How the AXK7095 model number is decoded
The AXK assembly AXK 7095 covers 70–95 mm in a 4 mm section and is rated 49 kN dynamic / 255 kN static: the thinnest rolling thrust support available for that seat. SKF prints the AXK sizes as adjacent figures, so 70/95 reads 70 then 95 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. No factor A is published for needle thrust sets: keep a light preload so the needles roll rather than skid — springs, shim preload or the gear's own backlash take-up are part of the selection, not an accessory. Mounting: harden and grind both mating faces to 58–64 HRC over the full Ea 74–Eb 93 mm band (or fit AS/LS washers), drop the 4 mm cage in flat, and never press or hammer the needle complement.
Typical equipment & failure modes
Common applications
- 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
- compact drives where hardened washers replace a machined raceway shoulder
Known failure patterns
- instant raceway scoring when the assembly runs against a face below 58 HRC or with a rough finish
- cage wear from rollers being dragged through unloaded zones under fluctuating thrust
- grease churning and overheating when a high-speed thrust position is over-packed
- hard-particle indentation where oil or grease filtration is inadequate
- edge loading across the needle crowns when the mating faces are not square to the shaft
Selection pitfalls — read before you substitute
- At 70 mm track diameter, face hardness decides everything: a ground-but-soft washer looks correct yet ribbons within months; specify 58–64 HRC on the drawing.
- The 49 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 4 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 1,800 r/min reference speed is the thermal criterion under load, the 3,600 r/min limiting speed assumes hardened, ground, oiled faces; soft or dry faces drop the real ceiling drastically.
- The AXK code supplies no washers: AXK 7095 arrives as the needle cage only, and a "bearing failure" on hard-faced tracks is usually a missing-AS-washer failure at ordering time.
- The 49/255 kN ratings and 60 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
What does AXK 70/95 mean?
A needle roller and cage thrust assembly (ISO 3031) for a 70 mm inner track and 95 mm outer track, 4 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 7095 tolerate misalignment?
No — the 4 mm rigid needle set edge-loads on tilted faces. Keep the shaft and housing faces parallel, or choose the self-aligning roller thrust families.
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 49 kN assumes all of these are correct.
