Tapered roller bearing is a precision rolling-element bearing designed to handle combined radial and heavy single-direction axial loads simultaneously. Its namesake conical geometry is key, enabling it to efficiently manage and transfer these combined loads.

Structure
A standard tapered roller bearing consists of four main components:
- Inner Ring (Cone):Features a conical raceway.
- Outer Ring (Cup):Features a matching conical-angle raceway.
- Tapered Rollers:Precisely ground conical rollers that roll between the inner and outer ring raceways. They are the core load-carrying elements.
- Cage/Retainer:Typically made of stamped steel or engineered polymer. It spaces and guides the rollers evenly, preventing contact and ensuring smooth operation.

A spherical roller bearing is a highly engineered rolling-element bearing designed to excel in demanding operating conditions. Its defining feature is its self-aligning capability. It automatically compensates for misalignment between the shaft and housing, caused by mounting errors, shaft deflection, or foundation settling (typically up to 1.5° – 3°). This…
