Decoding the designation

22219 — FAG’s number for the ISO 219 spherical roller size, 95 x 170 x 43 mm.

E1 — reinforced internal execution with a higher roller complement.

XL — X-life execution, with the raceway geometry and surface quality that carry the uprated ratings.

K — 1:12 tapered bore, mounts on an H319 adapter sleeve.

C4 — radial internal clearance greater than C3.

What these specs mean in practice

Dynamic Load Rating: 380 kN. Static Load Rating: 415 kN. On a double-row spherical roller bearing the static figure standing above the dynamic figure is the published relationship: two rows of barrel rollers on a common sphered outer raceway present an enormous stationary contact area. The sphered outer raceway lets the inner ring and roller set swivel inside the outer ring, so the bearing absorbs shaft deflection and housing misalignment without edge loading, and it takes thrust in both directions as well as radial load. Internal Clearance: C4, above C3, which is what a tapered-bore mounting wants: driving the inner ring up the sleeve taper expands it and consumes clearance, so the assembly starts with more than normal so it finishes with the right amount. Limiting Speed: 4,850 rpm. Mass: 4.07 kg.

Mounting data

Bore: 95 mm, 1:12 taper. Outside Diameter: 170 mm. Overall Width: 43 mm. The 95 mm tapered bore seats on an H319 adapter sleeve, whose tapered outside diameter is 95 mm over an 85 mm cylindrical shaft seat, secured with a KM 19 locknut and an MB 19 lockwasher. Radial internal clearance is set by measured drive-up on the taper rather than by the shaft tolerance.

Quantity and configuration

Unit Quantity: 1 Pc. Supplied as a single bearing.

Interchange guidance

Manufacturer part number variants: 22219-E1-XL-K-C4, 22219-E-XL-K-C4, 22219EXLKC4, 22219E1XLKC4, 22219EK. The 22219 K envelope is an ISO-standard spherical roller size, so an SKF 22219 EK, NSK 22219 EAKE4 and Timken 22219KEJW33 share the 95 x 170 x 43 mm boundary dimensions and the 1:12 taper. A straight-bore 22219-E1-XL is the same bearing on a cylindrical seat and is a related size rather than an interchange; a W33 execution adds an outer-ring lubrication groove with three radial feed holes.
