604 ZZ Deep Groove Ball Bearing 4×12×4 mm | ISO 60 Series – Extra Light | Double Shielded
Premium miniature precision bearing featuring the universal deep groove geometry. Engineered for reliable high-speed performance up to 38,000 r/min (Oil). The 604-ZZ is capable of supporting radial loads and light axial loads, making it ideal for small precision devices, micro-motors, and instrumentation.

Ideally suited for a broad spectrum of precision and industrial equipment:
The double non-contact steel shields guard both sides against dust and larger particles while retaining lubrication and maintaining minimal friction. This design is ideal where contamination resistance is needed without compromising low rotational torque.
With its extra-light series construction, the bearing offers a compact cross-section and a reduced footprint, delivering reliable load capacity in tight spaces commonly found in miniature mechanisms and small electronic assemblies.
Manufactured to standard industrial tolerances and available in optional precision grades, its optimized internal geometry ensures smooth rotation, low noise, and reduced heat buildup—supporting consistent operation in noise-sensitive and precision devices.
