How the 32214-SKF model number is decoded
SKF 32214 belongs to the SKF single-row tapered roller range — the 70 mm bore entry in the 32200 series, dimensioned 125 mm OD and 33.25 mm wide to the ISO 355 boundary plan.On the SKF nameplate, 32214 follows the ISO 355 convention: 3 for the tapered-roller type, 22 for the heavy section, final digits 14 for the 70 mm bore. In SKF suffix language a bare 32214 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. Selection arithmetic: the C0/C ratio is about 1.07 (static 208 kN against dynamic 195 kN), typical of a tapered roller sized for axial capacity, and the 24.5 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. Note the minimum-axial-load requirement: at light radial load and high speed the rollers of 32214 must still be held into the rib contact, which is another reason the catalogue recommends paired mounting with controlled setting. Load system: the 195 kN basic dynamic rating C and 208 kN static rating C0 give a C0/C balance of 1.07, and dividing C by the 70 mm bore yields 2.79 kN per millimetre of journal — a density metric that compares across families; the 24.5 kN fatigue limit Pu is the floor beneath which the adjusted-life calculation drops below acceptable L10 hours for a 70 mm shaft carrying variable duty.
Typical equipment & failure modes
Common applications
- heavy industrial gearboxes and speed reducers
- large process pump and compressor shafts
- rolling-mill auxiliary drives
- crane sheave and hoist gearboxes
Known failure patterns
- cup or cone misalignment when the separable rings are not seated square during mounting
- loose cup rotation in the housing when the specified press fit is not achieved
- false brinelling on idle paired sets exposed to machine vibration
- roller large-end smearing against the cone rib after EP lubricant film failure
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- grease degradation after long shelf storage without rotation or re-greasing
Selection pitfalls — read before you substitute
- Mount the 70 mm bore 32214 by induction heating of the cone (max 120 °C — the pressed-steel cage sets the ceiling, not the steel); driving it home through the cup or rollers brinells the tapered raceway.
- The 322 series at 70 mm bore (125×33.25 mm) is a wider, higher-capacity section than 30214; do not substitute without re-checking shaft shoulder diameters and pair setting.
- Setting is a design value, not an assembly feel: excessive preload in the 32214 pair raises operating temperature and can trigger thermal runaway, while too little lets the rollers skid and smear the raceway under light load.
- At the 195 kN rating of 32214, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 5,300 r/min speed end and heavier preload only where moment stiffness dominates.
- The pressed-steel cage is rated for standard industrial service; sustained running above the limiting speed or with degraded lubricant wears the cage pockets — inspect the cage at every relubrication interval.
- The 195/208 kN ratings are SKF catalogue 17000 values for the basic execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification and re-verify for critical drives.
- SKF lists several executions of 32214 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32214 designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What are the dimensions and catalogue data of 32214?
The SKF 32214 is a single-row tapered roller bearing with 70 mm bore, 125 mm outer diameter and 33.25 mm width (2.756 × 4.921 × 1.309 in) per ISO 355. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 195 kN, C0 208 kN, fatigue load limit Pu 24.5 kN, reference speed 4,300 r/min, limiting speed 5,300 r/min, mass about 1600 g. It is an open, separable bearing with a pressed-steel cage.
How does the 32214 bore code work?
The last two digits of 32214 are bore code 14, so 14 × 5 = 70 mm bore. The 125 mm OD and 33.25 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.
What do the 32214 series and basic execution designations mean?
The leading 3 marks a single-row tapered roller bearing; the second digit 22 is the ISO 355 series (heavy section). The SKF catalogue lists the ISO 355 dimension-series code after the bare number. A steeper-contact-angle variant (B suffix) is a different order number and is not interchangeable with the basic execution.
Can a single 32214 take axial load in both directions?
No — one single-row tapered roller bearing reacts thrust in one direction only, and under radial load its contact angle induces an axial force. Use two bearings as a matched pair: O (back-to-back) for a rigid, moment-resisting arrangement, X (face-to-face) where thermal expansion must be tolerated, or tandem where one-direction thrust is shared.
How does 32214 compare with a ball bearing of the same bore?
A tapered roller bearing has line contact and a steep contact angle: much higher combined axial-plus-radial capacity and shock resistance than a ball bearing of the same bore, at the cost of speed, one-direction thrust, mandatory pairing for reversing loads and a minimum axial load requirement. A ball bearing cannot be dropped into a combined-load 32214 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
