How to read SKF 2202 E-2RS1TN9/W64
- 22Series
- Self-aligning ball bearings, 22 series. For the same bore, each series has a different outside diameter and width.
- 02Bore
- 15 mm bore: code 02 stands for 15 mm by standard.
- E-2RS1TN9/W64Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
2202 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF self-aligning ball bearings of series 22 are double-row ball bearings with a spherical raceway in the outer ring. This configuration allows them to self-align and accommodate small angular misalignments between shaft and housing. They are used in applications where shaft deflection or mounting errors are unavoidable, and where low friction and high speed are required.
The designation of these bearings reads as follows: the basic number, for example 2202 or 2207, indicates the size and dimension series. The suffix E denotes an optimized internal design with higher load capacity. 2RS1 corresponds to rubber seals on both sides, which retain lubricant and block contaminants. TN9 identifies a glass fiber reinforced polyamide cage, lightweight and resistant. /W64 indicates a special lubrication for specific conditions. This combination of suffixes defines a sealed bearing, ready for maintenance-free applications.
In Argentine industry, these bearings appear in transmission equipment, fans, centrifugal pumps, conveyors and agricultural machinery. Their self-aligning capability makes them useful on long shafts or shafts subjected to bending, where a rigid bearing would generate parasitic loads. They are also chosen in applications with vibration or mounted on structures that may deform. Being sealed, they are suitable for environments with dust or moderate humidity, provided there is no immersion.
To select correctly, take into account radial and axial load, rotation speed and shaft diameter. Verify that the housing allows self-alignment: the outer ring must be able to move angularly. During mounting, avoid striking the seals and make sure the shaft and housing are clean. Lubrication is defined by the suffix /W64; do not mix it with other greases. If the bearing rotates at high speed, check that the polyamide cage is compatible with the working temperature.
When replacing, self-aligning ball bearings from different brands with the same basic designation are usually interchangeable in dimensions and load capacity. However, suffixes may vary between manufacturers: a 2RS seal from one brand may be equivalent to 2RS1, 2RSR or similar in another. Do not assume that all suffixes are identical; always verify the manufacturer's specifications. At MR Accesorios Industriales we sell SKF as a brand and can advise you on the appropriate equivalent for your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF 2202 E-2RS1TN9/W64 bearing?
- The SKF 2202 E-2RS1TN9/W64 bearing has a 15 mm bore, a 35 mm outside diameter and a 14 mm width (15 x 35 x 14 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2202.
- What does the suffix 2RS1 mean on an SKF bearing?
- 2RS1 indicates that the bearing has rubber seals on both sides. These seals retain grease and prevent the entry of dust and moisture, so the bearing is factory-lubricated and requires no additional maintenance.
- Can I replace an SKF self-aligning ball bearing with another brand?
- In general, yes, if the main dimensions and load capacity match. But suffixes may change between manufacturers. It is important to verify that the sealing, cage and lubrication are equivalent so as not to compromise performance.
- Where are series 22 self-aligning ball bearings used?
- They are used in equipment with shafts that may bend or misalign, such as fans, pumps, conveyors and agricultural machinery. Their self-aligning capability reduces parasitic stresses and extends the service life of the assembly.
