FAG 61868-MA-C3 340x420x38 deep groove ball bearing

Main Description

The FAG 61868-MA-C3 340x420x38 is a large size deep groove ball bearing designed for heavy industrial applications requiring high load capacity, stable rotational performance, and reliable operation at elevated speeds.

This model belongs to the thin section Deep Groove Ball Bearings category commonly used in large drive systems, industrial machinery, turbines, electric motors, and equipment requiring high efficiency combined with reduced cross section dimensions. The 618 series design allows a large bearing diameter while maintaining a relatively slim bearing profile.

The 340x420x38 dimensions make this bearing suitable for demanding industrial systems requiring accurate rotation and stable operation under heavy loads. The MA designation indicates a machined brass cage guided on the outer ring, providing increased durability and operational stability at high rotational speeds. The C3 internal clearance is designed for applications operating at elevated temperatures and increased rotational speeds.
