Tapered roller bearing, pressed steel cage
The single row tapered roller bearing is available in metric dimensions (ISO 355 and JIS B 1512 standards) and in inches (ABMA standard, metric series including J). The single row in tapered roller bearing range, is the most widely used and is generally mounted in opposition.
