The 31313 Tapered Roller Bearing is a robust single-row component engineered to manage high combined loads-simultaneously supporting heavy radial forces and substantial axial forces in one direction. This versatility comes from its conical design, where the rollers and raceways are tapered, allowing them to effectively distribute stress across the contact surfaces. The bearing is easily separable into two main components: the cone (inner ring assembly, containing the rollers and cage) and the cup (outer ring), which simplifies mounting, dismounting, and routine maintenance. With standard metric dimensions of 65 mm bore, 140 mm outside diameter, and a total width of 36 mm, the 31313 series is a widely adopted solution across various demanding industries.
