6206-ZZ Ball Bearing C3 Clearance

The 6206-ZZ Ball Bearing C3 Clearance is a deep groove ball bearing designed for applications requiring high rotational speed, thermal stability, and continuous-duty industrial performance.

Measuring 30x62x16mm, this bearing features double metal shields (ZZ) combined with C3 internal clearance, making it ideal for equipment operating at higher RPM and elevated temperatures. Manufactured from chrome steel and supplied factory pre-lubricated, the bearing delivers efficient rotation, lower friction, and dependable durability in industrial systems.

Applications for the 6206-ZZ C3

The 6206-ZZ C3 is commonly used in equipment operating under high speed and continuous thermal expansion conditions, including:

• Industrial electric motors
• Industrial pumps
• Gearboxes
• Conveyor systems
• Industrial fans
• Agricultural machinery
• CNC equipment
• Alternators and generators

C3 clearance bearings are widely selected when a system experiences operational heat and requires increased internal tolerance during thermal expansion.
