These bearings consist of a cone (inner ring + rollers + cage) and a cup (outer ring) shaped like truncated cones. The rollers and raceways align to converge at a common apex, enabling smooth load transfer.

They handle combined radial and axial loads in one direction. The taper angle determines axial capacity—larger angles carry more axial load.

No, single-row types support axial loads in only one direction. To handle axial thrust both ways, they are paired in back-to-back (O), face-to-face (X), or tandem arrangements.

1. Cone assembly: inner ring, tapered rollers, cage 2.Cup: outer ring. These combine to manage loads effectively.

1. Press-fit on rotating ring; clearance fit on stationary 2.Thermal fit: heating to ~300°F maximum 3. Hydraulic pressing for large bearings.

By tightening the second bearing in a pair until the desired internal preload or clearance is achieved, often measured manually through rotational resistance.

1. High load capacity due to linear contact 2.Good stiffness and rigidity 3.Suitable for heavy-duty, moderate-speed applications.

1. More complex mounting and alignment are needed. 2. Axial load only in one direction, so need to pair 3. Not self-aligning; sensitive to misalignment 4. Lower maximum speed compared to ball or cylindrical bearings.

1. Wear and abrasion from contaminants 2.Pitting and fatigue on raceways 3. Corrosion due to moisture 4. Insufficient lubrication leading to overheating or surface damage.
