How the AXK150190 model number is decoded
AXK 150190 gives thrust capacity in the height of a shim: 150 mm inner track, 190 mm outer track, only 5 mm thick, with needles held by the stamped steel cage for one-direction axial load. SKF prints the AXK sizes as adjacent figures, so 150/190 reads 150 then 190 mm; the assembly has no washers of its own — order AS/LS washers or harden the mating faces. The thin section tolerates no misalignment: keep the mating faces parallel, and use the AXW spigot-flanged execution where a one-piece, housing-centred cage-plus-washer unit simplifies assembly. Selection arithmetic: C 120 kN against C0 950 kN gives a C0/C ratio of 7.92 — thrust bearings are chosen on static rating and F_a/C0 more often than on L10 life. Grease both faces before assembly so the needles stay in their pockets, especially for the 5 mm thin set; after fitting, rotate slowly and confirm the cage does not catch on the shoulder edges.
Typical equipment & failure modes
Common applications
- automotive manual and automatic transmission thrust positions
- torque converter and clutch release assemblies in passenger cars
- small gearbox gears that need a 2 mm thrust shim between a shaft and face
- light turntables, index plates and office-machine pivots
Known failure patterns
- instant raceway scoring when the assembly runs against a face below 58 HRC or with a rough finish
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
- grease churning and overheating when a high-speed thrust position is over-packed
- condensation pitting in machines that run intermittently in humid environments
- edge loading across the needle crowns when the mating faces are not square to the shaft
Selection pitfalls — read before you substitute
- Above 110 mm the large AXK sets (150–190 mm) are assembled standing up in vertical gearboxes — retain the cage or it walks off its track before the first bolt is torqued.
- The 120 kN rating is real only at 58–64 HRC face hardness; visual inspection cannot tell a 45 HRC washer from a 60 HRC one — order certified washers.
- Do not expect misalignment tolerance: a 5 mm rigid needle set edge-loads if the faces tilt even a fraction of a degree — use a spherical or AXW solution where the seat cannot be kept parallel.
- The AXK code supplies no washers: AXK 150190 arrives as the needle cage only, and a "bearing failure" on hard-faced tracks is usually a missing-AS-washer failure at ordering time.
- Match washers by the exact 150–190 mm track — a washer sized to the shaft alone leaves the needles overrunning its edge, which shears the cage.
- The 120/950 kN ratings and 232 g mass are SKF catalogue values transcribed from ch. 12.1 of PUB BU/P1 17000 (PDF table page 910); mounting data — Ea/Eb raceway diameters and the minimum load factor A — appears in the running text because the structured record carries the boundary envelope only.
Frequently asked questions
Which dimensions does the AXK 150190 have?
A AXK 150190 measures 150 mm bore × 190 mm outside diameter × 5 mm width (5.906 × 7.48 × 0.197 in). From SKF catalogue PUB BU/P1 17000: dynamic C 120 kN, static C0 950 kN, fatigue limit Pu 102 kN, reference speed 1,000 r/min, limiting speed 2,000 r/min, mass about 232 g. The contact band runs Ea 156–Eb 187 mm; hardened washers or 58–64 HRC faces are required.
What does AXK 150/190 mean?
A needle roller and cage thrust assembly (ISO 3031) for a 150 mm inner track and 190 mm outer track, 5 mm thick; one-direction axial load, washers ordered separately.
What is the difference between AXK and AXW?
AXW pairs the AXK needle set with a washer carrying an integral centring spigot that locates in a housing register, keeping cage and washer concentric as one part; AXK is the bare cage-and-needle set needing two separate washers. The AXW still needs a separate LS/AS washer or hardened face on the opposite side.
Does the AXK 150190 tolerate misalignment?
No — the 5 mm rigid needle set edge-loads on tilted faces. Keep the shaft and housing faces parallel, or choose the self-aligning roller thrust families.
