Key Features

  • CC Steel Cage – Two-piece stamped steel cage provides good strength-to-weight ratio, ideal for high-speed continuous rolling operations
  • W33 Lubrication Groove – Outer ring groove and holes ensure consistent lubricant delivery to the roller-raceway contact area
  • Optimized for Speed – CC cage design allows higher operating speeds compared to brass cage versions
  • High Load Capacity – Dynamic load rating of 4800kN and static rating of 9600kN for heavy-duty rolling applications
  • Cost-Effective Solution – Steel cage offers excellent value for continuous mill operations without compromising reliability

Applications

  • Four-high rolling mill backup rolls – high radial load capacity for large rolling forces
  • Hot strip mill backup positions – continuous high-speed operation with moderate shock loads
  • Large plate mill backup rolls – reliable performance under sustained heavy loads

What mill applications is the 24180CC/W33 best suited for?

The 24180CC/W33 is specifically designed for four-high rolling mill backup rolls, hot strip mill backup positions, and large plate mills. Its CC steel cage design makes it ideal for continuous, high-speed rolling operations where reliability and cost-effectiveness are key considerations.

What does the CC suffix mean and how does it compare to CA?

CC indicates a two-piece stamped steel cage. Compared to CA (one-piece machined brass cage), the CC design offers higher speed capability and a more cost-effective solution. It is the preferred choice for continuous rolling operations where shock loads are moderate and speed is a priority. For heavy shock load applications, CA brass cage is recommended.

Why is the W33 lubrication feature important for rolling mills?

W33 indicates a lubrication groove and holes in the outer ring. This is critical for rolling mill environments because it ensures consistent lubricant delivery to the roller-raceway contact area, improves heat dissipation, and extends relubrication intervals in high-temperature conditions.
