The side guard plate of a jaw crusher, also known as the cheek plate or side plate, is a critical wear-resistant component installed on both sides of the crushing chamber, positioned between the fixed jaw plate and the movable jaw plate. Its primary function is to protect the side walls of the frame from direct impact and abrasion caused by the material, thereby extending the overall service life of the machine.
Materials and Performance Characteristics
Mainstream Materials: These plates are typically manufactured from high manganese steel (e.g., ZGMn13) or high chromium cast iron. High manganese steel undergoes "work hardening" under severe impact, becoming harder as it wears while maintaining excellent core toughness and high impact resistance. High chromium cast iron, on the other hand, offers higher hardness (HRC 55-63) and superior wear resistance, making it ideal for highly abrasive materials.
Structural Design: As shown in the figure, the side guard plate is a rectangular block with a flat surface. Some feature mounting holes or positioning structures for easy bolt fastening. The thickness typically ranges from 20 to 50 mm, depending on the crusher model and operating conditions.
Replacement Criteria and Maintenance Recommendations
Wear Assessment: The side guard plate must be replaced when the wear reaches 25% (one-quarter) of its original thickness. Continued use can lead to the frame body being worn through, resulting in a dramatic increase in maintenance costs.
Inspection Points: Regularly inspect the surface for severe pitting, cracks, or localized thinning. An increase in dust leakage or a coarser product size may also indicate excessive wear of the side guard plate.
Installation Precautions: During replacement, clean the mounting surface thoroughly to ensure there is no residual material or rust. Bolts must be tightened in a crisscross (diagonal) pattern to prevent uneven stress distribution, which could lead to deformation or loosening.

The mainframe is designed for continuous heavy-duty operation. Wear parts such as jaw plates, liners and blow bars are made of high-manganese steel or alloy materials, and their service life depends on the material hardness and working hours.
Every machine goes through material inspection, machining inspection, assembly and a full no-load test run before shipment. Inspection records and test videos are provided to customers.
Warmly welcome. You can visit our manufacturing base in person, and remote video inspection is also available for customers from overseas.
Yes. Package orders of a full line or multiple machines usually receive a more favorable price and priority in the production schedule.
Large mainframes are shipped by sea in containers or bulk vessels; smaller machines and spare parts go by container, air freight or international express, with full packaging for moisture and rust protection.
