Durable and High-Performance 2212 ETN9 Self-Aligning Ball Bearing – Reliable, Versatile, and Ideal for Heavy-Duty 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 2212 ETN9 Self-Aligning Ball Bearing is a high-performance, durable bearing designed for applications that demand both reliability and versatility. With its innovative self-aligning design, this bearing is capable of compensating for angular misalignment between the shaft and housing, ensuring smooth operation even in cases where alignment is less than perfect. This self-aligning feature is particularly beneficial in applications where shaft deflection, misalignment, or thermal expansion can lead to alignment issues. The 2212 ETN9 is engineered to handle both radial and axial loads in both directions, making it a versatile and cost-effective solution for a wide range of industrial applications.

Constructed from high-quality materials, the 2212 ETN9 offers exceptional load capacity, wear resistance, and long-lasting performance, even under demanding conditions. It is well-suited for high-speed applications as well as heavy-duty machinery that requires a bearing with excellent load-carrying capability and minimal maintenance. Whether used in motors, agricultural machinery, conveyors, or other heavy-duty equipment, the 2212 ETN9 ensures optimal performance, reduces downtime, and lowers maintenance costs.

Key Features:

• Self-Aligning Design: The 2212 ETN9 features a spherical outer race and two rows of balls, enabling the bearing to self-align with the shaft. This design compensates for angular misalignment, reducing wear and preventing premature bearing failure. The self-aligning feature is ideal for applications where precise alignment is difficult to achieve, such as in motors, conveyors, and other rotating machinery that experiences misalignment or shaft deflection.

• High Load Capacity: The 2212 ETN9 is designed to support both radial and axial loads in both directions. This makes it an excellent choice for applications that experience combined radial and moderate axial loads. The bearing is capable of handling significant radial loads, making it suitable for equipment operating under heavy or fluctuating load conditions, such as industrial motors, pumps, and heavy machinery.

• Durable Construction: Manufactured from high-quality chrome steel (GCr15), the 2212 ETN9 provides exceptional strength, wear resistance, and durability. Chrome steel is known for its ability to withstand high loads, high speeds, and harsh conditions, giving the bearing a long service life and reducing the need for frequent replacements. This durable construction is key to ensuring consistent performance, even in demanding environments.

• Steel Cage for Reduced Friction: The 2212 ETN9 features a steel cage that ensures proper ball spacing, reducing friction and preventing ball-to-ball contact. This cage design minimizes heat buildup and ensures smooth operation at higher speeds, extending the bearing's service life. The steel cage also reduces the risk of wear, making the bearing more reliable and efficient.

• Corrosion Resistance: The 2212 ETN9 is designed to resist corrosion, making it an excellent choice for use in environments where moisture, dust, or other contaminants are present. This corrosion-resistant feature ensures that the bearing maintains reliable performance over time, even in harsh working conditions such as those found in food processing, agriculture, and marine environments.

• Low Maintenance and Cost-Effective: The self-aligning design and durable materials used in the construction of the 2212 ETN9 reduce the need for frequent maintenance. Its ability to accommodate misalignment minimizes the requirement for realignment and adjustments, lowering maintenance costs and reducing downtime. This makes the 2212 ETN9 a highly cost-effective solution for industries seeking high performance with minimal maintenance.
