Spherical Roller Bearings

DESIGNED TO BEAR THE UNBEARABLE

Spherical roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks, and vibrations. And with the industry’s highest load rating and production coming from a factory near you, there’s no reason to look anywhere else for spherical roller bearings.

THE INDUSTRY’S HIGHEST LOAD RATING

NTN-SNR sphericals feature the industry’s highest load rating: a full 18% higher than a standard spherical roller bearing. This level of quality means at least a 75% extension of service life. The performance of these sphericals is achieved through the use of very high quality raw materials and optimized rolling element geometry. The unique design also leads to:

  • Reduced friction torque (as much as 30% less), offering lower operating temperature, with lower power and lubricant consumption.
  • Appreciably increased operating speed, allowing an extended scope of applications.
  • High temperature capacity of up to 200°C (392°F) for metallic cage bearings. Dimensional stability is ensured by a specific heat treatment.
  • A +/- 0.5° misalignment capability, without reducing the load capacity, and up to 1° 30’ in case of low loads.

NTN SPHERICAL ROLLER BEARINGS: RIGHT IN FRONT OF YOU ALL ALONG

Industria Cuscinetti S.P.A. (ISCA) is an Italian bearing factory that was set up as a joint venture between four bearing manufacturers, including NTN and our SNR partner brand. NTN and SNR are the majority user of ISCA’s capacity and sells the largest share of the plant’s production. That means that, even if you’ve been using spherical roller bearings from some of our competitors, it could be the same bearing made in the same plant and same equipment as what NTN offers.
