How the AXK130170 model number is decoded
The AXK assembly AXK 130170 covers 130–170 mm in a 5 mm section and is rated 112 kN dynamic / 830 kN static: the thinnest rolling thrust support available for that seat. In AXK 130170 the number is the boundary plan, not a bore code: 130/170, with the 5 mm assembly thickness fixed by the ISO 3031 plan and Ea/Eb 136/167 mm marking the actual needle-contact band. Washer selection is part of the bearing: too-soft faces rib within weeks even though the 112 kN rating is unchanged — the AXK code only supplies the rolling elements. Selection arithmetic: C 112 kN against C0 830 kN gives a C0/C ratio of 7.41 — thrust bearings are chosen on static rating and F_a/C0 more often than on L10 life. Mounting: harden and grind both mating faces to 58–64 HRC over the full Ea 136–Eb 167 mm band (or fit AS/LS washers), drop the 5 mm cage in flat, and never press or hammer the needle complement.
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
- needle-row denting from a single hard particle trapped in the 2 mm section
- 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
- 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
- Above 110 mm the large AXK sets (130–170 mm) are assembled standing up in vertical gearboxes — retain the cage or it walks off its track before the first bolt is torqued.
- 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.
- TN polymer and stamped steel cages of the same code (AXK 130170) share envelopes and ratings; the choice is temperature and noise, not load.
- The AXK code supplies no washers: AXK 130170 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 130–170 mm track — a washer sized to the shaft alone leaves the needles overrunning its edge, which shears the cage.
- The 112/830 kN ratings and 205 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
What are the dimensions and ratings of the AXK 130170?
A AXK 130170 measures 130 mm bore × 170 mm outside diameter × 5 mm width (5.118 × 6.693 × 0.197 in). From SKF catalogue PUB BU/P1 17000: dynamic C 112 kN, static C0 830 kN, fatigue limit Pu 93 kN, reference speed 1,100 r/min, limiting speed 2,200 r/min, mass about 205 g. The contact band runs Ea 136–Eb 167 mm; hardened washers or 58–64 HRC faces are required.
Does the AXK 130170 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 136–Eb 167 mm band, supply the two raceways.
How is the AXK 130170 code read?
AXK marks the needle thrust assembly and 130/170 gives the inner 130 mm and outer 170 mm track diameters directly; the assembly is 5 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 112 kN catalogue rating — order certified washers if the shaft/housing cannot be heat treated.
