SKF 1304 ETN9 Self Aligning Ball Bearing 20x52x15

PRODUCT DESCRIPTION

SKF 1304 ETN9 is a self aligning ball bearing designed to compensate shaft misalignment and ensure smooth operation in compact industrial systems exposed to dynamic loads.

This model belongs to the SKF self aligning ball bearings category, featuring a double row ball arrangement and a spherical outer ring raceway. This design allows automatic alignment between shaft and housing, making it ideal for applications where mounting precision is difficult to maintain. Compared to standard deep groove ball bearings, it significantly reduces stress caused by angular misalignment.

Construction and design

The SKF 1304 ETN9 bearing is engineered for efficient performance in demanding industrial environments.

Key design features:

• double row self aligning ball bearing

• spherical outer ring raceway for misalignment compensation

• lightweight ETN9 polyamide cage

• open design for flexible lubrication

The ETN9 polyamide cage reduces friction and inertia, enabling higher speeds and quieter operation, which is essential in modern machinery.
