672zz Bearing Product Overview & Core Advantages
The 672zz is a metric single row deep groove ball bearing designed for high-performance applications requiring compact dimensions and reliable operation. This shielded bearing excels in handling radial loads and is engineered for smooth, low-noise, and low-vibration performance. Its compact design, with a 2mm bore and 4mm outside diameter, makes it ideal for space-constrained assemblies. Manufactured to ABEC1 precision tolerances, it offers a dependable balance of performance and value for a wide range of industrial and precision instruments.
672zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 67 | Series designation, indicating a very small cross-section for its bore diameter. |
| 2 | Bore diameter code. "2" represents a 2mm bore. |
| zz | Signifies double-shielded construction (one shield on each side). The "z" suffix denotes a non-contact, pressed steel shield that protects against contamination while minimizing friction. |
672zz Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The deep groove raceway and single-row design are engineered to efficiently support significant radial loads, making it a versatile choice for various rotary applications.
Enhanced Contamination Protection: The double-shielded (zz) design features non-contact shields on both sides, effectively sealing the bearing against dust and debris without significantly increasing rotational torque, contributing to a longer service life.
Precision and Smooth Operation: Built to ABEC1 tolerance class with a stainless steel cage, this bearing ensures consistent running accuracy and smooth rotation, which is critical for reducing vibration and noise in sensitive equipment.
High-Speed Capability: With a limiting speed of 98,000 rpm, it is suitable for high-speed spindles and rotors. The optimized internal geometry and cage design contribute to stable performance at elevated rotational speeds.
672zz Bearing Typical Application Areas
- Small Precision Motors: Ideal for stepper motors, DC micromotors, and spindle motors in consumer electronics and medical devices.
- Instrumentation and Gauges: Used in sensitive measuring instruments, optical encoders, and laboratory equipment where low noise and high precision are paramount.
- Office Automation Equipment: Critical component in printers, scanners, and small fans.
- Robotics and Automation: Suitable for joints, guides, and small actuators in compact robotic systems.
- Consumer Electronics: Found in computer hard disk drives, drones, and small power tools.
