How the 32007-SKF model number is decoded
Ordering number SKF 32007 X in SKF catalogue PUB BU/P1 17000 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 20, and bore reference 07 resolving to 35 mm; 62 mm OD and 18 mm width are the matching ISO 355 boundary values. In SKF suffix language a bare 32007 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 1.03 (static 54 kN against dynamic 52.3 kN), typical of a tapered roller sized for axial capacity, and the 5.85 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. Operating context for the 35 mm bore: a shaft of this diameter in the medium-bore band typically runs between 28000 and 42000 r/min in real machinery, and the 62 mm outside diameter places the housing shoulder at 70 mm outer abutment; the 18 mm width and 230 g mass together set the shaft critical speed and the housing resonance check for this 32000-series envelope.
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 52.3 kN rating of 32007, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 10,000 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 52.3/54 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 32007 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32007 X designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What are the dimensions and catalogue data of 32007?
The SKF 32007 X 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 SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 52.3 kN, C0 54 kN, fatigue load limit Pu 5.85 kN, reference speed 8,500 r/min, limiting speed 10,000 r/min, mass about 230 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 basic execution designations mean?
The leading 3 marks a single-row tapered roller bearing; the second digit 20 is the ISO 355 series (low-friction 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 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.
