FAG22224ESTVPBC3Double-Row Spherical Roller Bearing 120x215x58 mm, Straight Bore, Reinforced E Design, Polyamide Cage, C3 Clearance

Product Description

What this part is

A 222-series double-row spherical roller bearing in the ISO 22224 envelope — 120 mm bore, 215 mm outside diameter, 58 mm width — in FAG’s reinforced E design with a polyamide cage and C3 internal clearance. Two rows of barrel rollers ride a single spherical outer raceway, so the inner ring and roller assembly swivel bodily inside the outer ring. That self-aligning action is why this family survives shaft deflection and out-of-line housings that would edge-load and destroy a cylindrical roller bearing in the same position.

Decoding the designation

Read strictly in FAG’s scheme. The same letters mean different things on SKF or NTN numbers, so this decode does not transfer.

22224 — ISO base number: 222 series double-row spherical roller, 120 mm bore.E / ES — FAG’s reinforced internal design: larger rollers and more of them in the same envelope, which is what lifts the load rating over the older non-E design.TVPB — glass-fibre-reinforced polyamide (nylon) cage. Light, low-friction, quiet, forgiving of momentary lubricant starvation, but temperature-limited compared with a brass MB cage and not the choice next to a hot process or under severe shock.C3 — greater-than-normal radial internal clearance.No K — straight cylindrical bore. No adapter sleeve involved.W33 is not part of this designation, so do not assume an outer-ring lubrication groove; verify against the ring before specifying a housing that feeds one.

Correcting the source data

The previous copy stated the bearing was “manufactured in the United States.” FAG is a Schaeffler brand and nothing on the part or in FAG’s published data supports a USA origin, so the claim is removed and no origin is now published. The old text also carried marketing filler and shipping and contact boilerplate, all of which has been deleted.

Why C3 clearance matters, and how it fails

Radial internal clearance is the small amount of free play between rollers and raceways before the bearing is fitted and heated. Fitting consumes it: an interference fit on the shaft expands the inner ring, and a hot inner ring expands more than the housing-cooled outer ring. C3 starts with extra clearance so that after fitting and thermal growth there is still running clearance left. Get it wrong in either direction and the bearing suffers. Too little residual clearance and the rollers are preloaded, running hot and spalling early. Too much — C3 in a cool, lightly loaded position with a loose shaft fit — and the load spreads over too few rollers, letting the rings creep, skid and generate noise. C3 is not a general upgrade; it is a match to a specific fit and temperature case.

Published ratings and mounting data

Those figures come from a distributor mirror of FAG data for the E1 designation, not from a FAG page for ES.TVPB, so treat them as provisional and indicative of the reinforced E design rather than as a verified rating for this exact suffix. The rating cells for this part are left blank rather than filled with a sibling’s numbers. Note also that a polyamide cage typically imposes a lower permissible temperature and speed than the brass-cage version of the same number.

Quantity and configuration

Stock is recorded as 2. Each bearing is a complete, non-separable unit — outer ring, both roller rows, cage, inner ring. There is no matched-pair convention in this family, so two units means two independent bearings, which conveniently suits a two-bearing shaft with one fixed and one floating position.

Fitting notes

Heat-mount or press with proper tooling; never drive the rings through the rollers. Confirm your shaft and housing tolerances were specified for a C3 bearing before fitting — swapping a normal-clearance bearing for a C3 without revisiting the fits changes the residual clearance you end up with. Keep the polyamide cage away from temperatures beyond its rating and from lubricants and additives aggressive to nylon.

Interchange guidance

Same-envelope alternates include FAG 22224-E1-C3 and 22224-E1A-M-C3, SKF 22224 in C3, NTN 22224 and NSK 22224 in C3. Clearance class must match. Cage material should match too if the position is hot or shock-loaded — a brass-cage MB bearing is the substitute to reach for in that case, not the reverse. Do not cross into the 232 series (23224): it is wider in the same bore and will not fit a 222 housing.
