How to read SKF 4314 ATN9
- 43Series
- Double row ball bearings, 43 series. For the same bore, each series has a different outside diameter and width.
- 14Bore
- 70 mm bore: 14 × 5.
- ATN9Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
4314 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF double row deep groove ball bearings are components designed to withstand radial and axial loads in both directions. Their two-row ball construction offers greater load capacity than a single row bearing of the same size, while maintaining a compact design. They are used in applications requiring rigidity and precision, such as machine tools, pumps and gearboxes. At MR Accesorios Industriales we sell products so you can choose the right part number for your equipment.
The designation of these bearings combines a four-digit number with the suffix ATN9. The base number identifies the size and series: for example, 4200 ATN9, 4201 ATN9 and 4202 ATN9 correspond to increasing bore diameters within the same category. The suffix ATN9 indicates a glass fiber reinforced polyamide cage, suitable for moderate temperatures and applications where weight and noise reduction are sought. Knowing this nomenclature allows you to order the exact replacement without ambiguity.
These bearings are used in industries such as food, chemical, petrochemical and process industries in Argentina. Equipment such as centrifugal pumps, fans, small compressors, mixers and conveyors benefit from their ability to withstand combined loads. They also appear in packaging equipment and precision machine tools, where the double row provides rigidity and smooth operation. Their sealed or open design, depending on the variant, allows them to be adapted to dusty or humid environments.
To select the correct bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. Check the sealing type: versions with rubber seals protect better against contaminants, while open ones facilitate lubrication. During assembly, ensure precise alignment between shaft and housing, and apply the lubrication recommended by the manufacturer. Incorrect fitting can reduce bearing life and generate vibrations.
Regarding equivalences, SKF double row bearings can be interchanged with those of other brands that follow the same dimensional and suffix designation. Always verify that the complete part number matches in bore, outer diameter and width, as well as the cage type. If in doubt, ask us with the original part number and we will help you find the right option. Interchangeability between brands is possible when tolerances and internal design are respected.

Frequently Asked Questions
- What are the dimensions of the SKF 4314 ATN9 bearing?
- The SKF 4314 ATN9 bearing has a 70 mm bore, a 150 mm outside diameter and a 51 mm width (70 x 150 x 51 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 4314.
- What does the ATN9 suffix mean in these bearings?
- The ATN9 suffix indicates that the bearing has a glass fiber reinforced polyamide cage. This cage is lightweight, resistant and suitable for applications with moderate temperatures. It does not change the external dimensions or load capacity, but it influences dynamic behavior and heat dissipation.
- How do I choose between a single row and a double row bearing?
- The choice depends on the load and available space. Double row bearings withstand higher radial and axial loads in both directions, but they take up more width. If your application has significant combined loads or you need greater rigidity, the double row is the option. Ask us with your working conditions.
- Can I replace an SKF bearing with another brand?
- Yes, as long as the main dimensions (bore, outer diameter and width) and the cage type match. International standards guarantee dimensional interchangeability. We recommend also verifying load capacity and service conditions. If you send us the original part number, we will advise you on the equivalence.
