719/6C Bearing Product Overview & Core Advantages
The 719/6C is a miniature precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Engineered with a 15° contact angle, this bearing efficiently handles combined loads (simultaneous radial and axial loads) while maintaining superior running precision. Its compact dimensions (6 mm bore, 15 mm OD, 5 mm width) and availability in high-precision ABEC P5/P4 grades make it an ideal solution for high-reliability, space-constrained applications requiring minimal vibration and noise.
719/6C Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 719 | Series designation for miniature, high-precision angular contact ball bearings. |
| 6 | Nominal bore diameter in millimeters (6 mm). |
| C | Denotes a 15° contact angle, optimized for high-speed operation and high rigidity. |
Available Options: This bearing is offered in both Sealed (for contamination protection) and Open (for maximum speed and custom lubrication) versions. It is also available with preload and is Universal Matchable (SU), allowing for precise axial play adjustment when mounted in pairs.
719/6C Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The angular contact design and availability in ABEC P5/P4 precision classes provide exceptional rotational accuracy and stiffness, minimizing deflection under load.
- Superior Load Capacity: The 15° contact angle enables the bearing to support significant combined radial and axial loads simultaneously.
- Exceptional High-Speed Performance: With a grease limited speed of 80,000 r/min and an oil limited speed of 85,000 r/min, this bearing is engineered for ultra-high-speed spindles. Options for lightweight Nylon or Phenolic cages further enhance dynamic performance.
- Material & Lubrication Versatility: Available with Steel or Ceramic balls, allowing for optimization based on application requirements for speed, stiffness, and corrosion resistance. The lubricated design ensures immediate operation and long service life.
- Lightweight Design: Weighing only 0.0038 kg, it contributes to reduced rotational inertia in high-acceleration applications.
719/6C Bearing Typical Application Areas
- High-Speed Spindles: PCB drilling spindles, dental handpieces, and small precision machining centers.
- Precision Instruments: Optical scanners, encoder systems, and laboratory equipment.
- Robotics & Automation: Small robotic joints, servo motors, and precision gearboxes.
