Durable 1309 ETN9 Self-Aligning Ball Bearing – High-Performance, Reliable, and Versatile

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 1309 ETN9 Self-Aligning Ball Bearing is an advanced and highly reliable bearing solution, specifically engineered for applications that demand high performance, durability, and versatility. This bearing is ideal for handling both radial and axial loads while offering exceptional tolerance to misalignment, making it perfect for a wide range of industrial machinery, electric motors, and automotive applications. The self-aligning feature of the 1309 ETN9 ensures it can perform reliably even under misalignment or shaft deflection, ensuring a smooth operation and minimal maintenance.

Key Features:

• Self-Aligning Design: The 1309 ETN9 features a unique two-row ball arrangement and a spherical outer race, which allows the bearing to automatically compensate for any angular misalignment between the shaft and housing. This self-aligning capability ensures continuous, smooth operation even in challenging conditions.

• Robust Construction for High Load Capacity: This bearing is designed to support both radial and axial loads, providing an excellent combination of load-carrying capacity and performance. Whether under heavy or moderate loads, the 1309 ETN9 can handle demanding applications without compromising reliability.

• Long-Lasting Durability: Constructed with premium-quality materials, including high-grade chrome steel, the 1309 ETN9 offers superior wear resistance, corrosion resistance, and long service life. It is designed to perform well under harsh conditions, making it an ideal choice for a wide variety of industries.

• Steel Cage for Enhanced Performance: The bearing is equipped with a steel cage, which ensures the proper spacing of the balls, reducing friction, and preventing wear. The cage also helps in maintaining the integrity of the bearing even at higher speeds, ensuring consistent performance.

• Versatile Applications: The 1309 ETN9 is widely used in electric motors, pumps, agricultural machinery, conveyors, and more. Its excellent self-aligning ability makes it particularly useful in applications where misalignment may occur due to shaft deflection or thermal expansion.

• Low Maintenance: Due to its robust design and self-aligning capabilities, this bearing reduces the need for frequent maintenance and alignment adjustments, helping to minimize downtime and improve operational efficiency.
