How the 32926 model number is decoded

SKF 32926 belongs to the SKF single-row tapered roller range — the 130 mm bore entry in the 32900 series, dimensioned 180 mm OD and 32 mm wide to the ISO 355 boundary plan.Digit by digit, 32926 reads as bearing type 3 (single-row tapered roller), very-light thin section series 29, and bore reference 26 resolving to 130 mm; 180 mm OD and 32 mm width are the matching ISO 355 boundary values. The SKF catalogue adds the ISO 355 dimension-series code after the bare number (e.g. 2CC); it is the dimensional series, not a separate part number. At 2,600 r/min reference speed the 25.0 mm-section 32926 is governed thermally by preload and lubricant flow; grease or oil selection should be made against that value, with 3,200 r/min as the mechanical ceiling. Specify pairs rather than single units wherever thrust reverses: the tapered contact of 32926 generates an induced axial load under radial force, and an unpaired bearing on a reversing shaft will run slack and fret its seat. Operating context for the 130 mm bore: a shaft of this diameter in the xl-bore band typically runs between 104000 and 156000 r/min in real machinery, and the 180 mm outside diameter places the housing shoulder at 188 mm outer abutment; the 32 mm width and 2400 g mass together set the shaft critical speed and the housing resonance check for this 32900-series envelope.

Typical equipment & failure modes

Common applications

  • rolling-mill roll-neck bearings
  • heavy-duty rolling-mill gearboxes
  • large crusher and mineral-processing drives
  • wind-turbine main 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
  • roller large-end smearing against the cone rib after EP lubricant film failure
  • false brinelling on idle paired sets exposed to machine vibration
  • cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
  • edge loading from shaft deflection or housing misalignment

Selection pitfalls — read before you substitute

  • At 130 mm bore the cone mass is high enough that cocking during mounting damages the cage and rib; guide the ring square, confirm seat contact around the full circumference, and re-check setting after the first thermal cycle of the paired set.
  • The 329 series at 130 mm bore (180×32 mm) is the very-light thin-section envelope: the smallest OD of any tapered family at this bore, ideal where radial space is severely limited, but capacity is well below a 30226 of the same bore — confirm the L10 life and minimum axial load before choosing it.
  • The tapered contact angle creates an induced axial load under pure radial force; include it in the 32926 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
  • The tapered contact angle creates an induced axial load under pure radial force; include it in the 32926 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
  • Shaft and housing fillets must clear the bearing chamfer so the 32 mm-wide cup seats square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
  • The 245/365 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 32926 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32926 designation when purchasing and match the execution to the mounting arrangement.

Frequently asked questions

What are the dimensions and catalogue data of 32926?

The SKF 32926 is a single-row tapered roller bearing with 130 mm bore, 180 mm outer diameter and 32 mm width (5.118 × 7.087 × 1.26 in) per ISO 355. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 245 kN, C0 365 kN, fatigue load limit Pu 38 kN, reference speed 2,600 r/min, limiting speed 3,200 r/min, mass about 2400 g. It is an open, separable bearing with a pressed-steel cage.

How does the 32926 bore code work?

The last two digits of 32926 are bore code 26, so 26 × 5 = 130 mm bore. The 180 mm OD and 32 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.

What do the 32926 series and basic execution designations mean?

The leading 3 marks a single-row tapered roller bearing; the second digit 29 is the ISO 355 series (very-light thin 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 32926 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 32926 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 32926 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
