Radial-thrust ball bearings
Significant combined loads frequently result in premature failure of radial or thrust bearings, thereby increasing the risk of downtime and maintenance costs. NTE radial-thrust ball bearings address these issues by delivering stable operation at high rotational speeds and reducing the need for frequent maintenance.
Size range
NTE offers to buy radial-thrust ball bearings in the required size – with the necessary load capacity and rotational speed:
- Bore diameter: from 10 to 130 mm
- Outside diameter: from 30 to 230 mm
- Bearing width: from 9 to 82,6 mm
The full-size range is available in the NTE technical catalogue.
Design and operating principle
These bearings are designed to handle both radial and axial loads, eliminating the need to install two different types of bearings separately. This makes the assembly more compact, simpler, and more cost-effective.
The inner and outer rings with a special raceway profile create a contact angle of up to 40°, enabling the bearing to transmit combined loads and increase axial stiffness of the unit.
A steel, polyamide, or brass cage maintain proper ball spacing, ensuring uniform load distribution and stable operation.
These bearings are mainly manufactured in an open design without integrated seals. Protection against contamination and lubricant loss is ensured by the design of the assembly, which reduces friction, lowers cost, and simplifies maintenance.
Technical specifications
Due to optimized design and material selection, ordering radial-thrust ball bearings means ensuring reliable unit performance under a wide range of operating conditions:
- Maximum rotational speed – up to 28,000 rpm (depending on size, contact angle, and other factors).
- Operating temperature range: typically from −30°C to +120°C and determined by the type of lubricant, separator material, etc.
- Basic dynamic load rating – up to 474 kN. This ensures reliable bearing operation in power units and under peak loads.
Current values for speed, loads, and temperatures are shown in the NTE technical parameters table.
Industrial advantages
Key advantages include:
- Stable operation under combined loads – the bearing handles both radial and axial forces without premature wear.
- High rigidity and shaft positioning accuracy – ensures minimal internal clearance.
- Ability to operate at high speeds – increases equipment productivity without compromising service life.
- Long service life and low maintenance costs – less frequent bearing replacement and reduced operating expenses.
- Versatility and compatibility – standardized mounting dimensions and a wide selection of series, contact angles, materials, and accuracy classes for various industries.
Fields of application
NTE offers radial-thrust ball bearings wholesale for industries where stiffness and precision of assemblies are critical:
- Mechanical engineering – gearboxes, drive units, electric motors and generators, gear transmissions.
- Metalworking – lathes, milling and grinding machines, spindle units, feed and positioning mechanisms.
- Food industry – packaging lines, dosing equipment, and processing machines requiring accuracy and smooth motion.
- Agricultural industry – agricultural machinery and raw material processing equipment.
- Energy sector – generators, electric motors, auxiliary drives and units, centrifugal and screw pumps, compressors.
Radial-thrust ball bearings types
NTE offers all types of radial-thrust ball bearings, facilitating selection and installation.
Single-row:
- In a single row design, the load is transferred from one ring to another at an angle. As a result, radial loading generates an axial component, meaning these bearings can accommodate axial loads in one direction only.
- Paired single-row radial-thrust ball bearings are capable of accommodating axial loads in both directions. Depending on load direction and magnitude, three pairing arrangements are used: O, X, and tandem.
Double-row – provide the same characteristics as a pair of single-row bearings, but in a compact unit for easy installation.
