Component Specifications

Definition
The Wobbler End is a specialized mechanical component attached to work rolls in rolling mills, designed to precisely control the lateral movement and oscillation of rolls during metal forming operations. It ensures uniform material distribution, prevents edge defects, and maintains consistent thickness across the rolled product through controlled wobbling motion.
Working Principle
Operates by converting rotational force from the drive system into controlled lateral oscillation of the work roll. This wobbling motion distributes wear evenly across the roll surface, prevents material buildup, and ensures consistent pressure distribution during metal deformation processes.
Materials
High-grade alloy steel (typically AISI 4140 or equivalent), heat-treated to HRC 45-50 for wear resistance. Surface may be coated with tungsten carbide or ceramic for enhanced durability in high-temperature applications.
Technical Parameters
  • Load Capacity 50-200 kN
  • Diameter Range 150-500 mm
  • Connection Type Tapered or splined shaft interface
  • Operating Temperature Up to 400°C
  • Oscillation Frequency 5-30 Hz
  • Maximum Lateral Displacement ±2-10 mm
Standards
ISO 9001:2015, DIN 1543, ASTM A29
