FAG22309E1C3Double Row Spherical Roller Bearing 45 x 100 x 36 mm, Straight Bore, Reinforced Design, C3 Clearance

Product Description

What this part is

A FAG 22309-E1-C3 double-row spherical roller bearing: 45 mm straight bore, 100 mm outside diameter, 36 mm wide, reinforced E1 internal design with C3 internal clearance and a pressed steel cage.

Decoding the designation

22309: double-row spherical roller, dimension series 23, the wide tall cross-section spherical family, bore code 09 for 45 mm. E1: FAG reinforced internal design, larger roller complement and higher capacity than the base 22309. C3: radial internal clearance greater than normal. Bore Type: straight cylindrical, mounting directly on the shaft seat. Cage Type: pressed steel; FAG’s machined brass cage code in this family is E1A.

What these specifications mean in practice

A double-row spherical roller self-aligns on its spherical outer raceway, so it absorbs shaft deflection and housing misalignment that would edge-load a cylindrical roller, and it takes thrust in both directions. The 223 series is the wide section: 36 mm of width over a 45 mm bore packs in a long roller and a steep contact angle, which gives high radial capacity and the highest thrust capacity of the spherical families in a short bore length, in a larger housing envelope than a 222 or a 213 of the same bore. C3 clearance leaves running room for thermal growth and for the interference of a press fit on the shaft. The pressed steel cage keeps mass and cost down at the standard temperature and speed limits.

Quantity and configuration

Unit Quantity: 1 Pc. One complete bearing: outer ring, two spherical roller rows with the pressed steel cage, straight-bore inner ring.

Interchange guidance

The ISO base number 22309 identifies the same envelope across brands: SKF 22309 E/C3, NSK 22309EAE4C3, NTN 22309EAD1C3 and Timken 22309EJC3 are the same 45 x 100 x 36 mm size at the same clearance. FAG 22309-E1-XL-C3 is the same bearing in current FAG nomenclature. The 22309-E1-K-C3 is the tapered-bore form mounted on an adapter sleeve, and the 22309-E1-C3-W33 adds the outer-ring groove and holes. The 22209 and 21309 share the 45 mm bore in narrower sections with their own outside diameters and widths.
