6210 ZZ C3 KINEX 50x90x20 Deep Groove Ball Bearing

KINEX 6210 ZZ C3 50x90x20 - deep groove ball bearing for high speed industrial operation

The KINEX 6210 ZZ C3 50x90x20 deep groove ball bearing is a heavy duty radial bearing designed for industrial machinery, electric motors, pumps, gearboxes, and continuous operation drive systems. This model belongs to the highly popular Deep Groove Ball Bearings category and is engineered for reliable performance, low friction, and long operating life under demanding industrial conditions.

The bearing features double sided metal shields marked ZZ, which protect the rolling elements against dust and contamination while maintaining excellent high speed capability. The additional C3 internal clearance improves thermal compensation and allows stable operation in applications exposed to increased temperatures and high rotational speed.

What does ZZ C3 mean in the 6210 bearing?

The ZZ C3 designation identifies two important technical characteristics of the bearing.

ZZ means double sided metal shields:

• protection against dirt and dust
• reduced grease leakage
• suitable for high rotational speeds
• lower maintenance requirements

C3 means increased internal radial clearance:

• larger clearance than standard bearings
• compensates for thermal expansion
• optimized for high speed operation
• commonly used in electric motors and industrial drives

The ZZ C3 combination makes the KINEX 6210 bearing highly suitable for industrial systems operating continuously under thermal and dynamic load conditions.
