Key Features
- CA Brass Cage – One-piece machined brass cage provides excellent strength and damping against shock loads common in steel rolling
- K Tapered Bore (1:12) – Enables mounting on adapter sleeve for easier installation and removal of large bearings, plus precise clearance adjustment
- W33 Lubrication Groove – Outer ring groove and holes ensure consistent lubricant delivery, critical for high-temperature mill environments
- Extreme Load Capacity – Dynamic load rating of 5650kN and static rating of 8600kN for the most demanding rolling applications
Applications
- Wire rod mill finishing stands – high-speed continuous operation with frequent roll changes
- Bar mill heavy stands – extreme load capacity for large section rolling
- Reversing roughing mills – robust design for continuous shock loads during reversing operations
What mill applications is the 22372CAK/W33 best suited for?
The 22372CAK/W33 is specifically designed for wire rod mill finishing stands, bar mill heavy stands, and reversing roughing mills. Its CA brass cage provides excellent shock load resistance, while the K tapered bore enables easy mounting with an adapter sleeve – a key advantage for stands with frequent roll changes.
What does the K suffix mean and why choose it over the straight bore version?
The K suffix indicates a 1:12 tapered bore. This allows the bearing to be mounted on an adapter sleeve, which simplifies installation and removal of large bearings like the 22372 (443kg). It also enables precise internal clearance adjustment. For applications where mounting convenience is less critical, the straight bore version (22372CA/W33) is available.
How does the CA brass cage benefit rolling mill applications?
CA indicates a one-piece machined brass cage. In rolling mill applications, especially in reversing stands and wire rod finishing mills, the CA cage provides superior strength and shock load resistance compared to standard steel cages. It is the preferred choice for heavy-impact mill stands where cage fracture is a common failure mode.
