Richiesta

Le NU318 EM è un tipo di cuscinetto a rulli cilindrici. Here’s a breakdown of its specifications and features:

1. Tipo di cuscinetto:

NU: This indicates the type of cylindrical roller bearing. NU-type bearings have two fixed ribs on the outer ring and no ribs on the inner ring, allowing the inner ring to move axially relative to the outer ring. This design is suitable for applications where axial displacement needs to be accommodated.

2. Dimensioni:

Le 318 in the bearing code refers to its size. The dimensions for NU318 are:
- Diametro foro (d): 90 millimetro
- Diametro esterno (D): 190 millimetro
- Larghezza (B): 43 millimetro

3. Suffix:

EM: This suffix typically indicates the bearing’s internal design and cage material. In this case:
- E: Optimized internal design for higher load capacity.
- M: Indicates that the cage is made of machined brass (solid brass cage), which is suitable for high-speed applications and provides better lubrication retention.

4. Portata:

NU318 EM bearings are designed to handle high radial loads due to their cylindrical roller design. They are not suitable for axial loads because of the NU design (no ribs on the inner ring).

5. Applicazioni:

NU-type cylindrical roller bearings are commonly used in applications where high radial loads and axial displacement are present, such as:
- Motori elettrici
- Riduttori
- Industrial machinery
- Pompe
- Paper manufacturing equipment

6. Lubrication:

Proper lubrication is essential for optimal performance. Grease or oil lubrication can be used depending on the application and operating conditions.

7. Mounting and Maintenance:

NU318 EM bearings require precise mounting to ensure proper alignment and load distribution. Regular maintenance, including lubrication and inspection, is necessary to extend the bearing’s lifespan.

Se hai bisogno di ulteriori dettagli, such as dynamic/static load ratings or specific operating conditions, consult the manufacturer’s datasheet or technical documentation.
