How the 22214-EK model number is decoded
22214-ek is the 1:12 tapered-bore execution of the 22200-series spherical roller bearing: the same two barrel-roller rows on a sphered outer raceway as 22214, but the inner-ring bore tapers 1 mm per 12 mm for adapter- or withdrawal-sleeve mounting, as listed by SKF in SKF catalogue PUB BU/P1 17000. The code breaks down as type digit 2 (double-row spherical roller), dimension series 22 (dimension series 22 (medium OD, wide)), and bore code 14 = 70 mm; dimensions 70×125×31 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. The 27.5 mm radial section height ((125−70)/2) and 2150 g catalogue mass frame a 70 mm bore bearing rated at 213 kN C — roughly 3.04 kN of dynamic capacity per millimetre of bore before application factors. For shafts with a locating shoulder, use an AH withdrawal sleeve instead of an adapter sleeve: the bearing presses against the shoulder and the sleeve is drawn out for dismounting, making the 22214-ek removable without an induction heater.
Typical equipment & failure modes
Common applications
- rolling-mill pinion and back-up shafts
- large vibrating screens and feeders
- 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
- 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 70 mm bore 22214-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 70 mm bore (125×31 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.
- The adapter sleeve is selected by actual shaft diameter, not by the 70 mm nominal bearing bore: H-sleeve part numbers span a small diameter range, so two different shaft diameters can use the same 22214-ek with different sleeves.
- Never apply the drive-up or clearance-reduction figures for this 1:12 tapered 22214-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.
- The 2150 g mass and 31 mm width mean abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the outer ring and concentrates load on one roller row of 22214-ek.
- The 213/228 kN ratings are SKF catalogue values for this tapered-bore execution (SKF 22214 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 22214-ek?
The SKF 22214 EK is a double-row spherical roller bearing with a 1:12 tapered bore, 70 mm nominal bore, 125 mm outer diameter and 31 mm width (2.756 × 4.921 × 1.22 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: C 213 kN, C0 228 kN, Pu 25.5 kN, reference speed 5,000 r/min, limiting speed 6,700 r/min, mass about 2150 g. It is mounted on an adapter (H) or withdrawal (AH) sleeve, not directly on the shaft.
What does the K suffix mean on 22214-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 22214-ek?
The sleeve is selected by the actual shaft diameter in millimetres, not only by the 70 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 22214-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 22214-ek and 22214?
They share the ISO 15 envelope and the same 213/228 kN ratings, but 22214-ek has the 1:12 tapered bore for sleeve mounting on a plain shaft, while 22214 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.
