619/9 Bearing Product Overview & Core Advantages
The 619/9 is a precision miniature deep groove ball bearing designed for applications demanding high rotational accuracy and reliable performance in compact spaces. As a single row open bearing with a P6 tolerance class, it offers exceptional dimensional stability and running accuracy. Its fundamental design enables it to primarily accommodate radial loads, making it an ideal component for high-speed, low-noise operations where space is at a premium.
619/9 Bearing Model Code Explained, Specifications & Naming Convention
The model designation 619/9 can be broken down as follows:
- 619: Series code for extra-small, thin-section deep groove ball bearings.
- /9: Indicates a bore diameter of 9 mm.
- Seal Type: Open - Allows for higher limiting speeds and is suitable for applications where external sealing is provided.
- Tolerance Class: P6 - Denotes a high-precision bearing with tighter dimensional and running accuracy tolerances than standard grades.
- Radial Internal Clearance: CN - Standard (normal) clearance group for general applications.
- Lubrication: None - The bearing is supplied without grease, offering flexibility for the user to apply a specialized lubricant suited to their specific operating conditions.
619/9 Bearing Structural Features & Performance Benefits
- High Precision and Stability: Manufactured to a P6 tolerance class with a stainless steel cage, this bearing ensures minimal vibration and consistent performance, which is critical for sensitive instrumentation.
- Compact and Lightweight Design: With dimensions of 9x20x6 mm and a weight of only 0.0074 kg, it is engineered for applications where minimizing size and mass is essential.
- Superior Material Construction: The use of chrome steel for rings and balls provides excellent wear resistance and durability, contributing to a long operational lifespan under radial dynamic loads up to 526 lbf.
- High-Speed Capability: The open design and precision construction enable a high limiting speed of 50,000 rpm, making it suitable for demanding high-speed applications.
619/9 Bearing Typical Application Areas
This miniature deep groove ball bearing is ideally suited for:
- Precision Instruments: Optical encoders, measuring devices, and medical instruments.
- Small Electric Motors: High-speed spindles in drones, small fans, and servo motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Joints and guides in small robotic arms and linear motion systems.
