624-2Z ISB deep groove ball bearing

ISB 624 ZZ Miniature Deep Groove Ball Bearing

The ISB 624 ZZ is a high-precision, single-row miniature deep groove ball bearing. It is engineered for applications requiring high dynamics and smooth motion within strictly limited mounting spaces. Equipped with dual metal shields (ZZ), it creates a labyrinth seal that protects the raceways from dust without increasing friction torque, making it superior to rubber seals for high-speed performance.

Application

• 3D Printers & Plotters: Precise guidance for drive belts and print heads.
• RC Modeling: Perfect for brushless motors and gearboxes in remote-controlled vehicles.
• Fans & Cooling Systems: Ensures quiet operation for electronic cooling units.
• Medical Devices: Used in miniature pumps and high-precision manipulators.
• Small Electric Motors: Shaft stabilization in high-RPM drive systems.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 624 ZZ
• Type: Miniature deep groove ball bearing.
• Sealing: ZZ – non-contact metal shields on both sides.
• Maintenance: Factory pre-greased (maintenance-free).
• Material: High-grade bearing steel.

Note: Standard dimensions for the 624 are 4 mm (Bore) × 13 mm (OD) × 5 mm (Width).

Features and Benefits

• Minimal Rolling Resistance: ZZ shields do not contact the inner ring, preventing heat buildup.
• High Speed Capability: Optimized for very high rotational speeds (High-Speed applications).
• Quiet Performance: ISB’s precision-ground raceways reduce noise and vibration to a minimum.
• Grease Retention: Shields effectively keep the lubricant inside, extending the bearing's service life.
• Compact Profile: Enables extreme miniaturization of mechanical units.

Why Choose This Product

The ISB 624 ZZ bearing guarantees European quality on a micro scale. In precision devices like 3D printers or drones, the quality of the bearings directly affects the accuracy of the entire system. By choosing the ISB brand, you receive a product with consistent technical parameters that will provide your mechanisms with long, trouble-free operation without the need for frequent maintenance.
