- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 09Bore
- Bore 45 mm (09 × 5).
- K-TVH-C3Suffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2209 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

The FAG self-aligning ball bearing 1204-K-TVH-C3 is a two-row bearing that compensates for angular misalignment between shaft and housing. Its spherical outer raceway lets the inner ring tilt, so mounting is easier and alignment errors are absorbed. It suits setups where the shaft flexes or the support lacks rigidity.
Reading the code helps you order the right variant. The base number 1204 sets the size, K means a tapered bore for mounting on a tapered shaft, TVH identifies a fiberglass-reinforced polyamide cage, and C3 denotes increased internal radial clearance. The same pattern applies to 1205-K-TVH-C3, 1206-K-TVH-C3 and 1207-K-TVH-C3.
These bearings are common in belt conveyors, textile machines, bottling equipment, fans and mixers. They also appear on long transmission shafts where flex demands self-alignment. With two rows of balls, they carry moderate radial and axial loads in both directions, which makes them a frequent choice in food, chemical and process plants.
Selection depends on the bore type. A K series bearing mounts on a tapered shaft, usually with an adapter sleeve, which simplifies radial clearance adjustment. The TVH cage handles moderate temperatures and standard lubrication. C3 clearance is recommended with interference fits or thermal gradients. Check initial alignment and pick the lubricant for the service conditions.
Self-aligning ball bearings can be interchanged between manufacturers when main dimensions, bore type and clearance match. A part number with K and C3 from another brand may replace the FAG one if those characteristics are kept. Tolerances and cage materials can differ, so confirm the equivalence with a specialist before ordering.

Frequently asked questions
- FAG 2209-K-TVH-C3 bearing: what are its dimensions?
- FAG 2209-K-TVH-C3 measures 45 mm across the bore and 85 mm across the outside diameter; its width is 23 mm (45 x 85 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2209.
- What does the suffix K mean in a self-aligning ball bearing?
- K indicates a tapered bore. The bearing mounts on a tapered shaft or with an adapter sleeve, which makes it easier to adjust internal radial clearance during installation.
- What is the purpose of C3 clearance in these bearings?
- C3 means greater internal radial clearance than normal. It is recommended when interference fits or thermal differences between shaft and housing could reduce clearance and affect operation.
- Can I replace a FAG bearing with another brand?
- Yes, if dimensions, bore type and radial clearance match. Check that the other brand's part number includes the same K and C3 designations, and contact us to confirm equivalence before requesting a quote.
