FAG22219ESTVPBC3Spherical Roller Bearing – Straight Bore, 95 mm ID, 170 mm OD, 43 mm Width, C3 Clearance, Open

Product Description

What this part is

An FAG 22219-ES-TVPB-C3 double-row spherical roller bearing. Straight cylindrical bore 95 mm, outside diameter 170 mm, width 43 mm, open on both faces, with a lubrication groove and radial feed holes in the outer ring and a glass-fibre reinforced polyamide cage.

Decoding the designation

22219 is the ISO base number; the 222 dimension series is the wide double-row spherical roller family, and bore code 19 is 95 mm. E marks the reinforced internal design with larger rollers. S is the FAG lubrication provision — an annular groove in the outer ring with radial feed holes, the same feature ISO writes as W33. TVPB is the glass-fibre reinforced polyamide cage. C3 is greater-than-normal radial internal clearance.

What these specs mean in practice

Two rows of barrel-profile rollers run on a common spherical outer raceway, so the bearing carries very high radial load, takes thrust in both directions, and self-aligns to absorb shaft deflection and housing misalignment. C3 clearance gives room for interference-fit growth and for a hot inner ring, which suits a shaft running well above ambient. The polyamide cage is light and quiet and carries a continuous service ceiling of roughly 120 °C, below what a brass M or MB cage in the same envelope would tolerate.

Bore and mounting form

Straight cylindrical bore. It seats directly on a cylindrical shaft journal, with no taper, no adapter sleeve and no withdrawal sleeve in the mounting.

Quantity and configuration

One complete bearing — inner ring, outer ring, two roller rows and cage as a single assembly. 1 Pc.

Fitting notes

Mounting is by cold press or by even induction heating of the inner ring; the polyamide cage sets the heating limit, so ring temperature is held under the cage ceiling. The outer-ring feed holes are aligned with the housing lubrication port on assembly.

Interchange guidance

SKF 22219 EK, NSK 22219 EAE4 and Timken 22219EJW33C3 sit in the same 95 x 170 x 43 mm envelope with the same straight bore and groove-and-hole provision. Cage material and clearance are part of the specification: a brass-cage 22219 E1A-MB or a CN-clearance 22219 E is a related size rather than a like-for-like swap.
