Decoding SKF 2212 EKTN9
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- EKTN9Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2212 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 2212 EKTN9 measures 60 mm across the bore and 110 mm across the outside diameter; its width is 28 mm (60 x 110 x 28 mm).

When shafts and housings don't line up perfectly, SKF self-aligning ball bearings with the EKTN9 suffix keep things running. These bearings have a spherical outer ring and two rows of balls, so they handle angular misalignment. You'll find them in fans, pumps, conveyors and other power transmission setups.
The part number tells you a lot. Take 1205: the first two digits give the diameter series, the last one the bore size. Then EKTN9 adds the details. E means a lubrication groove in the outer ring. K means a tapered bore, 1:12. TN9 means a polyamide cage reinforced with fiberglass. So a 1205 EKTN9 is a self-aligning bearing with tapered bore and polyamide cage, ready for an adapter sleeve.
These bearings show up in many places. Fans and blowers often use them because loads are moderate and slight misalignment can happen. You'll also see them in centrifugal pumps, conveyors, textile machines and belt drive equipment. Their ability to self-align helps when the shaft flexes or the supports aren't machined perfectly. Food, chemical and process industries rely on them for their robustness and easy maintenance.
When you pick an SKF EKTN9 bearing, think about load and speed. The tapered bore lets you mount it with an adapter sleeve, which makes adjustment and disassembly easier. The TN9 polyamide cage works well at moderate temperatures and resists fatigue. Lubrication matters: the E groove lets you grease through the outer ring. Check alignment at the start, even though the bearing compensates, it's not unlimited. Sealing depends on the environment; in dirty spots, add shields.
For equivalents, other brands offer self-aligning bearings with similar suffixes, but cage materials, tolerances and load capacity can differ. When replacing, don't just match the basic number. Make sure the suffix matches for bore type, cage and lubrication. SKF designations are widely recognized, which helps with interchangeability. If you're unsure, ask a specialist before substituting.

Frequently asked questions
- SKF 2212 EKTN9 bearing: what are its dimensions?
- SKF 2212 EKTN9 measures 60 mm across the bore and 110 mm across the outside diameter; its width is 28 mm (60 x 110 x 28 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2212.
- What does the EKTN9 suffix mean on an SKF bearing?
- E is for a lubrication groove in the outer ring, K for a tapered bore (1:12) and TN9 for a polyamide cage reinforced with fiberglass. These suffixes tell you about mounting and lubrication.
- Does this bearing allow misalignment?
- Yes, self-aligning ball bearings compensate for angular misalignment between shaft and housing. That makes them useful when precise alignment is hard to keep, like with flexible shafts or supports that aren't perfectly machined.
- How is a bearing with a tapered bore mounted?
- It mounts with an adapter sleeve, which makes adjustment and disassembly easier. Follow the manufacturer's instructions for correct tightening to avoid damage. The taper is 1:12.
