face; an assembled cube-style clamp is also shown.

Twin-disc flanged hub with a dense perimeter bolt pattern for mounting a full blade set plus a motor-side coupling flange. Its flat-disc design distributes blade loads evenly and suits fans requiring a rigid, low-runout mounting interface.

Cast hub with a dense radial bolt circle and a keyed center bore for direct shaft mounting, sized for a high blade count. Rugged cast construction handles the combined centrifugal and aerodynamic loading of large-diameter industrial axial fans.
