High Precision Angular Contact Ball Bearing for Ball Screw Support with 7921A5TYNDBLP4
NSK 7921A5TYNDBLP4 is a specific model of bearing manufactured by NSK (Nippon Seiko Kabushiki Kaisha), a Japanese precision bearing company. Here's an introduction to this bearing:
1. Model interpretation
The NSK 7921A5TYNDBLP4 is a high-precision angular contact ball bearing, which falls under the category of precision mechanical components and is primarily used in applications requiring high-speed rotation and precise positioning. Let me provide you with a detailed introduction to this bearing:
Model Breakdown:
- NSK: Manufacturer name, indicating that this bearing is produced by NSK Corporation.
- 7921A5TYNDBLP4: Model designation, broken down into several parts:
- 7921: Represents the bearing series number.
- A5: Indicates the bearing's contact angle; A5 signifies a 25-degree contact angle, which is a common angle for angular contact ball bearings.
- TYN: Denotes the bearing's design type, which may relate to features like sealing, lubrication, etc.
- DB: Indicates the bearing's arrangement type; DB signifies a back-to-back arrangement, which helps support larger radial and axial loads.
- LP4: Specifies the bearing's precision grade; LP4 corresponds to a P4 precision level, signifying a high-precision grade.
**Features and Applications:**
- **High Precision:** This bearing is designed to a high precision level, making it suitable for applications that demand precise positioning control and high-speed rotation.
- **Angular Contact Design:** The angular contact ball bearing design allows it to withstand both radial and axial loads, particularly axial loads in one direction.
- **Back-to-Back Pairing:** The back-to-back pairing arrangement enhances rigidity and load distribution, making it suitable for scenarios requiring support for multiple-direction loads.
- **Application Fields:** This type of bearing is commonly used in precision machinery, machine tools, automation equipment, semiconductor manufacturing equipment, medical devices, and other fields that require high precision and high-speed rotation.
Here's the translation of the information about the applications of angular contact bearings:
Angular contact bearings are widely used in various applications due to their special design and construction. Here are some common application areas of angular contact bearings:
1. Machine Tools: Angular contact bearings are extensively used in the machine tool industry, particularly in spindles and support components. They can withstand high-speed rotation and complex loads, ensuring precise positioning and rigidity.
2. Automotive Industry: In automotive manufacturing, angular contact bearings are commonly used in steering systems, transmissions, and engine components. They can handle complex forces and torques, providing stable motion and reliability.
3. Aerospace: Due to their high rigidity and load-carrying capacity, angular contact bearings find extensive application in the aerospace industry for aircraft engines, landing gear, and control systems.
4. Hydraulic and Pneumatic Equipment: Angular contact bearings are frequently used in rotating mechanisms of hydraulic and pneumatic equipment, such as hydraulic pumps, pneumatic motors, and compressors. They can handle high-speed rotation and significant axial loads.
5. Motors and Generators: In motor and generator applications, angular contact bearings are used to support rotor components and provide support and stability during high-speed rotation.
6. Heavy Machinery and Industrial Equipment: Angular contact bearings are also widely used in heavy machinery and industrial equipment, such as metallurgical equipment, mining machinery, and construction machinery.
These are just some common application areas of angular contact bearings. In reality, angular contact bearings can be used in other rotating systems where support and transmission of complex loads are required. Their versatility and performance make them critical components in many industrial and mechanical applications.
