30mm AISI 4140 1.7225 Alloy Steel Forged Shaft Roller Precision Machined Industrial Shafting
This high-performance shaft roller is made from AISI 4140 (1.7225) alloy steel, known for its superior strength, toughness, and wear resistance. The 30 mm diameter shaft is precision-forged to enhance grain structure and durability under heavy loads. It is machined to tight tolerances for smooth operation in machinery, automotive systems, and power-transmission applications. After heat treatment, AISI 4140 achieves hardness levels of HRC 28–32 with excellent fatigue resistance. Designed for high-stress environments, this shaft roller ensures reliability in gearboxes, conveyors, and rotating equipment. Custom lengths and surface finishes (ground, turned, or coated) are available.
Key Features:
• High tensile strength (≥850 MPa)
• Excellent wear and impact resistance
• Precision-ground for smooth fitment
• Compatible with bearings and couplings
