6004-2Z/C3 Single Row Deep Groove Ball Bearing 20×42×12mm Double Metal Shield C3 Clearance For Motor Pump Fan

The 6004-2Z/C3 is single row deep groove ball bearing equipped with double non-contact metal dust shields and C3 enlarged radial clearance. Double-sided ZZ metal shields block floating dust and retain internal grease, suitable for dry and dusty working environments. C3 extra clearance reserves expansion gap to prevent bearing seizure caused by thermal expansion under continuous high-speed and high-temperature operation. It can bear combined radial loads and light bidirectional axial loads, widely used for small industrial motors, cooling fans, miniature water pumps and light mechanical transmission parts.

Complete technical data and dimensional drawings are available upon customer request.

1. Double-sided ZZ metal dust shields provide reliable dust-proof performance, lock lubricant inside and extend maintenance cycle
2. C3 enlarged radial clearance offsets shaft thermal elongation to avoid bearing locking under long-time high-temperature running
3. Standard deep groove raceway delivers low noise, stable rotation, supporting radial and slight bidirectional axial loads simultaneously
4. Metal shield design owns excellent heat dissipation compared with rubber sealed bearings
5. Compact size saves installation space for small-size motors and ventilation equipment
6. Customizable options include CN standard clearance, 2RS rubber contact seal, OEM laser marking and special high-temperature grease
