Precision Guide Wheel Shaft Assembly Hardened 40Cr / 20CrMnTi Steel H6 Tolerance

Product Profile: Precision Guide Wheel Shaft Assembly

A core transmission component engineered to support guide wheels, transmit torque, and ensure accurate motion trajectories in mechanical systems. Integrates seamlessly with bearings and seals to deliver optimal strength, wear resistance, and assembly precision.

Key Features:
✔ Dual Material Options – 40Cr (quenched & tempered, HB220-260) or 20CrMnTi (carburized, surface hardness HRC58-62)
✔ Precision Tolerance – Shaft diameter controlled to h6 standard (e.g., φ50h6: -0.016~0mm)
✔ Welded Robustness – Base plate and shaft integrally welded for structural integrity
✔ Wear-Resistant Surface – Hardened treatments extend service life under high friction

Technical Specifications:

• Shaft Materials: 40Cr or 20CrMnTi

• Hardness Options:

  • 40Cr: Bulk hardness HB220-260
