How the AXK160200 model number is decoded
The AXK assembly AXK 160200 covers 160–200 mm in a 5 mm section and is rated 125 kN dynamic / 1000 kN static: the thinnest rolling thrust support available for that seat. In AXK 160200 the number is the boundary plan, not a bore code: 160/200, with the 5 mm assembly thickness fixed by the ISO 3031 plan and Ea/Eb 166/197 mm marking the actual needle-contact band. The assembly itself has no rings: both raceways must be supplied as hardened washers or machine faces (58–64 HRC, ground), with the contact band covering Ea 166 to Eb 197 mm. Static safety matters for shock duty: compare peak axial force against C0 1000 kN with the application's static factor, since crane hooks and screw positions see their worst load at zero or low speed. Keep the assembly concentric with a shaft shoulder or the housing register — a needle set walking radially off its track is the most common failure; the AXW flanged version removes this risk entirely.
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)
- abrasive paste forming as dust bypasses the housing seals into the open washer set
- electrical erosion of raceways on VFD-driven shafts without grounding or insulation
- 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 (160–200 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 160200) share envelopes and ratings; the choice is temperature and noise, not load.
- The 125 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 160200 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 125/1000 kN ratings and 246 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
How is an AXK thrust assembly mounted?
Harden or washer-face both tracks across Ea 166–Eb 197 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 160200?
A AXK 160200 measures 160 mm bore × 200 mm outside diameter × 5 mm width (6.299 × 7.874 × 0.197 in). From SKF catalogue PUB BU/P1 17000: dynamic C 125 kN, static C0 1000 kN, fatigue limit Pu 106 kN, reference speed 950 r/min, limiting speed 1,900 r/min, mass about 246 g. The contact band runs Ea 166–Eb 197 mm; hardened washers or 58–64 HRC faces are required.
Does the AXK 160200 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 166–Eb 197 mm band, supply the two raceways.
How is the AXK 160200 code read?
AXK marks the needle thrust assembly and 160/200 gives the inner 160 mm and outer 200 mm track diameters directly; the assembly is 5 mm thick. TN means the polymer cage instead of stamped steel.
