The FAG four-point bearing is an angular contact ball bearing designed with a split outer race. This configuration allows a single row of balls to operate with two opposing contact points, enabling the bearing to handle radial loads, axial loads in both directions, and moments. It is commonly chosen for applications where combined forces and rigidity are required.
The QJ prefix denotes the four-point bearing family. The digits that follow indicate the size: in QJ315, QJ1017, QJ1019, and QJ1021, the first two digits specify the dimension series and the remaining digits give the bore diameter. Suffixes such as XL, N2, and MPA identify the generation, grooves, or cage design. Always refer to the complete code when specifying a bearing.
Typical uses include machine tools, spindles, gearboxes, lifting equipment, and mechanisms where load direction changes. These bearings also suit precision assemblies that need to absorb axial forces in both directions without an additional bearing. Their moment capacity helps simplify units where space is limited.
When selecting a four-point bearing, evaluate radial and axial loads, rotation speed, and required rigidity. Proper mounting demands good alignment of the supports and control of internal clearance, as the split race is sensitive to mounting errors. Lubrication must match the temperature and speed, often with a high-quality grease. Sealing depends on the environment; in dusty or moist conditions, the bearing should be protected.
Four-point bearings from different brands can be interchanged if the main dimensions and race design match. Equivalences are based on catalogue number and suffixes, but manufacturers may differ in cages or tolerances. Before replacing a bearing, verify the complete code and operating conditions. MR Industrial Accessories can help you find the right equivalent.

Frequently asked questions
- What does QJ indicate in a FAG bearing?
- QJ is the designation for FAG four-point bearings. It signifies a ball bearing with a split outer race that supports axial loads in both directions and moments. The following number identifies the size.
- How do I choose the right suffix for my application?
- Suffixes like XL, N2, or MPA denote design features such as generation, grooves, or cage type. The choice depends on load, speed, and environment. If unsure, send us the complete code and we will advise.
- Can this bearing replace two thrust bearings?
- In some assemblies, a four-point bearing can replace two thrust bearings because it supports loads in both directions. However, load capacity and rigidity must be verified. Contact us about your specific case.
