Custom Carburized 17CrNiMo6 Steel Roller Shafts

Engineered for Maximum Wear Resistance and Fatigue Life in Demanding Applications

In the extreme environment of a steel rolling mill or a heavy-duty gearbox, component failure is not an option. Roller shafts, pinions, and spindles are subjected to immense contact stress, shock loads, and abrasive wear. Standard steels cannot survive these conditions. For these critical applications, 17CrNiMo6 (18CrNiMo7-6) is the material of choice, and Yile Machinery is your expert manufacturing partner.

We specialize in the precision machining and advanced heat treatment of 17CrNiMo6 roller shafts. We deliver components with a superior hardened case and a tough core, engineered to provide maximum service life in the world's most demanding industrial environments.

Key Features & Benefits:

• Genuine 17CrNiMo6 / 18CrNiMo7-6 Steel: We start with certified, high-quality forged blanks of this nickel-chromium-molybdenum alloy steel. The composition is engineered for exceptional hardenability and core strength, providing the foundation for superior performance.

• Expert Case Hardening (Carburizing): This is the most critical step. The machined shaft undergoes a controlled carburizing, quenching, and tempering process. This creates:

• A High-Hardness Surface Case (58-62 HRC): Provides exceptional resistance to wear, spalling, and contact fatigue.

• A Tough, Ductile Core: Absorbs shock loads and prevents brittle fracture, ensuring the shaft's overall integrity under extreme torque and bending forces.

• Precision Grinding: After heat treatment, all critical surfaces, especially bearing journals and roll body diameters, are precision ground to exacting tolerances. This ensures a perfect fit, minimizes vibration, and extends the life of both the shaft and its mating components.

• Guaranteed Internal Integrity: All forgings undergo 100% Ultrasonic Testing (UT) to ensure they are free from internal defects. We provide full material certification and heat treatment reports with every shaft.
