High-Performance 2311 Self-Aligning Ball Bearing – Durable, Reliable, and Versatile 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 2311 Self-Aligning Ball Bearing is an advanced, high-performance bearing designed to deliver exceptional reliability, long service life, and smooth operation across a wide range of industrial applications. Featuring a unique self-aligning design, this bearing compensates for angular misalignment between the shaft and housing, ensuring optimal performance even when alignment is less than perfect. This self-aligning capability helps reduce friction, wear, and premature failure, making it ideal for high-speed and heavy-load environments where precision and durability are paramount.

Constructed from high-quality materials, the 2311 Self-Aligning Ball Bearing offers excellent load capacity, resistance to wear, and long-lasting performance, even under demanding operating conditions. It is engineered to handle both radial and moderate axial loads in both directions, making it versatile for use in a wide range of machinery, including electric motors, industrial equipment, and conveyors. Whether used in high-speed machinery or heavy-duty applications, the 2311 provides the reliability and durability needed to improve operational efficiency and minimize downtime.

Key Features:

• Self-Aligning Design: The 2311 Self-Aligning Ball Bearing features a spherical outer race and two rows of balls that enable it to self-align with the shaft. This design allows the bearing to compensate for angular misalignment, reducing the risks of uneven wear and premature failure. The self-aligning feature is particularly beneficial in applications where shaft deflection, thermal expansion, or misalignment is common, ensuring smooth and stable operation even in such challenging conditions.

• High Load Capacity: This bearing is engineered to support both radial and axial loads in both directions. The 2311 can efficiently handle heavy radial loads and moderate axial loads, making it suitable for use in a variety of industrial applications. Its robust load capacity ensures long-lasting performance, even under fluctuating and heavy-load conditions, which is essential for equipment like motors, pumps, and conveyors that experience varying operational demands.

• Durable Chrome Steel Construction: Manufactured from high-quality chrome steel (GCr15), the 2311 Self-Aligning Ball Bearing offers superior strength, wear resistance, and toughness. Chrome steel is known for its ability to withstand high loads, high speeds, and harsh conditions, providing the bearing with a long service life and reducing the need for frequent replacements. This durable construction ensures that the bearing performs reliably even in tough working environments.

• Steel Cage for Smooth Operation: The 2311 comes equipped with a steel cage that ensures the proper spacing of the balls, reducing friction and minimizing heat buildup. This cage design helps prevent ball-to-ball contact and ensures smooth operation, even at higher speeds. The steel cage further enhances the bearing's performance by providing added resistance to wear and improving overall reliability.

• Corrosion Resistance: The 2311 Self-Aligning Ball Bearing is designed to resist corrosion, making it suitable for use in harsh environments where moisture, dust, or other contaminants may be present. Its corrosion-resistant properties ensure reliable performance and a long service life, even in applications such as food processing, agriculture, and marine industries, where exposure to corrosive elements is common.

• Low Maintenance and Cost-Effective: Thanks to its self-aligning design and durable construction, the 2311 requires minimal maintenance. The ability to accommodate misalignment reduces the need for frequent adjustments, resulting in lower maintenance costs and reduced downtime. This makes the 2311 Self-Aligning Ball Bearing a cost-effective solution for industries seeking high performance, low-maintenance, and high reliability.
