What are double row tapered roller bearings and where are they used?

The double-row tapered roller bearing assembly has tapered contact angles that allow them to support both radial and axial thrust loads simultaneously. The two rows of tapered rollers give the bearing an outstanding load capacity, making these bearings one of the most robust. These bearings have a low friction design, which reduces the running temperature of the bearing, increasing efficiency and prolonging the life of the bearing

Used in gearboxes, rolling mills, and hoisting equipment, particularly in the mining and quarrying industry, this type of bearing is available in two different versions, however, both ultimately consist of cups and cones.

  • Double-cone type: This assembly has two separate cups which fit onto one dual cone.
  • Double-cup type: This assembly has two separate cones which fit into the ends of one dual cup.

Double Row Tapered Roller Bearings FAQs

What are double row tapered roller bearings?

Double-row tapered roller bearings are rolling-element bearings engineered to carry heavy radial loads and axial loads in both directions. With two rows of tapered rollers arranged back-to-back, they deliver higher load capacity and greater rigidity than single-row designs.

How do double row tapered roller bearings differ from single row types?

Although both types use tapered rollers, double‑row bearings incorporate two symmetrical roller sets. As a result, they:

  • Support axial loads in both directions
  • Offer higher radial and thrust load capacity
  • Provide improved shaft guidance and alignment

How do I choose the right double row tapered roller bearing?

When selecting a bearing, consider:

  • Load type: radial, axial, or combined
  • Shaft and housing dimensions
  • Operating speed
  • Temperature and environmental conditions
  • Mounting method and space constraints

For optimal sizing and performance, consult our bearing specialists or use the manufacturer’s selection tools.
