The surface area of the Input Shaft is induction hardened, resulting in a surface hardness of HRC50~55, which enhances wear resistance and durability. Its core strength measures a minimum of 500 N\/mm², ensuring it can withstand high torque loads during operation. The part dimensions are Ø62 mm in outer diameter and 89 mm in length, with a manufacturing tolerance of 20 microns on the outer diameter and 13 microns on the inner diameter, guaranteeing precise fitment. The Input Shaft's construction from high-grade materials and advanced heat treatment processes make it suitable for demanding automotive, industrial, and heavy machinery applications. It is ideal for use in transmission systems requiring durability and high core strength, especially in situations where precision machining and surface hardness are critical for long-lasting performance. The product does not include additional components and ships as a single, ready-to-install shaft.
