Single Row Taper Roller Bearing

A single row taper roller bearing is a type of rolling element bearing that can support axial and radial loads in one direction. It is designed to handle both thrust (axial) and radial forces simultaneously, making it a versatile choice for various applications. This type of bearing consists of an inner ring, an outer ring, tapered rollers, and a cage to keep the rollers evenly spaced.
