How the AXK0414-TN model number is decoded
In SKF catalogue PUB BU/P1 17000, AXK 0414 TN denotes the needle thrust assembly whose code reads the raceway diameters directly — 04/14 — intended to run against hardened, ground washers or machine faces. In AXK 0414 TN the number is the boundary plan, not a bore code: 04/14, with the 2 mm assembly thickness fixed by the ISO 3031 plan and Ea/Eb 5/13 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. Static safety matters for shock duty: compare peak axial force against C0 8.3 kN with the application's static factor, since crane hooks and screw positions see their worst load at zero or low speed. Mounting: harden and grind both mating faces to 58–64 HRC over the full Ea 5–Eb 13 mm band (or fit AS/LS washers), drop the 2 mm cage in flat, and never press or hammer the needle complement.
Typical equipment & failure modes
Common applications
- 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
- torque converter and clutch release assemblies in passenger cars
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)
- oil starvation at the sliding contact zones of large spherical roller thrust bearings on forced-feed trips
- rolling-contact fatigue spalling after the catalogue L10 life is exhausted
- 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 0414 TN is watchmaking-scale (2 mm thick, 0.7 g): handle it with tweezers, grease it onto its washer, and assume one dropped or cocked assembly is one ruined bearing.
- 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.
- TN polymer and stamped steel cages of the same code (AXK 0414) share envelopes and ratings; the choice is temperature and noise, not load.
- The 4.15 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.
- The AXK code supplies no washers: AXK 0414 TN 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 4.15/8.3 kN ratings and 0.7 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
Does the AXK 0414 TN 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 5–Eb 13 mm band, supply the two raceways.
How is the AXK 0414 TN code read?
AXK marks the needle thrust assembly and 04/14 gives the inner 4 mm and outer 14 mm track diameters directly; the assembly is 2 mm thick. TN means the polymer cage instead of stamped steel.
What minimum hardness do the mating faces need?
58–64 HRC with a ground raceway finish. A softer face looks fine after assembly but the needles rib and score it within weeks despite the 4.15 kN catalogue rating — order certified washers if the shaft/housing cannot be heat treated.
How is an AXK thrust assembly mounted?
Harden or washer-face both tracks across Ea 5–Eb 13 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.
