SKF Double Row Tapered Roller Bearings

What Are SKF Double Row Tapered Roller Bearings?

SKF double row tapered roller bearings consist of two rows of tapered rollers arranged back‑to‑back or face‑to‑face within a single unit. The raceways and rollers are designed so that their contact lines converge at a common point on the bearing axis, allowing the bearing to carry combined loads and provide precise axial location.

Unlike single row tapered roller bearings, which support axial load in one direction only, double row designs can support axial loads in both directions, simplifying the bearing arrangement and saving space.

Typical Applications

SKF double row tapered roller bearings are used in applications where high stiffness, accurate shaft guidance and bi‑directional axial load capacity are essential, including:

• Gearboxes and industrial gear units
• Rolling mill roll necks and metal processing equipment
• Wheel hubs and axle units (industrial and off‑highway)
• Wind turbine gearboxes and drives
• Mining, quarrying and construction machinery
• Heavy‑duty pumps and compressors
• General heavy industrial machinery

Their ability to handle combined loads and maintain precise alignment makes them a dependable choice for critical rotating equipment.

Performance and Reliability

SKF double row tapered roller bearings are engineered to:

• Deliver long service life under high radial and axial loads
• Provide high stiffness for precise shaft guidance and gear mesh control
• Maintain performance in the presence of vibration, shock and variable loading
• Reduce unplanned downtime and maintenance interventions
• Lower total cost of ownership through improved reliability and reduced component count

Correct mounting, setting, lubrication and sealing are key to achieving the full performance potential of these bearings.
