Decoding SKF 2206 E-2RS1KTN9
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- E-2RS1KTN9Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2206 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2206 E-2RS1KTN9 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 20 mm (30 x 62 x 20 mm).

When a shaft deflects or the housing is not perfectly aligned, a self-aligning ball bearing keeps the assembly running. The SKF series 22 design uses two rows of balls and a spherical raceway in the outer ring, so the bearing compensates for angular misalignment between shaft and housing. Typical places you find them are transmissions, fans and process equipment. MR Industrial Accessories supplies this line and helps you sort out which variant fits your application.
Reading the code is the fastest way to know what you are ordering. Take 2205 as the base number: 22 is the dimension series and 05 is the size code. A suffix E means the internal design was optimized for higher load capacity. Then 2RS1 tells you there are rubber contact seals on both sides, keeping lubricant in and contaminants out. K is a tapered bore with a 1:12 taper, and TN9 is a ball-centered cage in glass fiber reinforced polyamide. Put together, a 2205 E-2RS1KTN9 is a sealed self-aligning ball bearing with tapered bore and polyamide cage.
You will see these bearings wherever misalignment or shaft deflection is part of normal operation: conveyors, industrial fans, centrifugal pumps, textile machines, bottling lines and belt drives. They also show up in food, chemical and cement plants and in water treatment facilities. Mounted in split plummer block housings or on long shafts that bend under load, the self-aligning behavior cuts wear and keeps the assembly in service longer.
Selection starts with the seal. 2RS1 is a contact seal, a good fit for dusty or humid surroundings. If speed is the priority, look at a version without seals or with non-contacting seals instead. A tapered bore (K) needs the right adapter sleeve and a controlled fit so internal clearance comes out correct. Sealed versions come lubricated for life; on open versions, the lubricant has to be chosen based on temperature and speed. Thanks to the self-aligning design, initial alignment is not critical, but it is worth confirming the misalignment angle stays within the permissible limits.
On equivalents: series 22 self-aligning ball bearings follow international standards, so products from different brands interchange in dimensions and load capacity. When replacing one, compare the complete designation, meaning series, seal suffixes, bore type and cage. Not every combination is offered by every brand, and an open bearing is not a direct swap for a sealed one in a contaminated environment. MR Industrial Accessories can point you to the options available in its line.

Frequently asked questions
- SKF 2206 E-2RS1KTN9 bearing: what are its dimensions?
- SKF 2206 E-2RS1KTN9 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 20 mm (30 x 62 x 20 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2206.
- What does the K suffix mean on a self-aligning ball bearing?
- K marks a tapered bore with a 1:12 taper. The bearing can then be mounted on a tapered shaft or with an adapter sleeve, which gives a more precise fit and makes disassembly easier.
- Are 2RS1 seals suitable for high speeds?
- 2RS1 seals are contact seals. They protect very well against dust and humidity, but they do add friction. For high speeds, consider variants with non-contacting seals or open bearings with the right lubrication.
- How do I know if a self-aligning ball bearing from another brand is equivalent?
- Compare the complete designation: base number, seal suffixes, bore type and cage. When those match, dimensions and load capacity are usually interchangeable. If you are unsure, send us the original code.
