Manufactured by ZKL, a renowned European bearing producer, this bearing is engineered to ensure reliability, durability, and smooth operation under demanding conditions.
This bearing type belongs to the NU series, characterized by its ability to accommodate heavy radial loads and moderate axial displacement in both directions. The design features a cylindrical roller and an outer ring with two ribs, allowing the inner ring to move axially, which makes it ideal for applications where thermal expansion or shaft deflection occurs.
Key Features and Benefits
- Robust Construction: Made from high-quality steel, the NU 2219 ZKL ensures long service life and resistance to wear and fatigue.
- Axial Displacement Capability: The NU design allows the inner ring to move axially, accommodating shaft expansion and contraction without compromising performance.
- High Radial Load Capacity: Suitable for heavy radial loads, making it ideal for motors, gearboxes, and industrial machinery.
- Precision and Stability: Manufactured with tight tolerances to provide smooth rotation and reduce vibration.
- Sealing: The "Z" designation indicates the bearing has a single metal shield on one side, protecting against contamination while allowing for reduced friction.
