FAG22220ESK.TVPBSpherical Roller Bearing 100x180x46 mm Double Row 1:12 Tapered Bore Lubrication Groove and Holes Polyamide Cage

Product Description

What this part is:

A double-row spherical roller bearing, 100 mm bore × 180 mm outside diameter × 46 mm width, main dimensions to DIN 635-2, with a tapered bore of 1:12 taper. Two rows of symmetrical barrel rollers run in one concave spherical raceway in the outer ring, so the inner ring and roller set swivel within the outer ring. The result is a self-aligning bearing with very high radial capacity that also takes thrust in both axial directions.

Decoding the designation:

• 222 — spherical roller bearing, 222 dimension series: 46 mm width across a 40 mm radial section at this bore.
• 20 — bore code for a 100 mm bore.
• E — reinforced internal design, with larger rollers and a higher roller count than the base design in the same envelope.
• S — annular lubrication groove in the outer ring outside diameter with three radial lubrication holes, the feature other schemes label W33.
• K — tapered bore, taper 1:12.
• TVPB — one-piece window cage in glass-fibre reinforced polyamide 6.6.
• No clearance suffix: normal radial internal clearance, CN.

What these specs mean in practice:

The polyamide cage is light, has low inertia and generates little friction against the rollers, which lowers running temperature and lets the bearing accelerate hard. Its temperature ceiling is the trade: a glass-fibre reinforced polyamide cage is rated for continuous service to about 120 °C, well below the 200 °C the steel rings themselves tolerate, and it is sensitive to aged oil at elevated temperature. Where the position runs hotter than that, the machined brass and pressed steel cage variants of the same bearing take over.

The lubrication groove and three holes turn the outer ring into a distribution gallery, so lubricant fed through a housing port reaches the roller path of both rows directly. The 1:12 tapered bore makes the radial clearance a mounting adjustment rather than a tolerance outcome: drive-up distance up the taper expands the inner ring and sets the residual clearance.

Bore type and mating sleeve:

Bearing only. The matching adapter sleeve is the H320, and the matching withdrawal sleeve is the AHX320.

Quantity and configuration:

One bearing, open on both faces, no seals, no shields, no snap ring.

Fitting notes:

The 1:12 bore seats either directly on a tapered shaft journal, retained by a locknut, or on an H320 adapter sleeve on a plain cylindrical shaft; the H320 bore takes a 90 mm shaft seat, one bore-code step below the bearing bore. Residual radial internal clearance is measured across the roller rows with a feeler gauge and set by drive-up distance. Both rings abut square shoulders inside the da and Da limits above. The housing lubrication port aligns with the outer ring groove, which runs the full circumference, so outer ring orientation is unconstrained.

Interchange guidance:

Equivalent designations in other schemes for the same specification: 22220 EK/W33 in the SKF scheme, 22220KEJW33 in the Timken scheme, and 22220-E1-XL-K-TVPB as the current Schaeffler catalogue form. Related sizes rather than interchanges: 22220ESK.TVPB.C3 is the same bearing at C3 clearance instead of normal; 22220-E1-XL-K with a brass or pressed steel cage shares the envelope but carries a higher temperature ceiling; 22220E without the K shares the 100 × 180 × 46 mm envelope with a straight cylindrical bore; 22320K carries the 100 mm taper bore in a heavier 215 mm outside diameter series.
