NTN bearing solutions are optimized to meet the severe requirements of construction equipment.

One of the largest ranges in the market

Hydraulic excavators, transmissions, road construction and repair equipment, hydraulic pumps and motors, axle bearings for rolling stock: NTN is the global benchmark for mobile construction equipment.

Robust bearings of premium quality

NTN bearings have a better useful life in reduced spaces under demanding operating conditions, such as high loads, shocks and vibrations.

Optimal reliability

To guarantee 24/7 operation demanded in the construction industry, the avoidance of machine breakdowns reduces the risk of disruption to your production.

Our teams will advise you and identify the solutions best suited to your applications.

Bearings for construction equipment NTN
Hydraulic excavators

Caterpillar track final drive: 

  • thin-section angular contact ball bearings
  • thin-section tapered roller bearings (for heavy excavators)

Turret rotation (swing drive): ULTAGE® spherical roller bearings

Planetary gears for planetary gearboxes: HWT high-capacity needle roller and cage assemblies

HWT high-capacity needle roller and cage assemblies achieve a service life of more than twice that of conventional needle roller and cage assemblies, within the space envelope. The optimised design has an increased number of rolling elements thereby increasing the load carrying capacity by 15% to 25%.

Transmission and axle bearings for rolling stock (tilting-carts, loaders, backhoe loaders):
  • tapered roller bearings
  • deep groove ball bearings
  • cylindrical roller bearings
  • needle roller bearings
  • and more generally, large bearings, such as tapered roller bearings with an outer diameter of more than 800mm

NTN bearings for construction
Construction and road repair equipment:
  • ULTAGE® spherical roller bearings
  • self-aligning bearings (the widest range on the market of standard Asian and European sizes)
Hydraulic pumps and motors:
  • the range of tapered roller bearings in case carborised steel (including the 2 series wide-angle T7FCxxx and 303xxD)
  • the integration of encoders for the high-resolution measurement of speed

ULTAGE® spherical roller bearings can also be found in other very demanding uses of road construction equipment, such as steamrollers, vibratory plate compactors, as well as all sifting and crushing/grinding applications.
