🎯 Category Overview

NU1000 EM series are single-row cylindrical roller bearings featuring EM-grade machined brass cages, engineered for high rigidity, high-speed stability and heavy radial load capacity. Equipped with a double-flanged outer ring and a flangeless inner ring, they permit free axial displacement of the shaft to compensate for thermal expansion, making them ideal for non-locating positions in heavy-duty transmission systems.

⚙️ Core Advantages

Brass Cage (EM): Enhanced strength and heat dissipation, suitable for continuous high-speed operation.
Non-Locating Design: Axial float design compensates for shaft thermal expansion, reducing stress on the system.
High Load Capacity: Optimized roller geometry delivers superior radial load resistance and rigidity.
Precision Manufacturing: Tight tolerance control ensures low noise, low vibration and long service life.
Global Interchangeability: Standard dimensions ensure direct replacement of equivalent international brands.

🛠️ Typical Applications

Widely used in large-scale industrial motors, heavy-duty reducers, mining equipment, large-scale fans, blowers, compressors, marine machinery and other high-power, high-load rotating equipment requiring stable radial support

Category Overview

Cylindrical Roller Bearings are radial rolling bearings with cylindrical rolling elements that make line contact with raceways. They feature high radial load capacity, high rigidity, high-speed capability, and low friction.Most types can accommodate axial displacement between shaft and housing, and some structures allow carrying axial loads. They are widely used in motors, gearboxes, pumps, compressors, machine tools and other heavy‑duty rotating equipment.
