SKF Auto-Alignment Ball Bearing

The SKF 2307 EM is a self-aligning ball bearing designed for applications requiring compensation for shaft misalignment and angular deflection. This bearing features a cylindrical bore with an inner diameter of 35 mm, an outer diameter of 80 mm, and a width of 31 mm. The outer ring width measures 31 mm with a shoulder diameter of 67 mm, while the inner ring shoulder diameter is 46.7 mm. With a ball protrusion of 0 mm and a minimum chamfer dimension of 1.5 mm, this bearing maintains precise dimensional stability. The housing shoulder diameter maximum is 71 mm with a shaft shoulder diameter of 44 mm and a fillet radius of 1.5 mm.

This bearing delivers robust performance with a dynamic load rating of 39.7 kN and a static load rating of 11.2 kN, suitable for demanding industrial environments. The fatigue load limit is 0.59 kN, ensuring reliable operation under cyclic loading conditions. The reference speed reaches 16,000 rpm with an operational speed limitation of 12,000 rpm. Technical calculation factors include e=0.46, y0=1.4, y1=1.35, y2=2.1, and or=0.05 for precise engineering applications.

Manufactured by SKF, this bearing incorporates high-quality materials and precision engineering for consistent performance in various industrial machinery, conveyor systems, and mechanical equipment where shaft alignment compensation is essential. The self-aligning capability allows for angular misalignment up to 3 degrees, reducing stress on adjacent components and extending service life. Proper installation with appropriate lubrication and maintenance ensures optimal performance across temperature ranges from -30°C to 120°C. This bearing meets industrial standards for dimensional accuracy and load capacity, making it suitable for medium-duty applications in manufacturing, material handling, and processing equipment.
