How the 32007 model number is decoded
Ordering number 32007-X-XL in Schaeffler HR1 (2022 edition) denotes a single-row tapered roller bearing for a 35 mm shaft, low-friction section, with an open pressed-steel-cage execution and one-direction axial capacity.Digit by digit, 32007 reads as bearing type 3 (single-row tapered roller), low-friction section series 2, and bore reference 07 resolving to 35 mm; 62 mm OD and 18 mm width are the matching ISO 355 boundary values. In Schaeffler notation 32007-X-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 1.06 (static 57 kN against dynamic 54 kN), typical of a tapered roller sized for axial capacity, and the 9 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. Mounting practice for 32007: the rotating cone takes the interference fit (k5 on a 35 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
- automotive and light-truck wheel hubs
- industrial gearbox shafts and reducers
- differential and pinion drives
- pump and compressor 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
- 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
- fretting corrosion on a loose rotating shaft seat
Selection pitfalls — read before you substitute
- On this 35 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 32007 pair heats, loses setting control and smears the roller-rib contact.
- The 320 series at 35 mm bore (62×18 mm) is the low-friction, higher-speed section; it carries less thrust than a 30207 of the same bore, so verify the axial load share before swapping.
- Setting is a design value, not an assembly feel: excessive preload in the 32007 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 54 kN rating of 32007, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 14,000 r/min speed end and heavier preload only where moment stiffness dominates.
- Never press both rings through the wrong element during fitting: force for an interference shaft seat goes through the cone only, or brinell marks on the 62 mm cup race release as noise within the first running hours.
- The 54/57 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 32007 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 32007?
The 32007-X-XL is a single-row tapered roller bearing with 35 mm bore, 62 mm outer diameter and 18 mm width (1.378 × 2.441 × 0.709 in) per ISO 355. From Schaeffler HR1 (2022 edition): basic dynamic load rating C 54 kN, C0 57 kN, fatigue load limit Pu 9 kN, reference speed 7,000 r/min, limiting speed 14,000 r/min, mass about 228 g. It is an open, separable bearing with a pressed-steel cage.
How does the 32007 bore code work?
The last two digits of 32007 are bore code 07, so 07 × 5 = 35 mm bore. The 62 mm OD and 18 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.
What do the 32007 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 (low-friction 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 32007 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 32007 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 32007 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
