How to read SKF 2212 E-2RS1KTN9
- 22Series
- Self-aligning ball bearings, 22 series. For the same bore, each series has a different outside diameter and width.
- 12Bore
- 60 mm bore: 12 × 5.
- E-2RS1KTN9Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
2212 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The SKF self-aligning ball bearing from the 22 series is a ball bearing with two rows and a spherical raceway in the outer ring, which allows it to self-align and compensate for angular misalignment between shaft and housing. It is used in applications where shaft deflection or mounting errors are unavoidable, such as transmissions, fans or process equipment. MR Accesorios Industriales sells this line with technical advice to choose the right variant.
The designation of these bearings is read in blocks: the base number, for example 2205, indicates the dimension series (22) and the size code (05). The suffix E indicates an optimized internal design, with higher load capacity. Then, 2RS1 corresponds to rubber contact seals on both sides, which retain lubricant and block contaminants. The K indicates a tapered bore (1:12 taper), and TN9 identifies the glass fiber reinforced polyamide cage, ball-centered. Thus, a 2205 E-2RS1KTN9 is a sealed self-aligning ball bearing with tapered bore and polyamide cage.
These bearings are used in equipment where there is misalignment or shaft deflection: conveyors, industrial fans, centrifugal pumps, textile machines, bottling equipment and belt drives. In Argentina, they are found in the food, chemical and cement industries and in water treatment plants. Their self-aligning ability reduces wear and extends service life in assemblies with split plummer block housings or on long shafts that deflect under load.
To select correctly, take into account the type of seal: 2RS1 is contact, ideal for environments with dust or humidity; if the speed is high, a variant without seals or with non-contacting seals may be preferable. The tapered bore (K) requires a suitable adapter sleeve and controlled fit to achieve the correct internal clearance. Factory lubrication is for life in the sealed versions; in open versions, the lubricant must be defined according to temperature and speed. Initial alignment is not critical thanks to the self-aligning design, but it is advisable to verify that the misalignment angle does not exceed the permissible limits.
As for equivalents, self-aligning ball bearings from the 22 series are manufactured under international standards, so different brands offer products interchangeable in dimensions and load capacity. When looking for a replacement, always compare the full designation: series, seal suffixes, bore type and cage. Not all combinations exist in all brands, and an open variant is not a direct replacement for a sealed one if the environment is contaminated. MR Accesorios Industriales can guide you on the options that apply in its product line.

Frequently Asked Questions
- What are the dimensions of the SKF 2212 E-2RS1KTN9 bearing?
- The SKF 2212 E-2RS1KTN9 bearing has a 60 mm bore, a 110 mm outside diameter and a 28 mm width (60 x 110 x 28 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2212.
- What does the K suffix mean on a self-aligning ball bearing?
- The letter K indicates that the bearing has a tapered bore with 1:12 taper. This allows it to be mounted on a tapered shaft or with an adapter sleeve, achieving a more precise fit and facilitating disassembly.
- Are 2RS1 seals suitable for high speeds?
- 2RS1 seals are contact seals and offer very good protection against dust and humidity, but they generate some friction. For high speeds, evaluate variants with non-contacting seals or open bearings with suitable lubrication.
- How do I know if a self-aligning ball bearing from another brand is equivalent?
- Compare the full designation: base number, seal suffixes, bore type and cage. If they match, dimensions and load capacity are usually interchangeable. If in doubt, consult us with the original code.
