FAG22234ESTVPW33Double-Row Spherical Roller Bearing – Straight Bore, 170 mm ID, 310 mm OD, 86 mm Width, Open, W33 Lubrication Groove, Polyamide Cage, CN Clearance

Product Description

What this part is

FAG 22234ES.TVP double-row spherical roller bearing. Series: 222. Bore: 170 mm. Outside Diameter: 310 mm. Width: 86 mm. Straight bore, open, with a lubrication groove and radial feed holes in the outer ring.

Decoding the designation

222 is the medium-width double-row spherical roller series. E marks the reinforced internal design, giving a larger roller complement and higher capacity than the base series. S is the lubrication groove with radial feed holes in the outer ring, the same feature other makers code as W33. TVP is a glass-fibre reinforced polyamide cage. The absence of a K means the bore is straight and seats directly on the shaft.

What these specs mean in practice

Dynamic Load Rating: 1,320 kN (296,748 lbf). Static Load Rating: 1,570 kN (352,955 lbf). Fatigue Load Limit: 144 kN. Limiting speed: 2,550 rpm. Reference speed: 1,780 rpm. On a double-row spherical roller the static rating sits above the dynamic rating, and both rows share load, so the bearing takes thrust in either direction as well as heavy radial load. The two roller rows run on a common spherical outer raceway, which lets the inner ring and rollers swivel to absorb shaft deflection and mounting misalignment. Axial load factors: Y1 2.54, Y2 3.87, Y0 2.6, with e 0.26.

Quantity and configuration

One bearing. Straight bore, so it mounts directly on a cylindrical shaft seat with no adapter sleeve in the assembly.

Fitting notes

Minimum shaft shoulder diameter: 187 mm. Maximum housing shoulder diameter: 293 mm. Maximum recess radius: 3 mm. Minimum chamfer dimension: 4 mm. Inner ring raceway diameter: 199.8 mm. Outer ring bore diameter: 275.4 mm. Lubrication groove width: 17.7 mm. Lubrication hole diameter: 9.5 mm, so grease or oil can be fed through the housing straight into the roller path. Internal Clearance: CN, the normal group.

Interchange guidance

Searchable variants: 22234ES.TVP, 22234-ES-TVP-W33, 22234ESTVPW33, 22234 ES TVP W33, 22234E. Schaeffler’s current designations on this envelope are 22234-E1-XL and 22234-E1A-XL-M. Same-envelope parts from other makers: SKF 22234 CC/W33, NSK 22234EAE4, Timken 22234EJW33, NTN 22234EMD1, Koyo 22234RZW33 — each carries a different cage execution, so cage material and the resulting speed rating differ between them.
