How the 32222 model number is decoded
For a 110 mm shaft carrying combined load, FAG lists 32222 under catalogue execution 32222-XL: one open single-row tapered roller bearing in the heavy section of the 32200 family.On the FAG nameplate, 32222 follows the ISO 355 convention: 3 for the tapered-roller type, 2 for the heavy section, final digits 22 for the 110 mm bore. In Schaeffler notation 32222-XL is the basic X-life execution; B-suffix variants have a steeper contact angle and are not interchangeable with the base bearing. Catalogue mass 7200 g for the 110×200×56 mm open execution covers the pressed-steel cage and standard roller complement; sealed or special-clearance variants differ slightly in mass and carry their own order numbers. Mounting practice for 32222: the rotating cone takes the interference fit (m6 on a 110 mm shaft), the cup slides for axial location, and reversing-thrust duty demands a paired O/X set rather than one bearing.
Typical equipment & failure modes
Common applications
- paper-machine and printing rolls
- construction machinery drives
- marine deck machinery shafts
- heavy industrial gearboxes and speed reducers
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
- thermal preload runaway in an O-arrangement pair when inner-ring heat expands the setting
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Mount the 110 mm bore 32222 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 110 mm bore (200×56 mm) is a wider, higher-capacity section than 30222; 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 32222 pair raises operating temperature and can trigger thermal runaway, while too little lets the rollers skid and smear the raceway under light load.
- A single 32222 cannot locate the shaft axially in both directions; mounting it singly on a reversing-thrust shaft leaves one direction uncontrolled — always use an O or X matched pair for bidirectional location.
- Shaft and housing fillets must clear the bearing chamfer so the 56 mm-wide cup seats square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 490/590 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 32222 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 32222?
The 32222-XL is a single-row tapered roller bearing with 110 mm bore, 200 mm outer diameter and 56 mm width (4.331 × 7.874 × 2.205 in) per ISO 355. From Schaeffler HR1 (2022 edition): basic dynamic load rating C 490 kN, C0 590 kN, fatigue load limit Pu 88 kN, reference speed 2,410 r/min, limiting speed 4,150 r/min, mass about 7200 g. It is an open, separable bearing with a pressed-steel cage.
How does the 32222 bore code work?
The last two digits of 32222 are bore code 22, so 22 × 5 = 110 mm bore. The 200 mm OD and 56 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.
What do the 32222 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 32222 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 32222 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 32222 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
