2-4.5 X 10 OVAL HD LINER BOLT SAE GRADE 5, 3/4 PARALLEL

A liner bolt is a specialized, heavy-duty fastener engineered specifically to secure wear-resistant liners to the inner shell of grinding mills, crushers, and other heavy rotating equipment. Its primary purpose is to protect the structural integrity of the mill shell from the intense impact and abrasion of the grinding process, ensuring the machine's longevity and safe operation.

While they may look like simple bolts, they are designed to endure dynamic loads, extreme vibration, and often highly corrosive environments. Their role is crucial across several key industries.

• Mining Industry: They are essential for securing liners in Ball Mills, SAG (Semi-Autogenous Grinding) mills, and AG (Autogenous Grinding) mills, which are the workhorses of mineral processing.
• Cement Industry: They are used to fasten liners and refractory bricks in cement kilns and raw meal grinding mills, where high temperatures and abrasive materials are the norm.
• Power Generation: Key applications include coal pulverizers and other abrasive material handling equipment where protecting machinery from wear is paramount.

Unlike a standard structural bolt, which is designed for static shear and tensile loads, a liner bolt must withstand a complex combination of tension, vibration, and potential shear forces. This requires specialized head designs to sit flush with the liner, advanced materials for strength, and precise engineering to resist loosening under constant dynamic stress.
