How the 32026-SKF model number is decoded
For a 130 mm shaft carrying combined load, SKF lists 32026 under catalogue execution SKF 32026 X: one open single-row tapered roller bearing in the low-friction section of the 32000 family.The code breaks down as type prefix 3 (tapered roller), series 20 (the low-friction section), and bore code 26 = 130 mm; dimensions 130×200×45 mm therefore match the ISO 355 envelope. In SKF suffix language a bare 32026 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 1.39 (static 540 kN against dynamic 388 kN), typical of a tapered roller sized for axial capacity, and the 55 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. Specify pairs rather than single units wherever thrust reverses: the tapered contact of 32026 generates an induced axial load under radial force, and an unpaired bearing on a reversing shaft will run slack and fret its seat. Journal and housing interface: the 130 mm bore takes a m6 shaft seat (upper deviation ~0.260 mm for this diameter range) and the 200 mm outside diameter pairs with an H7 housing bore tolerance band of 200.000/200.020 mm; the 45 mm width defines the shoulder depth, and the 4950 g cone-plus-cup assembly is the dead load on the shaft during thermal expansion calculations.
Typical equipment & failure modes
Common applications
- heavy-duty rolling-mill gearboxes
- large crusher and mineral-processing drives
- wind-turbine main shafts
- marine propulsion gearboxes
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
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- preload loss as the mounted pair relaxes, letting rollers skid and smear the raceways
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- mounting score marks when the cone is cocked over the shaft keyway or a burr
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 320 series at 130 mm bore (200×45 mm) is the low-friction, higher-speed section; it carries less thrust than a 30226 of the same bore, so verify the axial load share before swapping.
- When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 32026 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
- When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 32026 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
- The 4950 g mass and 45 mm width mean spacer and abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the contact angle and concentrates load on one rib of 32026.
- The 388/540 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 32026 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32026 X designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What are the dimensions and catalogue data of 32026?
The SKF 32026 X is a single-row tapered roller bearing with 130 mm bore, 200 mm outer diameter and 45 mm width (5.118 × 7.874 × 1.772 in) per ISO 355. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 388 kN, C0 540 kN, fatigue load limit Pu 55 kN, reference speed 2,400 r/min, limiting speed 3,000 r/min, mass about 4950 g. It is an open, separable bearing with a pressed-steel cage.
How does the 32026 bore code work?
The last two digits of 32026 are bore code 26, so 26 × 5 = 130 mm bore. The 200 mm OD and 45 mm width come from the ISO 355 dimension-series plan, shared with other tapered bearings of the same code.
What do the 32026 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 32026 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 32026 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 32026 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
