Nke QJ206MA is a specific type of Angular Contact Ball Bearing. Nke a bụ ndakpọ atụmatụ ya na nkọwapụta ya:
1. Type of Bearing:
- Angular Contact Ball Bearing: Designed to handle combined radial and axial loads, these bearings have contact angles that enable them to support higher axial loads compared to deep groove ball bearings. They are typically used in pairs or sets to accommodate loads in both directions.
2. Bearing Designation:
- QJ206MA:
- QJ: Indicates a four-point contact ball bearing, which is a type of angular contact bearing. It can handle axial loads in both directions and radial loads simultaneously.
- 206: Specifies the size of the bearing. Nke “2” indicates a light series, and “06” refers to the bore diameter (30 mm).
- MA: Denotes the material or design specifics. “MA” typically means the bearing has a brass cage (retainer) and is designed for high-speed applications.
3. Akụkụ:
- Obere dayameta (d): 30 mm
- Dayameta dị n'èzí (D): 62 mm
- Obosara (B): 16 mm
4. Ngosipụta ibu:
- Ngosi ibu dị ike (C): The maximum load the bearing can handle while rotating.
- Ngosi Ibu Ibu Static (C0): The maximum load the bearing can handle while stationary.
(Exact load ratings depend on the manufacturer and should be verified from the product datasheet.)
5. Ngwa:
- Angular contact ball bearings like the QJ206MA are commonly used in:
- Machine tool spindles
- Pumps
- Igbe igbe
- High-speed applications
- Applications requiring precise axial and radial load handling
6. Cage Material:
- Nke “MA” suffix indicates a brass cage, which is durable and suitable for high-speed operations.
7. Lubrication and Sealing:
- Typically, these bearings are lubricated with grease or oil. Sealing options (eg, rubber seals or metal shields) may vary depending on the application.
8. Mounting:
- Angular contact bearings are often mounted in pairs (back-to-back, face-to-face, or tandem) to handle axial loads in both directions.
If you need more specific details (eg, load ratings, tolerances, or exact dimensions), refer to the manufacturer’s datasheet or product catalog. Popular manufacturers of such bearings include SKF, NSK, FAG, and Timken.
