Ama-roller bearings angama-cylindrical

Le khasi NU324ECJ is a specific type of cylindrical roller bearing. Here’s a breakdown of its designation and key features:

1. NU Designation:

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

2. 324:

• 3: Series designation, indicating the bearing’s dimensions and load-carrying capacity. A “3” series typically denotes a medium-heavy duty bearing.
• 24: Bore diameter in millimeters. To calculate the bore size, multiply the last two digits by 5:
  $24\times 5=120\text{mm}$.
  So, the bore diameter is 120 mm.

3. ECJ:

• EC: Stands for “Optimized Internal Design,” which typically means improved roller geometry, higher load capacity, and reduced stress distribution.
• J: Indicates the material and design of the cage (retainer). A “J” usually refers to a pressed steel cage, which is lightweight and suitable for high-speed applications.

Izici Eziyinhloko:

• Ukuthayipha: Cylindrical roller bearing (NU type).
• Ububanzi obukhulu: 120 mm.
• Design: Optimized internal design (EC) for higher load capacity and performance.
• Cage: Pressed steel cage (J).
• Izinja: Suitable for applications requiring high radial loads and axial displacement, such as in industrial machinery, amabhokisi ogiya, kanye nezinjini zikagesi.

Ubukhulu (Typical for NU324):

• Inner Diameter (d): 120 mm.
• Ububanzi obungaphandle (D): 260 mm.
• Ububanzi (B): 55 mm.

Amanothi:

• Always verify the exact dimensions and specifications from the manufacturer’s datasheet or catalog, as tolerances and designs may vary slightly between manufacturers.
• Proper lubrication and mounting are critical for optimal performance and longevity of the bearing.
