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

The 6220-2Z/C3 is single row deep groove ball bearing fitted with double non-contact metal dust shields and C3 enlarged radial clearance. Double-sided ZZ metal shields block floating dust and seal internal grease inside the bearing, ideal for dry, dusty industrial operating environments. C3 extra internal clearance reserves expansion space to eliminate thermal expansion jamming under continuous high-speed and high-temperature running conditions. It supports combined radial loads and light bidirectional axial loads, widely applied for large industrial fans, heavy-duty driving motors, water pumps and general heavy rotary machinery.

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

• Double-sided ZZ metal dust shields deliver reliable dust-proof performance, lock lubricant inside and extend maintenance intervals
• C3 enlarged radial clearance offsets shaft thermal elongation, effectively prevent bearing seizure during long-time high-temperature operation
• Standard deep groove raceway design ensures low vibration, low noise and stable rotation, bears radial and slight bidirectional axial loads simultaneously
• Metal shield structure features superior heat dissipation performance compared with rubber sealed bearings
• Large load capacity matches heavy-duty medium-speed industrial rotary equipment
• Customizable options include CN standard clearance, 2RS rubber contact seal, OEM laser marking and special high-temperature lubricating grease

This bearing is widely matched for the following heavy industrial equipment:

• Large industrial high-temperature fan and blower main rotary shafts
• Heavy-duty driving motor rotor supporting assemblies
• Large flow industrial water pump rotary transmission parts
• Cement, mining and textile heavy-duty machinery transmission units
• General heavy rotary equipment aftermarket replacement spare parts

• 25 years of professional deep groove ball bearing manufacturing experience
• Products exported to more than 50 countries and regions around the world
