Roller thrust bearings
If you want to simplify the design of the assembly while ensuring its operation under high axial loads, consider purchasing NTE roller thrust bearings, which are an ideal universal solution.
Size range
Standard sizes and serial production allow roller thrust bearings to be used both in new machinery and for existing equipment:
- Bore diameter: from 60 to 260 mm (larger sizes on request)
- Outside diameter: from 130 to 480 mm
- Bearing width: from 39 to 132 mm
Design and operating principle
All NTE roller thrust bearings feature a standardized base architecture in accordance with ISO requirements and consist of the following components:
- Shaft washer – fixed on the shaft and absorbs axial loads.
- Housing washer (one or two, depending on load direction) – has clearance between its inner diameter and the shaft and transfers axial load to the housing.
- Steel or brass cage – ensures smooth rolling. Steel cages are typically window-type, while brass cages are machined and comb-shaped.
- Cylindrical or tapered rollers – in tapered designs, the roller generatrices intersect at a single point on the bearing axis, minimizing sliding during rotation.
All parts are installed separately during assembly, allowing the condition of the bearing to be monitored, wear to be checked, and defects to be detected before an emergency stop.
Technical specifications
NTE bearings are designed with key technical parameters in mind:
- Maximum rotational speed – up to 2,800 rpm with good lubrication.
- Operating temperature range – from -30°C to +120°C.
- Basic dynamic load rating – up to 4,400 kN.
Industrial advantages
The products comply with the international ISO standard. This means you can buy roller thrust bearings, interchangeable with other brands.
The reliability of industrial equipment is enhanced by the following factors:
- Increased load capacity compared to ball bearings – reduces wear on parts.
- Compensation of angular misalignment when spherical thrust designs are used – extends service life.
- Uniform load distribution across the raceways – reduces contact stresses and increases bearing durability
Fields of application
Roller thrust bearings are particularly relevant for enterprises operating in heavy industry, metallurgy, and mining:
- High-power turbines and electric motors.
- Pressing and stamping equipment.
- High-pressure compressors and pumps.
- Rolling mills.
- Converters and blast furnaces.
- Crushers and metal-processing rollers.
- Conveyor gearboxes.
- Drilling and quarry machinery.
Roller thrust bearings types
In addition to thrust bearings with cylindrical or tapered rollers, NTE also offers spherical thrust bearings. This design is intended to accommodate large axial loads and, at the same time, small radial loads (up to 0.5 axial).
A spherical raceway on the housing washer allows the bearing to self-align and compensate for misalignment of 1–3°. The rollers feature a specially designed asymmetric profile that reduces edge stresses and ensures uniform load distribution.
The cage, usually made of brass, holds the rollers in the correct position, ensuring their even distribution around the inner ring. This reduces friction between the rolling elements.
However, it should be noted that thrust roller bearings are primarily designed to withstand axial loads. Their speed is low. Therefore, for high axial loads and higher rotation speeds, it is better to use tapered roller bearings.
Why choose NTE
- Stable supply – reduced waiting times.
- Quality assurance – certified products and multi-stage inspection.

Designations and dimensions
Spherical roller thrust bearings carry very heavy axial loads together with moderate radial loads, and their self-aligning design compensates for shaft misalignment. NTE offers them with bore diameters from 60 to 260 mm in light, medium and heavy series.
