2. ベアリングの名称: 3204ATN9
- 3204: This indicates the bearing’s size and series.
- 3: 級数 (ライトデューティーまたはミディアムデューティー).
- 204: Bore diameter (20 ミリメートル) and outer diameter (47 ミリメートル).
- ある: Contact angle (typically 30° for angular contact bearings).
- TN9の: Indicates the cage material and design.
- TN: ポリアミド (ナイロン) 籠, 軽量で高速アプリケーションに適しています.
- 9: Likely refers to a specific internal design or clearance.
3. 寸法:
- 内径 (d): 20 ミリメートル
- 外径 (D): 47 ミリメートル
- 幅 (B): 14 ミリメートル (typical for this series, but confirm with manufacturer specs).
4. 負荷容量:
- Angular contact bearings are designed to handle both radial and axial loads. The exact load capacity depends on the contact angle and bearing design.
- ダイナミック定格荷重 (C): Typically in the range of 10-15 kNの (check manufacturer specs).
- 静的定格荷重 (C0): Typically around 5-10 kNの (check manufacturer specs).
5. 速度定格:
- Suitable for high-speed applications due to the polyamide cage (TN9の).
- Exact speed limits depend on lubrication and operating conditions.
6. アプリケーション:
- Commonly used in:
- Machine tool spindles.
- Pumps.
- ギアボックス.
- High-speed motors.
- Any application requiring precise axial and radial load handling.
7. 潤滑:
- Typically lubricated with grease or oil, depending on the application and speed requirements.
8. Mounting:
- Angular contact bearings are often mounted in pairs (back-to-back or face-to-face) to handle axial loads in both directions.
9. クリアランス:
- The internal clearance is typically specified by the manufacturer and depends on the application (例えば。, C2, CNの, C3の).
10. Manufacturer Variations:
- Different manufacturers may have slight variations in design, 定格荷重, and tolerances. Always refer to the specific datasheet for the exact bearing you are using.
