Spherical roller bearings designed
to last
A complete range for demanding applications
The NTN range of spherical roller bearings offers high performance, even in the most severe environments: heavy loads, misalignment, temperatures up to 200°C, pollution, etc.
Designed and manufactured in our modern factories in Italy and Japan, these bearings incorporate :
- high-quality steel
- optimised roller sizes
- optimised surface finishes
- reinforced cages in pressed steel or high-performance solid brass without a central guide ring
- specific heat treatments
- to guarantee robustness, dimensional stability and wear resistance.
Their improved design enables higher speeds, reduces operating temperatures and extends maintenance intervals. Standard, sealed or customised, they can be adapted to meet every need with reliability and efficiency.

Spherical roller bearings to suit every need
Standard (SRB)
Proven quality for lasting performance
The basic version without sealing. It offers an excellent performance/cost compromise for applications with little exposure to contamination. Easy to integrate, it's the ideal solution for clean environments or regular maintenance.
Sealed (SSRB)
Performance against pollution and infiltration
Equipped with a specially designed nitrile seal, these bearings provide a reliable seal even in the event of misalignment. Their internal design and load ratings are identical to the open versions. Pre-greased for operation at temperatures up to 70°C, they offer extended service life and greatly reduce maintenance requirements.
With metalic deflectors (Kizei)
Armoured to face the dirt.
The bearing offers exceptional durability thanks to its nitrided metal deflectors, guaranteeing resistance to impact and corrosion. Easy to fit and interchangeable with standard bearings, it reduces maintenance costs while ensuring reliable performance in demanding conditions.
Series EF800
The reinforced cage for vibratory applications
Designed for vibrating machines, the EF800 series incorporates a solid machined brass cage, with no guide ring or central shoulder, to avoid any risk of jamming. Its reduced radial clearance and specific tolerances ensure reliability, longevity and extended maintenance intervals.
Thrust
Maximum performance, even in the most extreme conditions
Designed for high axial loads, spherical roller thrust bearings are ideal for heavy environments such as presses, cranes, turbines and mining equipment. Interchangeable (ISO), they guarantee robustness with their sheet steel cage and allow a radial load of up to 50% of the axial load.
Spherical roller bearings with metal deflectors
It combines robustness, reliability and ease of integration. Its integrated metal seal provides long-lasting protection for equipment, with no need for design modifications or special housing. An ideal solution for dusty, damp or difficult-to-access environments.
- High-quality nitrided metal cage and baffles
- Interchangeable: Compatible with standard spherical roller bearings (SRB)
- Extended service life: up to 3 times longer service life
- Reduced maintenance costs: greasing frequency reduced by a factor of 3
- Extended temperature range: up to +200°C.
- Simple installation: no special tools required
- Simplified lubrication: similar process to open bearings
Designed to perform in demanding environments
