Sitä Angular Contact Ball Bearing 3204ATN9 on erityinen laakerityyppi, joka on suunniteltu käsittelemään yhdistettyjä säteittäisiä ja aksiaalisia kuormia. Here’s a breakdown of its key features and specifications:
1. Tyyppi: Angular Contact Ball Bearing
- Angular contact bearings are designed to support combined loads (both radial and axial) and are typically used in applications where high precision and rigidity are required.
2. Bearing Designation: 3204ATN9
- 3204: This indicates the bearing’s size and series.
- 3: Series (light or medium duty).
- 204: Bore diameter (20 mm) and outer diameter (47 mm).
- A: Contact angle (typically 30° for angular contact bearings).
- TN9: Indicates the cage material and design.
- TN: Polyamide (nylon) häkki, which is lightweight and suitable for high-speed applications.
- 9: Likely refers to a specific internal design or clearance.
3. Mitat:
- Reiän halkaisija (d): 20 mm
- Ulkohalkaisija (D): 47 mm
- Leveys (B): 14 mm (typical for this series, but confirm with manufacturer specs).
4. Load Capacity:
- Angular contact bearings are designed to handle both radial and axial loads. The exact load capacity depends on the contact angle and bearing design.
- Dynaaminen kuormitusluokitus (C): Typically in the range of 10-15 Kn (Tarkista valmistajan tekniset tiedot).
- Staattinen kuormitus (C0): Typically around 5-10 Kn (Tarkista valmistajan tekniset tiedot).
5. Speed Rating:
- Suitable for high-speed applications due to the polyamide cage (TN9).
- Exact speed limits depend on lubrication and operating conditions.
6. Sovelluksia:
- Commonly used in:
- Machine tool spindles.
- Pumps.
- Vaihteistot.
- High-speed motors.
- Any application requiring precise axial and radial load handling.
7. Voitelu:
- Typically lubricated with grease or oil, depending on the application and speed requirements.
8. Hela:
- Angular contact bearings are often mounted in pairs (back-to-back or face-to-face) to handle axial loads in both directions.
9. Lupa:
- The internal clearance is typically specified by the manufacturer and depends on the application (esim., C2, CN, C3).
10. Manufacturer Variations:
- Different manufacturers may have slight variations in design, load ratings, and tolerances. Always refer to the specific datasheet for the exact bearing you are using.
