How the AXK1024 model number is decoded
SKF's AXK 1024 is not a complete bearing — the stamped steel cage spaces the thrust needles, while hardened AS/LS raceway washers (or shaft and housing faces at 58–64 HRC) provide the two raceways. SKF prints the AXK sizes as adjacent figures, so 10/24 reads 10 then 24 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. Speed planning separates the 5,300 r/min thermal reference from the 10,000 r/min mechanical limiting speed. Thrust bearings govern the thermal speed of many vertical arrangements, and oil circulation raises the usable speed substantially above grease values. Grease both faces before assembly so the needles stay in their pockets, especially for the tiny 2 mm thin set; after fitting, rotate slowly and confirm the cage does not catch on the shoulder edges.
Typical equipment & failure modes
Common applications
- 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
- two-wheeler gearbox selector and layshaft thrust faces
Known failure patterns
- needle-row denting from a single hard particle trapped in the 2 mm section
- 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
- false brinelling and rust-red witness marks on standby machines under external vibration
- instant raceway scoring when the assembly runs against a face below 58 HRC or with a rough finish
Selection pitfalls — read before you substitute
- The AXK 1024 is watchmaking-scale (2 mm thick, 3 g): handle it with tweezers, grease it onto its washer, and assume one dropped or cocked assembly is one ruined bearing.
- Match washers by the exact 10–24 mm track — a washer sized to the shaft alone leaves the needles overrunning its edge, which shears the cage.
- the 5,300 r/min reference speed is the thermal criterion under load, the 10,000 r/min limiting speed assumes hardened, ground, oiled faces; soft or dry faces drop the real ceiling drastically.
- The 8.5 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 2 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 8.5/26 kN ratings and 3 g mass are SKF catalogue values transcribed from ch. 12.1 of PUB BU/P1 17000 (PDF table page 908); 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
Why does an AXK assembly fail early?
Almost always the track: missing/undersized washers, hardness below 58 HRC, a sharp shoulder edge catching the cage, or contamination in the thin section. Rating 8.5 kN assumes all of these are correct.
Which dimensions does the AXK 1024 have?
A AXK 1024 measures 10 mm bore × 24 mm outside diameter × 2 mm width (0.394 × 0.945 × 0.079 in). From SKF catalogue PUB BU/P1 17000: dynamic C 8.5 kN, static C0 26 kN, fatigue limit Pu 3 kN, reference speed 5,300 r/min, limiting speed 10,000 r/min, mass about 3 g. The contact band runs Ea 12–Eb 23 mm; hardened washers or 58–64 HRC faces are required.
What does AXK 10/24 mean?
A needle roller and cage thrust assembly (ISO 3031) for a 10 mm inner track and 24 mm outer track, 2 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.
