High-Performance 1311 ETN9 Self-Aligning Ball Bearing – Durable, Versatile, and Reliable for Challenging Applications

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 1311 ETN9 Self-Aligning Ball Bearing is a robust and versatile bearing designed for optimal performance in a wide range of demanding industrial applications. This bearing features a self-aligning design that allows it to accommodate angular misalignment between the shaft and housing, ensuring smooth and reliable operation even when alignment is imperfect. Its unique spherical outer race and two rows of balls enable the bearing to compensate for misalignment caused by thermal expansion, shaft deflection, or installation errors. The 1311 ETN9 is engineered to handle both radial and axial loads in either direction, making it a dependable choice for machinery that operates under varying load conditions and requires high reliability over long periods.

Built with high-quality materials and designed for minimal maintenance, the 1311 ETN9 offers enhanced durability, resistance to wear, and exceptional load-carrying capacity, making it suitable for use in applications ranging from electric motors to agricultural machinery and conveyor systems. Whether used in high-speed or heavy-duty applications, this self-aligning ball bearing delivers consistent performance, reduces maintenance costs, and improves the overall efficiency of machinery.

Key Features:

• Self-Aligning Design: The 1311 ETN9 is equipped with a spherical outer race and two rows of balls, which allow the bearing to self-align. This feature compensates for angular misalignment, reducing wear and preventing premature bearing failure. The self-aligning capability makes it ideal for applications where shaft misalignment or deflection is common, ensuring smooth operation even in difficult conditions.

• High Load Capacity: The 1311 ETN9 is designed to support both radial and axial loads in both directions. This makes it a highly versatile bearing that can be used in a wide variety of applications, from low to moderate axial loads combined with radial loads. Its high load capacity ensures reliable performance even under heavy and fluctuating load conditions, such as those found in motors, conveyors, and agricultural machinery.

• Durable Construction: Manufactured from high-quality chrome steel (GCr15), the 1311 ETN9 is engineered for long-lasting durability and wear resistance. Chrome steel is known for its excellent mechanical properties, including high hardness, resistance to fatigue, and load-bearing capacity. The use of this premium material ensures that the bearing performs well under heavy loads and high speeds, extending its operational life and reducing the need for frequent replacements.

• Steel Cage for Enhanced Performance: The 1311 ETN9 features a steel cage that helps to evenly space the balls within the bearing. This cage design reduces friction, minimizes heat generation, and ensures smooth operation, even at higher speeds. The cage also prevents direct ball-to-ball contact, further reducing wear and enhancing the bearing's performance and reliability.

• Corrosion Resistance: The 1311 ETN9 is built to resist corrosion, making it suitable for use in environments where moisture or contaminants are present. This feature ensures that the bearing remains reliable over time, even in harsh conditions such as those found in the food processing, marine, and agricultural industries.

• Low Maintenance and Cost-Effective: Due to its self-aligning design and high-quality construction, the 1311 ETN9 requires minimal maintenance. Its ability to handle misalignment reduces the need for frequent adjustments, lowering maintenance costs and reducing downtime. The bearing’s long service life and reliability provide a cost-effective solution for industries looking to improve efficiency while minimizing operational expenses.
