Description
FAG QJ1038-N2-MPA is a angular contact ball bearing reference, within Bearings. Request a quote for QJ1038-N2-MPA via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The four-point bearing is a single-row angular contact bearing that can support axial loads in both directions as well as radial loads. Its design with a split outer ring and large balls allows it to replace combinations of two bearings in a single support. It is used in applications where space is limited and high load capacity and rigidity are required, such as gearboxes, machine tools and lifting equipment.
The designation of this series reads as follows: the letters QJ identify the four-point series; the number that follows indicates the size, and the suffixes provide construction details. For example, in QJ219-N2-MPA, the 219 corresponds to the size, N2 indicates two slots in the outer ring, and MPA indicates that the cage is machined brass, ball-centered. Other examples such as QJ220-N2-MPA or QJ230-N2-MPA share the same structure, varying only in size. Knowing these suffixes allows you to quickly identify the characteristics of each variant.
In Argentine industry, these bearings are found in gearboxes and gear cases, machine tool spindles, lifting and transport equipment, and in applications where a support that withstands axial loads in both directions with a single bearing is needed. They are also used in large pumps and in machinery for the food and chemical industries, where precision and load capacity are critical. MR Accesorios Industriales supplies this line to serve different productive sectors in the country.
To correctly select a four-point bearing, take into account the axial and radial load it must support, the rotation speed and the environmental conditions. Sealing or additional protections are important if there are contaminants. During mounting, it is essential to align the rings and apply the appropriate preload according to the equipment design. Lubrication must be chosen based on temperature and speed; incorrect lubrication can reduce service life. If you have doubts, consult us with the part number and the context of use.
Four-point bearings can be interchanged between brands if the main dimensions and load capacities match. However, internal suffixes, such as cage type or slots, may vary between manufacturers. Therefore, when replacing a bearing, verify not only the basic part number but also the complete specifications. At MR Accesorios Industriales we can advise you on the appropriate equivalent according to the part number you send us.

Frequently Asked Questions
- What does the N2 suffix mean in a four-point bearing?
- The N2 suffix indicates that the bearing has two slots in the outer ring. These slots allow lubricant entry or facilitate mounting in certain configurations. It is a construction detail that can influence the application, so it is advisable to verify that it is the right one for your equipment.
- Can I replace a four-point bearing with two angular contact bearings?
- In some cases it is possible, but not always. The four-point bearing takes up less axial space and can support loads in both directions. If the original design uses only one, replacing it with two may require modifications. Consult us with the part number and load conditions to evaluate the best option.
- How do I know if the four-point bearing is the right one for my application?
- Evaluate the axial and radial loads, speed, temperature and environment. Also consider the available space and required rigidity. If you send us this data along with the part number, we can advise you. The correct selection ensures reliable performance and longer service life.
