1309 ETN9 SKF Self Aligning Ball Bearing 45x100x25

PRODUCT DESCRIPTION

1309 ETN9 SKF is a self aligning ball bearing designed to operate reliably in applications exposed to shaft misalignment and dynamic radial loads in industrial systems.

This model belongs to the SKF self aligning ball bearing category and features a double row design with a spherical outer ring raceway, allowing automatic alignment during operation. Compared to standard deep groove ball bearings, this design significantly improves performance in systems where shaft deflection or mounting inaccuracies occur.

Industrial applications

The SKF 1309 ETN9 45x100x25 self aligning ball bearing is widely used in demanding industrial environments where reliability and flexibility are essential.

Typical applications include:

• industrial machinery and production lines

• ventilation systems and fans

• conveyors and material handling equipment

• agricultural machinery

• pumps and transmission systems

Its ability to compensate for angular misalignment makes it especially suitable for installations where perfect alignment cannot be guaranteed.

Construction and design

The SKF 1309 ETN9 bearing is engineered with advanced materials and geometry for optimal performance.

Key design features:

• double row self aligning ball bearing

• spherical outer ring raceway

• lightweight ETN9 polyamide cage
