Designation:

• 3490/3420 (ANSI/ABMA 19.2);
• 3490 - cone part number;
• 3420 - cup part number

Design:

The bearing consists of two rings (inner and outer) and rolling elements (tapered rollers) which are connected by a cage. The inner ring with a cage and rolling elements is a CONE. The outer ring is a CUP.

Features:

The design of tapered roller bearings suites for the perception of combined (radial and axial) loads. Tapered roller bearings have a split construction: the inner ring with the rollers and separator create the unit, that can be mounted separately from the outer ring. Tapered roller bearings are inches.
