The SKF 2304 TN self-aligning ball bearing is a double row ball bearing with a spherical raceway in the outer ring, designed for shafts where the alignment between housing and shaft is not perfect. It is used in equipment with shaft deflection, assemblies on stamped steel plate or split housings, and in general in applications where it is convenient to absorb small misalignments without losing load capacity.
The designation of this family is read in parts: the numeric prefix identifies the series and the bore size, and the final letters distinguish the bearing execution. In the 2304 series, the complete code is 2304 TN: the first two digits indicate the series and the next two the bore, while TN accompanies the number as part of the execution. To order another size of the same family, provide the complete code exactly as it appears on the drawing or on the equipment nameplate.
In Argentine industry, these bearings appear in conveyors, screens, mixers, fans, food machinery and process equipment where the shaft works with some deflection or the housing is not perfectly aligned. They are also found in agricultural implements, pumps and low-demand gearboxes, and in general in any assembly where the seat is not rigid and it is convenient for the bearing to follow the shaft movement.
To select and mount a self-aligning bearing, take into account the diameter and tolerances of the shaft and housing, the type of load and the working conditions. Lubrication, sealing and the initial alignment of the assembly are key to performance: verify that the housing allows the self-aligning movement and that the shaft is not forced. If the equipment works with vibration or dirt, it is advisable to check the assembly and the condition of the housings.
Between brands, self-aligning bearings are interchanged by series number and bore size: the same code may appear with different final letters depending on the manufacturer, and those letters change the execution. If you bring the code of another brand or an unidentified part, at MR Accesorios Industriales we will indicate the compatible equivalence and quote the replacement you need.

Frequently Asked Questions
- What are the dimensions of the SKF 2304 TN bearing?
- The SKF 2304 TN bearing has a 20 mm bore, a 52 mm outside diameter and a 21 mm width (20 x 52 x 21 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2304.
- What applications does the 2304 TN self-aligning ball bearing have?
- It is used in equipment where the shaft can deflect or the housing is not perfectly aligned: conveyors, screens, mixers, fans and process machinery. Also in agricultural implements and pumps. Self-alignment helps compensate for small assembly deviations.
- How do I request a different size of the 2304 series?
- Send via WhatsApp the complete code that appears on the equipment or on the drawing, for example 2304 TN, and we will quote it. If you have the shaft size and the type of load, that also helps us guide you on the equivalent designation.
- What should I check before mounting a self-aligning ball bearing?
- Check the diameter and tolerances of the shaft and housing, the lubrication and the condition of the housings. Make sure the housing allows self-alignment and that the shaft is not forced. If there is vibration or dirt, check the sealing of the assembly.
