دی NU328 EM is a type of cylindrical roller bearing. Here’s a breakdown of its specifications and features:

NU328 EM Bearing Details

1. Type: Cylindrical Roller Bearing
2. Series: NU328
3. Designation: EM
4. Inner Diameter (d): 140 ملی میٹر
5. Outer Diameter (D): 300 ملی میٹر
6. چوڑائی (B): 62 ملی میٹر
7. Dynamic Load Rating (C): Typically around 735 kN (exact value depends on the manufacturer)
8. Static Load Rating (C₀): Typically around 780 kN (exact value depends on the manufacturer)
9. Cage Material: EM indicates a machined brass cage (solid brass cage)
10. Lubrication: Usually requires grease or oil lubrication, depending on the application.

Key Features

• NU Design: دی “NU NU” designation means the bearing has two flanges on the outer ring and no flanges on the inner ring. This allows the inner ring to move axially, making it suitable for applications with axial displacement.
• High Load Capacity: Cylindrical roller bearings are designed to handle high radial loads.
• EM Cage: The machined brass cage (EM) provides high strength, durability, and stability, especially in high-speed or high-temperature applications.
• Precision: Suitable for precision applications due to its robust design and high load-carrying capacity.

Applications

NU328 EM bearings are commonly used in:

• Industrial gearboxes
• Electric motors
• Pumps
• Compressors
• Heavy machinery
• Wind turbines

Advantages

• High radial load capacity
• Suitable for high-speed operations
• Durable brass cage for enhanced performance
• Accommodates axial displacement of the shaft
