Reliable and High-Performance 1212 ETN9 Self-Aligning Ball Bearing – Durable, 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.

Knowledge and introduction of bearings

The 1212 ETN9 Self-Aligning Ball Bearing is a high-quality, durable bearing designed to deliver reliable and long-lasting performance in demanding industrial applications. Featuring a unique self-aligning design, this bearing compensates for angular misalignment between the shaft and housing, ensuring smooth operation even in conditions where alignment is not perfect. Its ability to accommodate both radial and moderate axial loads in both directions makes it a versatile and cost-effective solution for a wide range of applications. Whether used in high-speed machinery or heavy-duty equipment, the 1212 ETN9 provides optimal performance, reduces maintenance costs, and improves the overall efficiency of your machinery.

Constructed from high-quality materials, the 1212 ETN9 Self-Aligning Ball Bearing is engineered to withstand harsh operating conditions, providing excellent load capacity, wear resistance, and durability. Its self-aligning feature reduces friction and prevents premature bearing failure caused by misalignment, making it an ideal choice for equipment prone to misalignment or shaft deflection.

Key Features:

• Self-Aligning Design: The 1212 ETN9 features a spherical outer race and two rows of balls, allowing the bearing to self-align with the shaft. This self-aligning design enables the bearing to compensate for angular misalignment or shaft deflection, reducing wear and extending the bearing’s service life. It is especially useful in applications where alignment issues are common, such as in motors, conveyors, or agricultural machinery.

• High Load Capacity: The 1212 ETN9 is capable of handling both radial and moderate axial loads in both directions. This makes it a versatile bearing ideal for applications that experience fluctuating or combined load conditions. Its high radial load capacity and ability to handle moderate axial loads make it suitable for a wide variety of machinery, from low- to moderate-speed applications to those subject to higher loads.

• Durable Chrome Steel Construction: Made from premium chrome steel (GCr15), the 1212 ETN9 offers exceptional durability, wear resistance, and strength. Chrome steel is known for its ability to withstand high loads, high speeds, and harsh operating environments, providing the bearing with a long service life and reducing the need for frequent maintenance or replacement.

• Steel Cage for Smooth Operation: The 1212 ETN9 comes equipped with a steel cage that ensures the proper spacing of the balls, reducing friction and preventing ball-to-ball contact. This cage design helps to minimize heat buildup and ensures smooth operation at higher speeds. It also enhances the bearing’s overall performance by providing additional resistance to wear, improving its reliability over time.

• Corrosion Resistance: The 1212 ETN9 is designed to resist corrosion, making it suitable for use in environments where moisture, dust, or other contaminants are present. This corrosion-resistant feature is essential for applications in industries such as food processing, textiles, agriculture, and other environments where bearings are exposed to harsh conditions. It ensures that the bearing continues to perform reliably, even in challenging working environments.

• Low Maintenance and Cost-Effective: Thanks to its self-aligning feature and durable construction, the 1212 ETN9 requires minimal maintenance. The self-aligning design reduces the need for frequent adjustments or realignments, lowering maintenance costs and reducing downtime. This makes the 1212 ETN9 a cost-effective solution for industries looking to improve operational efficiency while minimizing maintenance expenses.
