Ball bearing sizes Self-aligning ball bearing 2308 Specification of self-aligning ball bearing: The outer ring raceway of aligning ball bearing is processed into a spherical shape, so it has aligning performance. It is mainly used to bear radial load, when bearing radial load, it can also withstand a small amount of axial load. But generally it cannot be subjected to bear pure axial load, the ultimate speed is lower than deep groove ball bearings. Such bearings are mostly used on the double-support shaft prone to bending under load, and a dual bearing seat hole can not guarantee the strict concentricity parts, but the relative inclination of the centerline of the inner ring and the outer ring may not exceed 3°. Because the contact area of ball and raceway is small, so that the load capacity of this kind of bearing is low, life is short, so its usage rang is gradually reduced, and there will be the trend it will be replaced by self-aligning roller bearings. Inner bore of this kind of bearing has two types of cylindrical and conical Company Culture --Enterprise group combines industry with International trade --The 18 yearsspecializing in bearing --well-equipped testing equipment and strong technical force --Have exported to Europe, America, Africa, Middle East, Asia, Pakistan, etc. --Products widely used in pulley, toys, furniture, aircraft model, textiles, machinery and electronics, power tools, household appliances, medical equipment, motorcycles, and fitness equipment and so on. --With a wide range, good quality, competitive prices and stylish designs, our products are widely recognized and trusted by users and can meet continuously developing economic and social needs. --More product supply:self-aligning ball bearing,spherical roller bearing,taper roller bearing,thrust ball bearing,thrust roller bearing,cylindrical roller bearing and other ball or roller bearings. .
