Key Features

  • K30 Tapered Bore (1:30) – Designed for mounting on adapter sleeves in large bearing applications, enabling easy installation and removal
  • CC Steel Cage – Two-piece stamped steel cage offers good speed capability and cost-effectiveness for continuous rolling
  • W33 Lubrication Groove – Outer ring groove and holes ensure consistent lubricant delivery in high-temperature environments
  • Hot Continuous Mill Design – Optimized for the demands of hot strip mill support roll positions

Applications

  • Hot strip mill support rolls – continuous rolling with moderate shock loads
  • Hot continuous rolling mills – reliable performance under sustained high-temperature operation
  • Large mill backup positions – K30 taper enables easy mounting with adapter sleeves

What mill applications is the 24072CCK30/W33 best suited for?

The 24072CCK30/W33 is specifically designed for hot strip mill support rolls and hot continuous rolling mill backup positions. Its CC steel cage and K30 tapered bore make it ideal for continuous rolling operations with moderate shock loads and high temperatures.

What does the K30 suffix mean and how does it differ from K?

K30 indicates a 1:30 tapered bore. While the standard K suffix means 1:12 taper, K30 is a different taper ratio often specified for large rolling mill bearings with specific mounting requirements. The K30 design offers distinct mounting characteristics with adapter sleeves.

What is the advantage of the CC cage in this bearing?

CC indicates a two-piece stamped steel cage. This design offers good speed capability and a cost-effective solution for continuous rolling operations. It is ideal for applications where shock loads are moderate and operating speeds are relatively high.
