How the 22213-EK model number is decoded
In SKF catalogue PUB BU/P1 17000, 22213-ek denotes the tapered-bore version (K suffix, taper 1:12) of the 22200-series spherical roller bearing: dimensioned 65×120×31 mm, it seats on an adapter or withdrawal sleeve rather than directly on a machined journal. Digit by digit, 22213-ek reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 22, and bore reference 13 resolving to 65 mm; 120 mm OD and 31 mm width are the matching ISO 15 boundary values. Reading the suffix on 22213-ek, the K (or EK/CCK) element changes only the bore — 1:12 taper for sleeve mounting — while the rest of the suffix chain (CC cages with W33 groove) keeps the same internal design, cage and W33 relubrication features as the cylindrical-bore 22213. With C 198 kN and C0 216 kN, the 22213-ek load check covers radial plus moderate axial in either direction — but below the minimum load the rollers skid, so verify P ≥ 0.01·C0 at the lightest operating point. At 65 mm bore, dismount after service is by KM locknut reversal or a hydraulic nut on larger sizes; oil-injection grooves on the bigger sleeves let pressurised oil float the 22213-ek off the taper without scoring either surface.
Typical equipment & failure modes
Common applications
- large vibrating screens and feeders
- marine propulsion and thruster shafts
- heavy crusher and screen shafts mounted and dismounted with hydraulic nuts
- long through-shafts in conveyors, where a sleeve seat avoids a precision journal
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
- brinelling from static overload or impact during handling and mounting
Selection pitfalls — read before you substitute
- Mount the 65 mm bore 22213-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 65 mm bore (120×31 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.
- A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 31 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
- A loose sleeve after the first weeks of service usually means inadequate initial drive-up; re-checking clearance without dismounting is possible through the 31 mm-wide roller rows with feeler gauges — do not simply tighten the KM nut until vibration stops.
- Shaft and housing fillets must clear the bearing chamfer so the 31 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 198/216 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 22213 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 22213-ek?
The SKF 22213 EK is a double-row spherical roller bearing with a 1:12 tapered bore, 65 mm nominal bore, 120 mm outer diameter and 31 mm width (2.559 × 4.724 × 1.22 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 198 kN, C0 216 kN, Pu 24 kN, reference speed 5,000 r/min, limiting speed 7,000 r/min, mass about 1950 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 22213-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 22213-ek?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 65 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 22213-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 22213-ek and 22213?
They share the ISO 15 envelope and the same 198/216 kN ratings, but 22213-ek has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 22213 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.
