LTZC precision gear parts

LTZC gears, gear shafts, and gear rings are made of special high-strength alloy steel and undergo precision carburizing, quenching, and multi-stage heat treatment processes. The gear surface hardness consistently reaches HRC 58–62, and the gear profile accuracy reaches DIN 5–6 grade, ensuring long-term stable operation under high impact and high load conditions. Relying on LTZC's own large-scale production plant, the entire process from raw material inspection, forging, CNC machining, heat treatment to precision gear grinding is completed independently by the LTZC team, forming a complete closed-loop manufacturing system that ensures the controllability and consistency of each process. Its products have ultimately passed international certifications such as ISO9001, 14001, 45001, CCS, BV, and ABS.

LTZC Precision Gear Advantages

Made with high-purity alloy steel (42CrMo / 20CrMnTi), the tooth surfaces undergo carburizing, quenching, and precision grinding. LTZC precision gears are ground using CNC precision equipment to ensure tooth surface accuracy, with a surface hardness of HRC58–62 and an effective hardened layer depth ≥1.2–2.5 mm. Gear profile accuracy reaches DIN 5–6 grade / ISO 5 grade, ensuring smooth meshing and low transmission noise.

LTZC Gear Shaft Advantages

Made with high-strength quenched and tempered alloy steel (42CrMo, 40CrNiMo), the journal area undergoes high-frequency quenching, achieving a surface hardness of HRC50–55, significantly improving wear resistance. Coaxiality control ≤0.01 mm, runout accuracy reaches micron-level control standards, achieving high-precision, high-torque, long-term stable output. Suitable for rotary drives, shaft gear motors, gearboxes, and other equipment.

LTZC Gear Ring Advantages

LTZC specializes in manufacturing large-size gear rings, with a maximum outer diameter of 12,000 mm, meeting the needs of heavy-duty slew equipment. The gear rings utilize both integral forging and split-type structures, with carburized and quenched tooth surfaces to a hardness of HRC58–62, and strengthened tooth roots, providing strong resistance to tooth breakage. LTZC bearings offer customized solutions for various structures, including internal gears, external gears, spur gears, and helical gears, to adapt to different transmission systems.
