The KOYO 7203B is an angular contact ball bearing. Angular contact bearings are designed to accommodate combined loads (both radial and axial) and are commonly used in applications where high precision and rigidity are required. Here’s a breakdown of the key details:
KOYO 7203B Specifications:
- Type: Vinkelkontakt kugleleje
- Series: 7203B (the “B” indicates a specific contact angle, typically 40°)
- Dimensioner:
- Inner Diameter (d): 17 Mm
- Outer Diameter (D): 40 Mm
- Bredde (B): 12 Mm
- Contact Angle: Likely 40° (common for “B” series)
- Material: Typically made of high-quality steel or other materials depending on the application.
- Cage: Usually made of steel, brass, or polyamide (depending on the variant).
Key Features:
- Combined Load Capacity: Can handle both radial and axial loads simultaneously.
- High Precision: Suitable for applications requiring high rotational accuracy.
- Rigidity: Provides good stiffness, making it ideal for machine tools, gearboxes, and other precision machinery.
- Speed: Capable of operating at high speeds.
Applications:
- Machine tool spindles
- Gearkasser
- Pumps
- Automotive components
- Robotics
- Aerospace systems
Mounting:
Angular contact bearings are often mounted in pairs (back-to-back or face-to-face) to handle axial loads in both directions and to provide better rigidity.
