Carburized Synchronizer Cone for Heavy Duty Truck

Designed to withstand the rigors of long-haul transportation and heavy-load operations, our carburized steel synchronizer cones provide reliable synchronization between rotating gears, reducing wear and extending transmission service life. With a monthly production capacity of 5,000 pieces, we can consistently meet the demands of fleet operators, repair shops, and parts distributors worldwide. All our products are manufactured in our state-of-the-art facilities in Jinan, Shandong, China, and undergo rigorous quality testing to ensure compliance with international standards.

Core Advantages

Superior Carburizing Technology

Our heavy-duty truck synchronizer cones feature advanced carburizing and carbonitriding surface treatment, achieving a surface hardness of 58-62HRC with a uniform infiltration layer depth of 0.8-1.2mm. This process creates a hard, wear-resistant surface while maintaining a tough, ductile core that resists impact and fatigue failure.

Precision Machining Excellence

Each carburized synchronizer cone is manufactured to ISO 6-8 level tooth profile accuracy with a tooth surface roughness Ra ≤ 1.6μm. We strictly control heat treatment deformation, ensuring tooth alignment error ≤ 0.02mm for smooth meshing, low noise operation, and optimal transmission efficiency.

Extended Service Life

In addition to carburizing, we apply shot peening treatment to introduce residual compressive stress, improving fatigue life by 20-30%. Our use of high-grade steel raw materials ensures that our synchronizer cones for dump trucks outperform aftermarket alternatives in durability and reliability.

Technical Specifications

Manufacturing & Quality Control

Our manufacturing process follows a strict multi-stage workflow: forging → rough machining → heat treatment → precision machining → surface treatment. We combine gear hobbing with shaving and grinding techniques to achieve the highest precision standards.

We maintain comprehensive quality control systems certified to ISO 9001:2015. Every carburized synchronizer cone undergoes rigorous testing, including metallographic inspection, micro-Vickers hardness testing, and dimensional verification. Our in-house testing facilities ensure that all products meet or exceed OEM specifications before shipment. We provide pre-production samples for approval and conduct final inspections on every batch to guarantee consistent quality.
