2211 ETN9 SKF Self Aligning Ball Bearing 55x100x25

PRODUCT DESCRIPTION

2211 ETN9 SKF is a self aligning ball bearing designed for industrial systems 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 with a spherical outer ring raceway. This construction allows automatic alignment during operation, reducing internal stress and significantly extending bearing service life. Compared to standard deep groove ball bearings, it provides higher tolerance to mounting inaccuracies and shaft deflection.

Construction and design

The SKF 2211 ETN9 bearing is engineered for durability and efficient performance in demanding industrial conditions.

Key design features:

• double row self aligning ball bearing

• spherical outer ring raceway for automatic alignment

• ETN9 polyamide cage with reduced weight

• open design for flexible lubrication options

The ETN9 polyamide cage minimizes friction and heat generation, allowing higher rotational speeds and improved efficiency.

Industrial applications

The SKF 2211 ETN9 55x100x25 bearing is widely used across multiple industrial sectors where alignment conditions are not ideal.

Typical applications include:

• industrial machinery and production lines

• conveyor systems and material handling
