Radial ball bearings
NTE radial ball bearings are designed to ensure smooth, precise, and trouble-free operation of your mechanisms. They can withstand high radial and partial axial loads, minimizing friction and heat generation for maximum service life. These components are easy to integrate into a wide range of industrial applications. Their reliability provides long-lasting and stable operation of equipment when selected and operated correctly.
Size range
The portfolio includes a full range of dimensional variations, allowing you to order radial ball bearings for small and medium mechanisms as well as for heavy-duty industrial equipment:
- Bore diameter: from 10 to 1400 mm
- Outside diameter: from 26 to 1700 mm
- Bearing width: from 8 to 132 mm
Such a wide selection enables not only the design of new equipment in line with modern requirements and loads, but also the effective maintenance and modernization of existing systems.
The full-size range is available in the NTE technical catalogue.
Design and jperating principle
The outer and inner rings of NTE bearings are processed to ensure smooth and stable ball movement, while high-quality bearing steel provides strength, wear resistance, and load capacity. High-quality material, optimal geometry of elements, and a contact angle of 15°-25° reduce friction and ensure smooth rotation, allowing mechanisms to operate accurately and without failure.
Additional operational reliability is achieved through cage options:
- Stamped cages – minimal friction and stability at moderate speeds.
- Polyamide cages – lightweight, quiet, and wear-resistant, ideal for high-speed assemblies.
- Brass cages – for large bearings or assemblies with increased loads.
Cages maintain proper ball spacing and ensure even load distribution. Their material choice significantly affects the radial bearings price.
For operation in aggressive environments – such as dust, water, or chemicals – we suggest bearings with seals or washers on one or both sides. They extend service life and reduce maintenance costs.
Technical specifications
In industrial applications, bearing overheating can cause equipment to shut down. Therefore, NTE offers options for different operating conditions and loads:
- Maximum rotational speed – up to 130,000 rpm (depending on bearing size, lubricant type, and operating conditions).
- Operating temperature range – typical sealed bearings usually operate in the standard industrial range of -30 to +120 °C.
- Basic dynamic load rating – from 0.54 kN for small bearings to 1,210 kN for large bearings.
Current values for speed, loads, and temperatures are shown in the NTE technical parameters table.
Industrial advantages
NTE radial ball bearings are capable of withstanding not only normal radial loads, but also axial forces up to 50% of their basic load capacity. This ensures stable and failure-free operation even under shaft misalignment or combined load conditions.
These characteristics provide ball radial bearings with the following advantages:
- Versatility of application – a wide range of designs suitable for various mechanisms and operating environments.
- Smooth and efficient operation – low noise and vibration, smooth rotation, reduced heat generation, and increased equipment productivity.
- Ease of installation and maintenance – standardized dimensions allow replacement or upgrades without modifying equipment design.
Due to the versatility of the design, this type is relevant for both mass production and maintenance. Therefore, it is quite reasonable to buy radial ball bearings wholesale – without the risk of excess inventory remaining unused.
Fields of application
They are used almost everywhere where there are rotating assemblies and mechanisms:
- Electric motors, gearboxes, and drive systems.
- Pumps and compressors.
- Agricultural machinery (harvesters, balers, conveyors).
- Machine tools and spindle units.
- Conveyor lines and transport systems.
- Ventilation and air-conditioning equipment.
Radial ball bearings types
Many series are manufactured in higher precision classes – P6, P5, and sometimes P4 – for precision mechanisms. This guarantees minimal clearance, smooth running, and positioning accuracy. However, bearing performance also depends on the specific type:
- Single-row open bearings – lighter and quieter due to minimal friction; ideal for clean environments where precision and smooth movement are important.
- Single-row sealed bearings – supplied fully lubricated, require no maintenance throughout their service life, and perform well in contaminated environments.
- Double-row bearings – double strength for mechanisms: more balls mean greater resistance to loads and maximum stability even with shaft misalignment up to 2.5°.
