The SKF double row angular contact deep groove ball bearing is a component designed to support radial and axial loads in both directions. Its design with two rows of angular contact balls gives it a higher load capacity than a single row bearing, while maintaining a compact section. It is ideal for applications requiring high rigidity and precision, such as machine tools, pumps and gearboxes. MR Accesorios Industriales carries this line as part of its broad offering of SKF bearings.
The designation of these bearings follows a clear system. For example, 3304 A-2ZTN9/C3VT113: the first digits indicate the size and series (33 for double row), the letter A indicates an optimized internal design, 2Z indicates two protective shields, TN9 specifies a polyamide cage, C3 is the increased internal radial clearance and VT113 corresponds to a special grease and protection. Knowing these suffixes is key to selecting the right bearing.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, food, petrochemical and cement. They are common in centrifugal pumps, compressors, industrial fans, conveyor belts and machine tools. Their ability to support combined loads and their rigidity make them suitable for equipment requiring high precision and reliability, even under demanding operating conditions.
For correct selection, take into account the radial and axial load, the rotational speed and the environmental conditions. The sealing (2Z or 2RS) protects against contaminants; choose according to exposure to dust or humidity. The internal clearance (C3, C4) compensates for thermal expansion. Proper lubrication and precise alignment of the shaft and housing are essential to maximize service life. Follow the manufacturer's recommendations for installation and lubrication.
Regarding equivalences, SKF double row angular contact bearings can be interchanged with those of other brands that follow the same dimensional and suffix designation. Always verify the tolerances and internal clearance, as they may vary between manufacturers. For replacements, it is advisable to consult a specialist who can validate compatibility and performance in the specific application.

Frequently Asked Questions
- What does the C3 suffix mean in these bearings?
- The C3 suffix indicates a greater internal radial clearance than standard. It is used when the bearing will operate at elevated temperatures or with interference fits, to compensate for expansion and avoid excessive preload.
- What is the difference between 2Z and 2RS?
- 2Z are metal protective shields, suitable for environments with coarse dust. 2RS are rubber seals, which provide better sealing against humidity and fine particles. The choice depends on the contamination conditions.
- Can I replace an SKF bearing with another brand?
- Yes, as long as the main dimensions and internal clearance match. Tolerances and materials may vary, so it is advisable to verify the equivalence with a specialist before installing.
