SKF 2204 E2RS1TN9 Self-Aligning Ball Bearing 20x47x18

Applications of SKF 2204 Self-Aligning Ball Bearing

The SKF 2204 E2RS1TN9 self-aligning ball bearing is designed for industrial applications where shaft misalignment, mounting inaccuracies or housing deflection may occur. Its self-aligning design allows automatic compensation of angular misalignment, reducing internal stresses and improving system reliability.

This bearing is commonly used in electric motors, fans, pumps, conveyors, industrial machinery and equipment where stable operation and low maintenance are required. It is suitable for installation in bearing housings or as part of a complete bearing unit.

Advantages of SKF 2204 E2RS1TN9 Bearing

The SKF 2204 E2RS1TN9 features a double-row ball design that ensures smooth operation, low friction and balanced load distribution. The E2RS1 seals on both sides protect the bearing from dust, moisture and contamination, significantly extending service life and reducing maintenance requirements.

The TN9 polyamide cage offers low weight, good wear resistance and stable performance at higher rotational speeds. Together, these features provide high durability and reliable operation in demanding industrial environments.
