JFK ball bearings
Versatile, reliable, for every operating condition
Radial, thrust, self-aligning, and angular contact bearings: the complete range for supporting rotating shafts.
Ball bearings are rolling bearings in which the rolling elements are balls positioned between the inner and outer rings, supporting radial and axial loads at high speeds with low friction. JFK ball bearings cover the full range of industrial applications: from deep groove ball bearings for combined loads at high speeds, to thrust ball bearings for pure axial loads, self-aligning ball bearings for compensating misalignment, and angular contact ball bearings for high axial loads. The range is completed by cam rollers and Agri Hub units for demanding agricultural applications. Every product is selected to ensure verified quality, availability, and technical support at every stage of the project.

Radial, thrust, self-aligning: eight types, countless applications
The eight types in this range differ in internal design, load direction, and application range. Deep groove ball bearings are the most versatile choice for combined loads and high speeds. Angular contact ball bearings excel when axial load is predominant or high axial stiffness is required. Self-aligning ball bearings tolerate angular misalignment without compromising performance. Thrust bearings are dedicated to purely axial loads. High-temperature and stainless-steel bearing versions cover the most demanding environmental conditions. Cam rollers and Agri Hub units complete the range for specific applications on guides and agricultural machinery.
JFK thrust ball bearings

JFK Agri Hub
Integrated units · Ready to install · Maintenance-free · Maximum protection Integrated units with angular contact ball bearings and an advanced sealing system. Designed for disc harrows, seed drills, and agricultural machinery exposed to dust, mud, and impact.SELECTION GUIDE
Start by identifying the operating conditions
JFK ball bearings cover a wide range of applications: from purely radial loads to high axial loads, from applications involving misalignment to those requiring high speeds and low noise levels. Start with the operating condition that best describes your application.
Combined loads at high speeds
Deep groove ball bearings are the ideal solution: deep raceways, low internal friction, and availability in shielded or sealed, lifetime-lubricated versions. The most widely used choice for motors, pumps, and general-purpose applications. Predominantly axial or bidirectional loads
When the axial load exceeds the radial load or acts in both directions, angular contact ball bearings are the solution. A 40° contact angle provides high axial load capacity, while paired mounting accommodates axial loads in both directions. Alignment errors or shaft deflection
Self-aligning ball bearings compensate for angular misalignment without compromising performance, thanks to the spherical raceway on the outer ring. Among all rolling bearings, they feature the lowest internal friction. Available with a tapered bore for quick installation on the shaft. Extreme temperatures, moisture, food-processing environments, or chemically aggressive conditions
For temperatures up to +330°C, high-temperature bearings are the preferred choice. In humid, chemical, or food-processing environments, the AISI 316 stainless steel version provides corrosion resistance without compromising performance.Contacts
