How the AXK80105 model number is decoded
AXK 80105 gives thrust capacity in the height of a shim: 80 mm inner track, 105 mm outer track, only 4 mm thick, with needles held by the stamped steel cage for one-direction axial load. In AXK 80105 the number is the boundary plan, not a bore code: 80/105, with the 4 mm assembly thickness fixed by the ISO 3031 plan and Ea/Eb 84/103 mm marking the actual needle-contact band. 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. The 63 g mass and 4 mm axial height sit between 80 and 105 mm washer diameters; check the seat shoulder spans the full ring face — a narrow shoulder causes washer fretting long before fatigue does. Mounting: harden and grind both mating faces to 58–64 HRC over the full Ea 84–Eb 103 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
- 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
- automotive manual and automatic transmission thrust positions
Known failure patterns
- edge loading across the needle crowns when the mating faces are not square to the shaft
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
- abrasive paste forming as dust bypasses the housing seals into the open washer set
- hard-particle indentation where oil or grease filtration is inadequate
- needle-row denting from a single hard particle trapped in the 2 mm section
Selection pitfalls — read before you substitute
- At 80 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 1,700 r/min reference speed is the thermal criterion under load, the 3,400 r/min limiting speed assumes hardened, ground, oiled faces; soft or dry faces drop the real ceiling drastically.
- The 51 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.
- TN polymer and stamped steel cages of the same code (AXK 80105) share envelopes and ratings; the choice is temperature and noise, not load.
- The 51/280 kN ratings and 63 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
How is an AXK thrust assembly mounted?
Harden or washer-face both tracks across Ea 84–Eb 103 mm, keep faces parallel, locate the cage concentrically against a shoulder or register, grease the needles so they stay pocketed, and never press through them.
What are the dimensions and ratings of the AXK 80105?
A AXK 80105 measures 80 mm bore × 105 mm outside diameter × 4 mm width (3.15 × 4.134 × 0.157 in). From SKF catalogue PUB BU/P1 17000: dynamic C 51 kN, static C0 280 kN, fatigue limit Pu 34 kN, reference speed 1,700 r/min, limiting speed 3,400 r/min, mass about 63 g. The contact band runs Ea 84–Eb 103 mm; hardened washers or 58–64 HRC faces are required.
Does the AXK 80105 include washers?
No. AXK is the needle roller and cage thrust assembly only; hardened AS/LS washers or shaft/housing faces at 58–64 HRC, ground over the Ea 84–Eb 103 mm band, supply the two raceways.
How is the AXK 80105 code read?
AXK marks the needle thrust assembly and 80/105 gives the inner 80 mm and outer 105 mm track diameters directly; the assembly is 4 mm thick. TN means the polymer cage instead of stamped steel.
