22348 CCJA/W33VA405
Spherical roller bearings are designed to handle heavy loads in both axial and radial directions. They are self-aligning, allowing them to compensate for shaft deflection and misalignment with minimal impact on friction or operating temperature. This design ensures reliable performance in various types of vibrating equipment. Additionally, these bearings feature construction elements that make relubrication easy. They can also be integrated into modular systems with compatible housings, adapter sleeves, and lock nuts.
Designed for extra-large vibrating screens and heavy mining machines.
VA405 cage improves heat resistance and vibration endurance.
Exceptional load capacity supports continuous shock and impact.
W33 lubrication groove ensures better cooling and reliability.
