Heavy-Duty Forged Ring Housing


The precision-machined flanged safety pin base is integrally forged and manufactured through CNC turning from a forged blank. The structure features dual-end flange plates combined with a central stepped transition shaft body. Multiple groups of bolt holes are evenly distributed along the circumference of the flange end faces on both sides, enabling multi-point fastening connections with the main equipment structure and matching components. The middle shaft body is designed with a precision internal bore and keyway structure for the installation of safety pins or limit interlocking mechanisms, with the internal bore concentricity and keyway dimensions precisely controlled.
The product features a dense internal structure without shrinkage cavities or slag inclusions, providing excellent impact resistance and fatigue resistance. The surface is precision turned to achieve a uniform and smooth metallic finish. The flange end faces are flat, the hole distribution is regular, and the product offers excellent batch consistency and assembly interchangeability.
Available materials include carbon steel, alloy steel, and stainless steel, with specifications and dimensions customizable according to customer drawings. It is widely used in wind turbine yaw/pitch safety interlocking systems, lifting equipment limit protection devices, metallurgical rolling mill safety systems, and other mechanical interlocking applications requiring high reliability and safety performance. It serves as a critical fundamental component for ensuring the safe operation of equipment.
