623zz Bearing Product Overview & Core Advantages
The 623zz is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable operation. This shielded bearing offers robust radial load capacity and is pre-lubricated for immediate use. Its compact design, featuring a 3mm bore and 10mm outside diameter, makes it an ideal choice for applications where space is limited but precision and durability are paramount. Manufactured from high-grade chrome steel with a stainless steel cage, it ensures long service life and consistent performance.
623zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Indicates the bearing is equipped with non-contact shields on both sides. These shields protect the internal components from large particulate contaminants while minimizing friction, contributing to the bearing's limiting speed of 50,000 rpm. |
623zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The deep, continuous raceways on both rings enable the 623zz to handle significant radial dynamic loads (121 lbf) and moderate axial loads in both directions, providing versatile load support.
- Optimized Internal Geometry: With 7 high-precision chrome steel balls and a stainless steel cage, the bearing maintains precise ball guidance and low vibration, essential for smooth operation at high speeds.
- Shielded & Pre-Lubricated for Longevity: The dual stainless steel shields retain the factory-applied lubricant and protect against contamination, reducing maintenance needs and extending the bearing's operational life within a temperature range of -30°C to 110°C.
- Standardized Precision: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), it delivers reliable and predictable performance for a wide array of industrial applications.
623zz Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle support in miniature DC motors, fans, and drones due to its high-speed capability and compact bearing dimensions.
- Precision Instruments and Gauges: Used in medical devices, optical equipment, and measuring instruments where low noise and smooth rotation are critical.
- Office Automation Equipment: Commonly found in printers, scanners, and copiers for guiding rollers and shafts.
- Consumer Electronics: Suitable for small drives in computer hard disk drives, gaming consoles, and other compact electronic devices.
