Heavy-duty application 2309 ETN9 Self-Aligning Ball Bearing Robust

Self-aligning ball bearing
Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

    Accommodate static and dynamic misalignment
    Excellent high-speed performance
    Excellent light load performance
    Low friction

Knowledge and introduction of bearings

The 2309 ETN9 Self-Aligning Ball Bearing is a premium-quality, high-performance bearing designed to provide superior reliability, durability, and efficiency across a wide range of industrial applications. Engineered to handle both radial and axial loads, this bearing features a self-aligning design that allows it to compensate for shaft misalignment or deflection. It is the perfect solution for machinery and equipment that operates under fluctuating loads or challenging conditions, where precise alignment cannot always be maintained. Whether used in automotive, manufacturing, or heavy-duty industrial machinery, the 2309 ETN9 ensures smooth operation and extended service life.

Key Features:

• Self-Aligning Design: The 2309 ETN9 features a unique design with two rows of balls and a spherical outer raceway. This design allows the bearing to self-align, compensating for any misalignment of the shaft and housing, ensuring optimal performance even in cases of angular misalignment or shaft deflection. This feature significantly reduces wear and prolongs bearing life.

• High Load Capacity: This bearing is capable of handling both radial and axial loads in both directions, making it highly versatile and capable of withstanding heavy-duty applications. Whether subjected to dynamic loads or shock loads, the 2309 ETN9 provides the strength and reliability required for demanding conditions.

• Durable Construction: Manufactured from high-quality chrome steel (GCr15), the 2309 ETN9 provides excellent wear resistance and durability. Its robust construction ensures that it performs reliably even under extreme conditions, including high speeds and variable temperatures.

• Steel Cage for Optimal Ball Spacing: The steel cage design of the 2309 ETN9 ensures the balls remain evenly spaced, reducing friction and heat buildup. This minimizes wear on the bearing surfaces and ensures smooth operation even at higher speeds.

• Corrosion-Resistant Materials: The 2309 ETN9 is built to withstand corrosion, making it a reliable option for use in harsh environments such as food processing, agriculture, or marine applications. The materials used are resistant to oxidation, ensuring long-lasting performance even in humid or corrosive conditions.

• Wide Application Range: The 2309 ETN9 is commonly used in applications such as electric motors, gearboxes, pumps, conveyors, and more. Its self-aligning feature makes it ideal for machines with shafts that may experience slight deflections or misalignment during operation.

• Reduced Maintenance: Due to its robust construction and self-aligning properties, this bearing requires minimal maintenance. It reduces the need for constant adjustments or realignment, which ultimately lowers maintenance costs and reduces downtime in industrial settings.

Technical Specifications:

• Inner Diameter (d): 45 mm

• Outer Diameter (D): 100 mm
