A290-7021-X322

Crafted by FANUC, the A290-7021-X322 shaft is an essential component designed for high-performance applications. Constructed from SCM440 steel, this shaft exhibits commendable strength and mechanical stability, reinforced through a quenching and tempering process. The precision finish of Ra 0.8 µm results in a finely ground surface that minimizes friction and wear during operation.

This component maintains a tight tolerance of ±0.02 mm, contributing to its overall reliability in motion applications. With a hardness measurement between 48 and 52 HRC, it effectively resists deformation and offers durability under load conditions. The shaft is engineered with a press-fit J2 hub, facilitating secure mounting, while the black oxide coating serves to protect against oxidation and wear.

In terms of performance, the A290-7021-X322 shaft has a minimum axial load capacity of 500 N, making it suitable for demanding operational requirements. It accommodates operating temperatures ranging from -40°C to +120°C, which allows for versatility in various environments. The mounting interface is designed as splined/flanged, enabling efficient installation.

Additionally, this shaft demonstrates excellent radial runout characteristics of less than 0.1 mm, ensuring smooth rotational motion. With a fatigue life exceeding 10 million cycles, it provides durability that meets the rigorous demands of continuous use in industrial settings.
