624-Z/W64 Bearing Product Overview & Core Advantages
The 624-Z/W64 is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. This shielded bearing is pre-lubricated with Soild Oil, making it a maintenance-free solution ideal for applications requiring long service life without re-lubrication. Its ABEC 1 (ISO P0) precision and standard CN radial internal clearance ensure smooth, quiet operation and consistent performance, making it a versatile and cost-effective choice for a wide range of industrial and consumer products.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 624 | Standard series designation for a single row deep groove ball bearing. |
| -Z | Denotes a shielded bearing on one side, providing effective protection against contaminants. |
| /W64 | Indicates the bearing is pre-lubricated with Soild Oil, a polymer-based lubricant offering excellent stability and long-term lubrication. |
624-Z/W64 Bearing Structural Features & Performance Benefits
- Robust Construction for Radial Loads: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing is engineered to handle the specified radial dynamic load rating of 249 lbf effectively, providing reliable performance in its size class.
- Maintenance-Free Operation: The combination of a shield (Z) and Soild Oil (W64) lubrication creates a sealed, long-life unit. This eliminates the need for re-lubrication, reduces maintenance costs, and prevents lubricant leakage.
- Precision and Smooth Operation: Built to ABEC 1 (ISO P0) tolerance standards, the bearing ensures low noise and vibration, contributing to the smooth running of the application. The standard CN radial internal clearance is suitable for most general operating conditions.
- Compact and Lightweight Design: With dimensions of 4mm (bore) x 13mm (OD) x 5mm (width) and a weight of only 3.1 grams, it is ideal for space-constrained and weight-sensitive designs.
624-Z/W64 Bearing Typical Application Areas
The 624-Z/W64 is widely used in various small machinery and precision instruments, including:
- Small Electric Motors (e.g., in fans, power tools)
- Office Automation Equipment (printers, scanners)
- Medical Devices and Laboratory Equipment
- Precision Gearboxes and Mechanisms
- Consumer Electronics and Small Appliances
