די NU 318 ECJ is a type of cylindrical roller bearing. Here’s a breakdown of its designation and key features:

1. NU Designation:

• NU indicates the type of cylindrical roller bearing. אין דעם פאַל:
  • NU: The bearing has two fixed ribs on the outer ring and no ribs on the inner ring. This design allows the inner ring and rollers to move axially relative to the outer ring, making it suitable for applications where axial displacement needs to be accommodated.

2. 318:

• This is the size designation of the bearing.
• 3: ינדיקייץ די סעריע (medium-heavy duty).
• 18: Refers to the bore diameter. פֿאַר מעטריק בערינגז, די נודניק דיאַמעטער קענען זיין קאַלקיאַלייטיד ווי:
  • נודנע דיאַמעטער (mm) = 18 × 5 = 90 mm.

3. ECJ:

• עק: Stands for “Optimized Internal Design.” This indicates that the bearing has an enhanced internal geometry, providing higher load capacity and better performance.
• J: Refers to the material and design of the cage (retainer). אין דעם פאַל, J indicates a pressed steel cage.

Key Features of NU 318 ECJ:

• טיפּ: Cylindrical roller bearing (NU type).
• נודנע דיאַמעטער: 90 mm.
• ויסווייניקסט דיאַמעטער: Approximately 190 mm (standard for NU 318 סעריע).
• ברייט: Approximately 43 mm (standard for NU 318 סעריע).
• קאַגע: Pressed steel cage (J).
• מאַסע קאַפּאַציטעט: High radial load capacity due to the EC (optimized internal design).
• Axial Displacement: Suitable for applications requiring axial displacement of the shaft relative to the housing.

אַפּפּליקאַטיאָנס:

NU-type cylindrical roller bearings are commonly used in:

• עלעקטריק מאָטאָרס.
• גירבאַקס.
• ינדוסטריאַל מאַשינערי.
• Applications where high radial loads and axial displacement are present.
