S623 Bearing Product Overview & Core Advantages
The S623 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its compact dimensions (3mm bore, 10mm OD, 4mm width) and low weight (1.45g), making it ideal for space-constrained assemblies. Its open design allows for versatile lubrication options to meet specific operational needs.
S623 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S6 | Series designation, indicating a specific size and performance category for miniature and instrument ball bearings. |
| 23 | Bore diameter code, specifying a 3 mm bore. |
| Open (No Seal Suffix) | The bearing is supplied without seals or shields, allowing for maximum speed capability and custom lubrication. |
| ABEC1 | Specifies the precision tolerance class, ensuring runout and dimensional accuracy suitable for a wide range of industrial applications. |
| MC3 Clearance | Denotes a normal radial internal clearance group, providing optimal performance under standard operating conditions and temperatures. |
S623 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The deep, continuous raceways on both rings enable the S623 to handle significant radial dynamic load ratings (108 lbf) and static loads (36 lbf) for its size.
- All-Stainless Steel Construction: The rings, balls, and stainless steel cage provide superior corrosion resistance, making the bearing suitable for harsh environments and ensuring long-term operational integrity.
- Optimized for High Speeds: The open design and precision engineering contribute to a high limiting speed of 45,000 rpm, which is essential for applications like small motors and high-speed spindles.
- Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3), this bearing ensures smooth, quiet, and low-vibration operation.
S623 Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Optical Encoders
- Medical Devices and Dental Handpieces
- Office Automation Equipment (e.g., Printers, Scanners)
- Robotics and Small Actuators
- Radio-Controlled Models and Drones
