624-2Z/LHT23 Bearing Product Overview & Core Advantages
The 624-2Z is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Its key advantage lies in its ability to efficiently handle radial loads while offering a sealed design for enhanced protection. This bearing is engineered for applications requiring a balance of performance, durability, and cost-effectiveness, making it a versatile choice for various industrial and precision mechanisms. The combination of shields (2Z) and high-quality chrome steel construction ensures long service life and consistent operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 624 | Basic series designation for a single row deep groove ball bearing with a 4 mm bore. |
| 2Z | Indicates the bearing is shielded on both sides. These non-contact steel shields protect the internal components from large contaminants while minimizing friction, contributing to the bearing's limiting speed. |
624-2Z/LHT23 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing provides high strength, wear resistance, and consistent performance under radial dynamic load ratings of 249 lbf.
- Sealed for Protection: The double-shielded (2Z) design effectively retains the factory-applied lubrication and excludes larger particulate contaminants, enhancing reliability and reducing maintenance needs in dirty environments.
- Precision & Stability: Built to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance, it offers reliable running accuracy and smooth operation for general applications.
- Compact & Lightweight: With dimensions of 4 mm (bore) x 13 mm (OD) x 5 mm (width) and a weight of only 3.1 g, it is ideal for applications where space and weight are critical constraints.
624-2Z/LHT23 Bearing Typical Application Areas
The 624-2Z is commonly specified in a wide range of compact and precision devices, including:
- Small electric motors and gearboxes
- Precision instruments and optical devices
- Office machinery (e.g., printers, scanners)
- Computer cooling fans and small spindles
- Medical devices and laboratory equipment
- Radio control models and small power tools
