6220‑2Z/C3 Single Row Deep Groove Ball Bearing 100×180×34mm C3 Clearance Double Metal Shield

The 6220‑2Z/C3 is single row deep groove ball bearing fitted with double non‑contact metal dust shields and C3 enlarged radial clearance. The C3 clearance compensates thermal expansion under high‑speed, high‑temperature operation, while ZZ shields block dust and retain internal grease. It bears combined radial and light bidirectional axial loads.

It is widely applied in large fans, heavy motors and industrial equipment running at elevated temperature.

• C3 extra clearance avoids bearing jamming caused by thermal expansion
• Double metal shield design blocks floating dust and keeps lubricant inside
• Optimized raceway ensures low noise and stable medium‑high speed rotation
• Handles combined radial and light axial loads continuously
• Suitable for high‑temp heavy‑load industrial motors, large fans and pumps
• Custom service: standard clearance conversion, special grease, OEM laser marking

This bearing is widely used in:

• Large industrial driving motors and high‑temperature fan shafts
• Heavy‑duty water pumps and air blower rotary assemblies
• Textile machinery main transmission shafts
• General heavy industrial rotary equipment
• Mechanical equipment aftermarket replacement parts
