How the 22219-EK model number is decoded
In SKF catalogue PUB BU/P1 17000, 22219-ek denotes the tapered-bore version (K suffix, taper 1:12) of the 22200-series spherical roller bearing: dimensioned 95×170×43 mm, it seats on an adapter or withdrawal sleeve rather than directly on a machined journal. The code breaks down as type digit 2 (double-row spherical roller), dimension series 22 (dimension series 22 (medium OD, wide)), and bore code 19 = 95 mm; dimensions 95×170×43 mm therefore match the ISO 15 envelope. Note that K means 1:12 taper; the rarer K30 suffix means 1:30. Adapter sleeves (H) and withdrawal sleeves (AH) are ordered separately by shaft diameter, and the KM locknut plus MB lock washer used for drive-up are also separate components. At 3,600 r/min reference speed the 37.5 mm-section 22219-ek is governed thermally by lubricant flow through the W33 groove and the two-row roller complement; grease or oil selection should be made against that value, with 4,800 r/min as the mechanical ceiling. Mounting on the 1:12 taper is controlled by clearance reduction or measured axial drive-up, never by locknut torque: SKF tables give the target radial-clearance decrease for the 95 mm 22219-ek, checked with feeler gauges before and after drive-up.
Typical equipment & failure modes
Common applications
- heavy conveyor head shafts in mining
- jaw and cone crusher main shafts
- stepped shafts fitted with withdrawal sleeves against a fixed shoulder
- fan and pulley shafts that need periodic bearing removal in the field
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- sleeve seizure and shaft seat damage from omitting the anti-seize film between withdrawal sleeve and journal before drive-up
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- seal-lip wear and grease purge loss when an open bearing is run without functioning housing seals
Selection pitfalls — read before you substitute
- Mount the 95 mm bore 22219-ek by induction heating (max 120 °C) or oil injection — driving a bearing of this section home through the rollers brinells both raceways, and the damage only speaks up as vibration hours later.
- The 22200-series series at 95 mm bore (170×43 mm) is the general-purpose spherical roller envelope; stepping up to 223 adds capacity and width, stepping to 230 trims the OD — neither is interchangeable without re-checking shoulders and speed.
- Never apply the drive-up or clearance-reduction figures for this 1:12 tapered 22219-ek to a bearing of the other taper (1:12 vs 1:30); the steeper taper moves far less clearance per nut turn and the targets come from different catalogue tables.
- Never apply the drive-up or clearance-reduction figures for this 1:12 tapered 22219-ek to a bearing of the other taper (1:12 vs 1:30); the steeper taper moves far less clearance per nut turn and the targets come from different catalogue tables.
- Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 22219-ek; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 393/450 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 22219 EK); sleeve, KM nut and MB washer are separate order numbers, and the catalogue version (SKF catalogue PUB BU/P1 17000) should travel with the mounting specification.
Frequently asked questions
What are the dimensions and catalogue data of 22219-ek?
The SKF 22219 EK is a double-row spherical roller bearing with a 1:12 tapered bore, 95 mm nominal bore, 170 mm outer diameter and 43 mm width (3.74 × 6.693 × 1.693 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 393 kN, C0 450 kN, Pu 45.5 kN, reference speed 3,600 r/min, limiting speed 4,800 r/min, mass about 5450 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 22219-ek?
K marks a 1:12 tapered bore for sleeve mounting — SKF writes EK or CCK(/W33), FAG writes -K- inside the suffix chain for sleeve mounting. The bearing seats on an H-series adapter sleeve with a KM locknut and MB lock washer (plain shaft, h9 tolerance), or on an AH withdrawal sleeve against a shaft shoulder. The rarer K30 suffix would instead mean a 1:30 taper; dimension series 40/41 spherical rollers commonly use it.
Which adapter sleeve fits the 22219-ek?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 95 mm nominal bore: SKF H-sleeve numbers each cover a small shaft-diameter range and are width-series specific (H39/H30/H31/H32 matching dimension series 39/40/31/32), and each kit bundles the sleeve, KM locknut and MB lock washer. For shoulder locations use an AH withdrawal sleeve instead. Confirm the sleeve number against the SKF catalogue PUB BU/P1 17000 mounting tables for your shaft size.
How is the 22219-ek driven up and checked?
Mounting is controlled by radial-clearance reduction or axial drive-up distance from the SKF catalogue tables for the 1:12 taper, never by locknut torque. Measure clearance with feeler gauges before and after tightening the KM nut, stop at the tabulated decrease, and lock the MB washer tab. Over-drive removes too much clearance (inner-ring cracking risk); under-drive lets the sleeve creep and fret.
What is the difference between 22219-ek and 22219?
They share the ISO 15 envelope and the same 393/450 kN ratings, but 22219-ek has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 22219 has a cylindrical bore for direct mounting on a machined interference journal (typically k5 with H7 housing). They are separate order numbers, not interchangeable in the same shaft arrangement.
