NSK Self-Aligning Ball Bearings: Precision and Versatility

Introducing the NSK Self-Aligning Ball Bearings, a reliable and versatile solution for various machinery and equipment. These bearings are designed to provide exceptional performance and durability, making them an ideal choice for demanding applications. The core features of these bearings include their self-aligning capability, which allows them to accommodate minor misalignments and maintain optimal performance even under uneven loads. This design is particularly beneficial for applications where shafts may bend or housing misalignment is a concern. The cylindrical bore design ensures a secure fit in various mounting configurations.

Technical Specifications and Performance

Featuring the model number 1317, these bearings boast a diameter of 85mm, making them suitable for a wide range of applications. The outer ring of these self-aligning ball bearings features a spherical raceway, enabling the axis of the inner ring, balls, and cage to deflect to some extent around the bearing center. This design feature allows the bearings to compensate for minor misalignments, enhancing their overall performance. The table below highlights the key specifications and performance parameters of this bearing, including boundary dimensions, basic load ratings, limiting speeds, and axial load factors.
