Product Overview: The 3490/20 Inch Tapered Roller Bearing
The 3490/20 is a high-performance inch series Tapered Roller Bearing, consisting of the 3490 cone and the 3420 cup. With a bore diameter of 44.45mm, an outer diameter of 82.55mm, and a total width of 20.638mm, this bearing is engineered to manage both radial and axial loads simultaneously. Its unique tapered design allows the projected raceways to converge at a common point on the bearing axis, providing true rolling motion and low friction. This makes it exceptionally suitable for applications demanding high load-carrying capacity and durability.
As a key component in our Inch Tapered Roller Bearings collection, the 3490/20 is manufactured to precise industry standards. The separable design, where the cone (inner ring, rollers, and cage) and cup (outer ring) can be mounted independently, simplifies installation, inspection, and maintenance procedures. It is a reliable solution for various demanding industrial and automotive applications.
