Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
Motor-driven shaft with impellers for controlled agitation in crystallization vessels.
A compression-type crusher that reduces material size by squeezing it between a gyrating mantle and a stationary concave bowl liner.
The eccentric assembly is a critical rotating component in a cone crusher that converts the rotational motion from the drive system into the gyratory crushing motion.

Critical considerations include torsional strength to handle torque loads, bending stiffness to minimize deflection, corrosion resistance for process fluids, dynamic balancing to reduce vibration, and proper sealing integration to prevent leakage.
Stainless steel (316L) offers excellent corrosion resistance for chemical and food processing, while alloy steels provide higher strength for high-torque applications. Material choice impacts fatigue life, maintenance frequency, and compatibility with process fluids.
