Center Bolts

Short Description:

Center bolts are key connectors for core components of various large-scale equipment (such as centrifuges, crushers, wind turbines, etc.). They are mainly used to fix important joint parts such as rotating shafts and flanges, bearing seats and machine bodies, and are core fasteners that ensure the concentric operation and structural stability of the equipment.

Product Description

They are mostly made of high-strength alloy structural steel of grade 8.8 or above (such as 40Cr, 35CrMo). After quenching and tempering treatment, their tensile strength can reach 800-1200MPa, and they can bear radial force, axial force and torque load during the operation of the equipment. The surface is often galvanized or phosphated to enhance rust resistance and adapt to working conditions such as humidity and dust.

In terms of structure, the head is mostly designed with a hexagonal head or a round head, and the rod body is matched with fine threads to improve the anti-loosening effect. Some are equipped with positioning steps to ensure the installation concentricity. During installation, it is necessary to fasten evenly according to the specified torque to avoid component deflection caused by uneven force. Daily inspection of whether the bolts are loose or the threads are worn is required, and timely replacement is needed if problems are found. As the “central hub” of the equipment, its performance directly affects the operation accuracy and service life of the equipment.
