Built for demanding operating conditions, our replacement jaw plates for Terex Pegson jaw crushers deliver strong wear resistance and consistent crushing performance in aggregate and mining applications. These essential jaw crusher parts sit at the heart of the crushing chamber, influencing daily productivity, output gradation, and overall operating efficiency. When processing abrasive materials, the crushing chamber must withstand constant stress to keep the plant productive. Our heavy-duty wear parts are carefully cast to handle high mechanical loads, helping operators reduce unexpected maintenance stops.
Enhanced Throughput: Optimized crushing chamber geometry supports steady material flow and reduces blockages.
Extended Campaign Life: Superior metallurgical properties reduce the frequency of wear part changeouts.
Energy Efficiency: Precise nip angles help lower crusher motor power consumption under heavy loads.
The crushing chamber relies on two main wear components: the stationary fixed jaw plates and the moving swing jaw plates. As the swing jaw moves back and forth under heavy force, it compresses and fractures incoming material against the fixed jaw. The material breaks into smaller pieces until it can pass through the discharge opening. Crushing hard rock creates constant impact and severe abrasion, so these jaw plates need durable materials and precise manufacturing. Our manganese steel castings provide the structural strength needed to withstand prolonged rock-on-metal friction over thousands of operating hours.
Our jaw plates are designed for Terex Pegson models, including the widely used XA400 and XR400, which serve demanding quarrying and recycling operations. We follow 100% of OEM dimensions, original drawings, and specified tolerances to ensure accurate fitment and reliable performance from the start. This precision machining gives maintenance crews a direct replacement fit, making installation easier and reducing the need for dangerous on-site modifications. Faster, more straightforward installation also helps cut costly maintenance downtime.

Our jaw plates are cast from premium-grade manganese steel, which provides strong resistance to heavy impact and severe abrasion. We offer several material configurations, including Mn13Cr2, Mn18Cr2, and Mn22Cr2, so procurement teams can choose the metallurgical composition that suits their rock hardness requirements. Under intense crushing loads, austenitic manganese steel rapidly work-hardens. Its outer surface becomes significantly harder, helping resist gouging and scratching, while the inner core remains ductile enough to absorb heavy shock loads without fracturing.
We also use industry-leading resin sand and lost foam casting technologies. These processes help create a dense internal casting structure and a smooth exterior with fewer sand inclusions or areas of porosity. Combined with our specialized heat treatment protocols, these manufacturing methods extend jaw plate service life by 20% to 30% compared to standard aftermarket alternatives. The result is a measurable reduction in operating expenses.
Different tooth patterns are available for a range of feed materials and crushing applications. Deep quarry tooth profiles, for example, provide a strong grip on large, slippery rocks. This helps prevent material boil and maintain a positive bite during the initial crushing phase. Fine tooth patterns, by contrast, help produce smaller, more uniform output sizes while improving operational efficiency and reducing recirculation load.
We also provide comprehensive OEM and ODM engineering support beyond standard profiles. Our technical team can handle complex customizations, including precise on-site mapping and the design of ultra-heavy-duty thickened tooth profiles for particularly demanding environments. From highly abrasive river gravel to sticky demolition debris, we can engineer the tooth profile geometry needed to maximize your plant's daily yield.
Quality control is central to our production process. We monitor every stage, from raw material selection and chemical composition analysis to final machining and dispatch inspection, to maintain consistent product quality. Our full-process quality monitoring system is designed to achieve zero defects upon delivery and help protect equipment against premature failures.
Dimensional Verification: Laser scanning and manual gauging to ensure perfect OEM alignment.
Hardness & Metallographic Analysis: Verifying the exact austenitic structure required for optimal work-hardening capabilities.
Non-Destructive Testing (NDT): Using penetrant testing (PT) to detect microscopic surface fissures before shipping.
Destructive Testing: Periodic batch testing to confirm ultimate tensile strength and impact toughness under extreme stress.
Our rugged jaw crusher parts serve demanding environments, including limestone quarries, hard granite mines, construction waste recycling plants, and large-scale aggregate production facilities.

Customers worldwide rely on our Terex Pegson jaw plates for dependable crushing performance and uninterrupted operations.
Engineered for maximum endurance, our replacement jaw plates for Terex Pegson jaw crushers are manufactured to deliver superior wear resistance and consistent crushing performance in the most demanding aggregate and mining applications. These essential jaw crusher parts play a critical role in the heart of the crushing chamber, directly affecting daily productivity, output gradation, and overall operational efficiency. When handling abrasive materials, the structural integrity of the crushing chamber determines the profitability of the entire plant. Our heavy-duty wear parts are meticulously cast to ensure they withstand immense mechanical stress, providing operators with a reliable solution that minimizes unexpected maintenance stops.
Enhanced Throughput: Optimized crushing chamber geometry promotes steady material flow and reduces blockages.
Extended Campaign Life: Superior metallurgical properties reduce the frequency of wear part changeouts.
Energy Efficiency: Precise nip angles help lower the power consumption of the crusher motor during heavy loads.
The crushing chamber consists of two main wear components functioning in tandem: the stationary fixed jaw plates and the articulating swing jaw plates. As the heavy swing jaw moves back and forth with tremendous force, raw material is continuously compressed, fractured, and ground between the two thick metal plates until it breaks into smaller, manageable pieces that can pass through the discharge opening. Due to the constant, deafening impact and severe abrasion generated by crushing hard rock, these jaw plates require exceptionally durable materials and highly precise manufacturing techniques. The dense, cool touch of our freshly cast manganese steel is a testament to the heavy-duty structural integrity required to survive thousands of hours of relentless rock-on-metal friction.
Our jaw plates are specifically designed to match Terex Pegson models, including the widely utilized XA400, XR400, and other popular machines heavily relied upon in heavy quarry and recycling operations. By strictly following 100% of the OEM dimensions, original drawings, and exact tolerance specifications, we ensure accurate fitment and reliable performance right out of the box. This dedication to precision machining means maintenance crews will experience a perfect drop-in fit, significantly reducing installation difficulty, eliminating the need for dangerous on-site modifications, and cutting down costly downtime maintenance hours.
