Reliable and Durable 1312 ETN9 Self-Aligning Ball Bearing – High Performance for Heavy-Duty and High-Speed 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 1312 ETN9 Self-Aligning Ball Bearing is a robust, high-performance bearing designed to provide exceptional reliability and durability in demanding applications. Featuring a self-aligning design, this bearing compensates for angular misalignment between the shaft and housing, ensuring smooth and efficient operation even when alignment is imperfect. The unique spherical outer race and two rows of balls allow the 1312 ETN9 to handle both radial and axial loads in either direction, making it an extremely versatile bearing ideal for a wide range of industrial uses.

Engineered from high-quality materials, the 1312 ETN9 offers superior wear resistance, high load capacity, and a long service life. Its self-aligning capabilities reduce friction and minimize the risk of premature failure due to misalignment or shaft deflection, which are common in many heavy-duty and high-speed machinery applications. Whether used in electric motors, agricultural equipment, conveyors, or other industrial machinery, the 1312 ETN9 ensures reliable, low-maintenance performance in the most challenging environments.

Key Features:

• Self-Aligning Design: The 1312 ETN9 features a spherical outer race and two rows of balls that allow the bearing to self-align with the shaft. This ability to compensate for angular misalignment helps reduce wear caused by misalignment, thereby extending the life of both the bearing and the equipment. This feature is especially beneficial in applications where shaft deflection, thermal expansion, or installation errors may lead to misalignment.

• High Load Capacity: The 1312 ETN9 is engineered to support both radial and axial loads in either direction. Its high radial load capacity makes it an ideal solution for machinery that experiences heavy, fluctuating loads, while its ability to support moderate axial loads ensures versatility across various applications. This combination of load-carrying capability and reliability makes the bearing perfect for demanding applications.

• Durable Construction: Manufactured from high-quality chrome steel (GCr15), the 1312 ETN9 provides excellent mechanical properties, including superior hardness, wear resistance, and fatigue strength. Chrome steel is a material known for its ability to withstand high pressures, high temperatures, and heavy loads, giving the bearing long-lasting durability in harsh environments.

• Steel Cage for Smooth Operation: Equipped with a steel cage, the 1312 ETN9 ensures proper spacing of the balls within the bearing, reducing friction and heat generation. The steel cage design also prevents ball-to-ball contact, further enhancing smooth operation and reducing the risk of wear, which is crucial for maintaining consistent performance at high speeds.

• Corrosion Resistance: The 1312 ETN9 is resistant to corrosion, making it suitable for use in environments exposed to moisture, dirt, and other contaminants. This corrosion-resistant property is particularly beneficial in industries such as agriculture, food processing, and marine applications, where exposure to harsh conditions is common.

• Low Maintenance and Cost-Effective: The self-aligning design reduces the need for frequent maintenance or realignment, making the 1312 ETN9 a cost-effective choice for industries looking to reduce downtime and operational costs. Its durability and ability to handle misalignment also help minimize the frequency of replacements, providing a long service life and reliable operation.
