2210 ETN9 SKF Self Aligning Ball Bearing 50x90x23

PRODUCT DESCRIPTION

2210 ETN9 SKF is a self aligning ball bearing designed for industrial applications where shaft misalignment, vibration, and variable loads are present.

This model belongs to the SKF self aligning ball bearings category and features a double row ball design combined with a spherical outer ring raceway. This construction enables automatic alignment during operation, reducing internal stress and extending bearing life. Compared to standard deep groove ball bearings, it provides improved tolerance to mounting inaccuracies and shaft deflection.

Construction and design

The SKF 2210 ETN9 bearing is engineered for durability and efficient operation in demanding industrial environments.

Key design features:

• double row self aligning ball bearing

• spherical outer ring raceway for misalignment compensation

• ETN9 polyamide cage for reduced friction

• open design for flexible lubrication

The polyamide cage reduces friction and heat generation, allowing higher rotational speeds and improved efficiency.
