O NU334 EM is a type of cylindrical roller bearing. Here’s a breakdown of its designation and key features:

1. NU334 EM Designation:

NU: Indicates the bearing type. “NU” means it is a cylindrical roller bearing with two fixed ribs on the outer ring and no ribs on the inner ring. This design allows the inner ring to move axially relative to the outer ring, making it suitable for applications with axial displacement.
33: Refers to the series. O “33” series indicates a heavy-duty design with a larger cross-section and higher load-carrying capacity compared to lighter series.
4: Represents the bore size. The bore diameter can be calculated by multiplying this number by 5 (for metric bearings). So, 4 × 5 = 20 mm bore diameter.
EM: Indicates the internal design and cage material. “EM” typically refers to a machined brass cage (solid brass cage), which is robust and suitable for high-speed and high-temperature applications.

2. Características clave:

Tipo: Cylindrical roller bearing (NU type).
Capacidade de carga: High radial load capacity, but not designed for axial loads (except for small axial displacements).
Gaiola: Machined brass cage (EM) for durability and high-speed performance.
Aplicacións: Suitable for applications with high radial loads and where axial displacement of the shaft is expected, such as in gearboxes, electric motors, and industrial machinery.

3. Dimensións (Typical for NU334 EM):

Diámetro de ánima (d): 170 mm
Diámetro exterior (D): 360 mm
Anchura (B): 72 mm
Clasificación de carga dinámica (C): ~1,100 kN (aprox., depending on manufacturer)
Clasificación de carga estática (C0): ~1,400 kN (aprox., depending on manufacturer)

4. Aplicacións:

Maquinaria pesada.
Caixas de cambios.
Motores eléctricos.
Industrial pumps.
Steel mills.

5. Notes:

Always verify the exact dimensions and load ratings from the manufacturer’s datasheet, as these can vary slightly between brands.
Proper lubrication and mounting are critical for optimal performance and longevity of the bearing.
