How the 32209 model number is decoded
FAG 32209 (32209-XL) is the heavy section tapered roller choice for a 45 mm shaft — one row of tapered rollers on an asymmetric raceway inside the 85×24.75 mm ISO 355 envelope.Digit by digit, 32209 reads as bearing type 3 (single-row tapered roller), heavy section series 2, and bore reference 09 resolving to 45 mm; 85 mm OD and 24.75 mm width are the matching ISO 355 boundary values. In Schaeffler notation 32209-XL is the basic X-life execution; B-suffix variants have a steeper contact angle and are not interchangeable with the base bearing. The 20.0 mm radial section height ((85−45)/2) and 590 g catalogue mass frame a 45 mm bore bearing rated at 97 kN C — roughly 2.16 kN of dynamic capacity per millimetre of bore before application factors. A single 32209 locates the shaft in one axial direction only; mount it against a second bearing in O (back-to-back) or X (face-to-face) arrangement, and set the running clearance by the mounting procedure — not by feel.
Typical equipment & failure modes
Common applications
- differential and pinion drives
- pump and compressor shafts
- machine-tool spindles
- belt-driven fan and blower shafts
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
- preload loss as the mounted pair relaxes, letting rollers skid and smear the raceways
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- brinelling from pressing the cone or cup home through the rollers
Selection pitfalls — read before you substitute
- On this 45 mm bore, interference and temperature rise consume clearance inside a preloaded pair; calculate the residual clearance after mounting and at operating temperature — an over-tight 32209 pair heats, loses setting control and smears the roller-rib contact.
- The 322 series at 45 mm bore (85×24.75 mm) is a wider, higher-capacity section than 30209; do not substitute without re-checking shaft shoulder diameters and pair setting.
- When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 32209 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
- The tapered contact angle creates an induced axial load under pure radial force; include it in the 32209 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
- 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 97/100 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 32209 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 32209?
The 32209-XL is a single-row tapered roller bearing with 45 mm bore, 85 mm outer diameter and 24.75 mm width (1.772 × 3.346 × 0.974 in) per ISO 355. From Schaeffler HR1 (2022 edition): basic dynamic load rating C 97 kN, C0 100 kN, fatigue load limit Pu 16.1 kN, reference speed 4,850 r/min, limiting speed 10,300 r/min, mass about 590 g. It is an open, separable bearing with a pressed-steel cage.
How does the 32209 bore code work?
The last two digits of 32209 are bore code 09, so 09 × 5 = 45 mm bore. The 85 mm OD and 24.75 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.
What do the 32209 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 32209 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 32209 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 32209 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
