How the 32214 model number is decoded
32214-XL belongs to the FAG 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 FAG nameplate, 32214 follows the ISO 355 convention: 3 for the tapered-roller type, 2 for the heavy section, final digits 14 for the 70 mm bore. In Schaeffler notation 32214-XL is the basic X-life execution; B-suffix variants have a steeper contact angle and are not interchangeable with the base bearing. Selection arithmetic: the C0/C ratio is about 1.11 (static 216 kN against dynamic 194 kN), typical of a tapered roller sized for axial capacity, and the 34.5 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.
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 194 kN rating of 32214, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 6,200 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 194/216 kN ratings are Schaeffler HR1 values for the X-life execution; the -XL suffix denotes the premium grade and is part of the order designation, so quote it in full when purchasing.
- Schaeffler lists 32214 in the X-life basic execution; variant executions with -B or other suffixes are separate order numbers and are not interchangeable with the basic X-life bearing.
Frequently asked questions
What are the dimensions and catalogue data of 32214?
The 32214-XL 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 Schaeffler HR1 (2022 edition): basic dynamic load rating C 194 kN, C0 216 kN, fatigue load limit Pu 34.5 kN, reference speed 3,450 r/min, limiting speed 6,200 r/min, mass about 1650 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 X-life execution designations mean?
The leading 3 marks a single-row tapered roller bearing; the second digit 2 is the ISO 355 series (heavy section). The FAG -XL suffix denotes X-life premium grade; the ISO 355 series code is interchangeable with other brands. 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.
