SKF Self-Aligning 2 Row Ball Bearing 55 mm ID, 120 mm OD, 29 mm Race Width 1311 EKTN9

The SKF 1311 EKTN9 is a high-quality self-aligning 2 row ball bearing manufactured in India, featuring a 55 mm inside diameter, 120 mm outside diameter, and a 29 mm race width. Its design includes a tapered bore for simplified installation and an open-ended structure facilitating free lubricant flow, critical for maintaining optimum performance in closed systems.

Engineered with a non-metallic cage and constructed from durable bearing steel, this bearing effectively stabilizes the balls and resists corrosion, ensuring long service life in demanding industrial and mechanical environments. The spherical raceway in the outer ring allows for axial and radial movement, enabling the bearing to accommodate shaft misalignment without damage.

It offers a dynamic load rating of 50.7 kN and static load rating of 18 kN, paired with a limiting speed of 7500 rpm, making it well-suited for heavy-duty applications. Typical uses include gearboxes, final drive transmissions, and vehicle differentials, where resilience to load and flexibility under misalignment are critical.

This ball bearing is part of SKF's 3 Medium series and maintains high standards of quality without additional certifications. Its open design and materials position it as an excellent choice for industrial, automotive, agricultural, and manufacturing sectors requiring reliable rotary bearing solutions.
