GQZ 6304-2Z Single Row Deep Groove Ball Bearing 20×52×15mm Double Sided Metal Dust Shields For Light Industrial Equipment

6304-2Z is single-row deep groove ball bearing fitted with double-sided stamped metal dust shields. It bears radial load and moderate bidirectional axial load simultaneously, with low friction, stable high-speed running and reliable dry dust isolation. Metal shields only block dry dust and metal debris without waterproof function, suitable for dry, clean light-medium load machinery.

1. Double thin metal shields isolate dry dust, metal scraps and dry impurities to extend service life in dry working environments
2. Deep continuous raceway supports composite radial-axial load, fits horizontal and vertical shaft installation
3. Thickened ball structure delivers larger load capacity than 62 series bearings of same bore size
4. Light stamped steel cage reduces friction heat for steady long-hour high-speed rotation
5. Standard ISO metric size, fully interchangeable with all mainstream brand 6304-2Z bearings
6. Pre-filled universal lithium grease at factory, reduce frequent relubrication maintenance
7. Customizable options: C3 clearance, high-temperature grease, OEM laser marking, P6 / P5 precision grade
   Reduce abnormal vibration, running noise and equipment maintenance frequency.

• Small driving motors, ventilation micro fans and blowers
• Handheld power tools, medium water pumps and household appliances
• Textile, printing and packaging medium rotary rollers
• Conveyor rollers, fitness equipment moving parts
• General light-medium load transmission assemblies
