Decoding FAG 61809-Y
- 618Series
- Deep groove ball bearings, 618 series. Series differ in outside diameter and width even when the bore is the same.
- 09Bore
- Bore 45 mm (09 × 5).
- YSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
61809 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 61809-Y measures 45 mm across the bore and 58 mm across the outside diameter; its width is 7 mm (45 x 58 x 7 mm).

The -Y version of FAG's deep groove ball bearing line is a single-row design that accommodates radial and axial forces in both directions. Its distinguishing feature is a groove machined into the outer ring, which lets you lock the bearing axially inside the housing using a circlip instead of covers or shoulders. This simplifies housing design in gearboxes, pumps and machine tools.
Reading the part number is straightforward. The numeric portion, which spans 61809 through 61816 in this family, identifies the light 618 dimensional series. The -Y after the hyphen signals the outer-ring groove. Because the 618 series is lighter in section than the 619 or 60 series, always confirm the bore and width before substituting one bearing for another with a similar designation.
Typical installations include cast iron or sheet metal housings without locating shoulders: gearboxes, centrifugal pumps, fans, conveyors and machine tools. The groove allows mounting with a circlip, which reduces machining steps and keeps the housing compact. These bearings are commonly requested for maintaining imported equipment and for production line replacements.
When selecting, begin with the shaft and housing diameters, then specify internal clearance and sealing. The -Y series does not include integral seals; sealing depends on the equipment design or external oil seals. At assembly, check that the outer ring groove lines up with the retaining ring and that the housing depth is correct. Proper lubrication and shaft-to-housing alignment are essential, particularly where vibration is present.
Deep groove ball bearings are dimensionally interchangeable across manufacturers by series number and suffix, but internal suffixes differ and may not match. Before swapping brands, compare the groove, clearance and cage type. Send the complete part number and we will verify it for you.

Frequently asked questions
- FAG 61809-Y bearing: what are its dimensions?
- FAG 61809-Y measures 45 mm across the bore and 58 mm across the outside diameter; its width is 7 mm (45 x 58 x 7 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 61809.
- What does the -Y suffix indicate on an FAG bearing?
- It denotes a retaining ring groove on the outer ring. This groove allows the bearing to be fixed axially in the housing with a circlip, eliminating the need for covers or machined shoulders.
- How do I request a quote for a 61809-Y bearing?
- Send the complete part number and quantity via WhatsApp, and include a photo of the bearing or housing if possible. We will confirm the designation and provide a quote promptly.
- Can I use a bearing from another brand in place of this series?
- Yes, provided the dimensions and groove type match. Since internal suffixes vary between manufacturers, compare clearance, cage and sealing before installation. Send us the part number and we will check it.
