Decoding SKF 2202 E-2RS1TN9/W64
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 02Bore
- Bore 15 mm: by standard, 02 designates 15 mm.
- E-2RS1TN9/W64Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2202 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2202 E-2RS1TN9/W64 measures 15 mm across the bore and 35 mm across the outside diameter; its width is 14 mm (15 x 35 x 14 mm).

Series 22 self-aligning ball bearings from SKF are double-row units whose outer ring features a spherical raceway. This design lets the bearing compensate for small angular misalignments between shaft and housing, which is useful when shaft deflection or mounting inaccuracies are present. They run with low friction and are suited to high-speed operation.
The part number tells you what you are getting. The basic number, such as 2202 or 2207, sets the size and dimension series. An E suffix means the internal design has been optimized for higher load capacity. 2RS1 indicates rubber seals on both sides, keeping lubricant in and contaminants out. TN9 is a glass fiber reinforced polyamide cage, which is lightweight and resistant. /W64 points to a special lubrication for particular conditions. Together, these suffixes describe a sealed bearing intended for maintenance-free use.
These bearings are found in transmission equipment, fans, centrifugal pumps, conveyors and agricultural machinery. Their self-aligning ability is valuable on long shafts or shafts that bend, where a rigid bearing would introduce parasitic loads. They are also selected for vibrating applications or where the mounting structure may deform. Because they are sealed, they handle dusty or moderately humid environments, as long as they are not submerged.
Selection depends on radial and axial load, rotation speed and shaft diameter. Make sure the housing permits self-alignment: the outer ring must be free to move angularly. During mounting, do not strike the seals and keep shaft and housing clean. The /W64 suffix defines the lubrication; do not mix it with other greases. At high speed, confirm that the polyamide cage suits the operating temperature.
When replacing, self-aligning ball bearings from different brands with the same basic designation usually interchange in dimensions and load capacity. Suffixes, however, can differ: a 2RS seal from one maker may correspond to 2RS1, 2RSR or similar in another. Do not assume suffixes are identical; check the manufacturer's specifications. MR supplies SKF as a brand and can advise on a suitable equivalent for your equipment.

Frequently asked questions
- SKF 2202 E-2RS1TN9/W64 bearing: what are its dimensions?
- SKF 2202 E-2RS1TN9/W64 measures 15 mm across the bore and 35 mm across the outside diameter; its width is 14 mm (15 x 35 x 14 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2202.
- What does the suffix 2RS1 mean on an SKF bearing?
- 2RS1 means the bearing has rubber seals on both sides. These seals retain grease and block dust and moisture, so the bearing is factory-lubricated and needs no additional maintenance.
- Can I replace an SKF self-aligning ball bearing with another brand?
- Usually yes, if the main dimensions and load capacity match. But suffixes can change between manufacturers. Verify that sealing, cage and lubrication are equivalent so performance is not compromised.
- 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.
