How the AXW35 model number is decoded
AXW 35 is the assembly-friendly pairing of an AXK 3552 cage with a spigot washer: cage and washer arrive pre-centred as one part at 35×55 mm, 3.2 mm total height. The designation AXW 35 reads as flanged (AXW) needle thrust for a 35 mm shaft — the spigot pilots in the 42 mm housing register, not on the shaft. The integrated washer carries a 42 mm centring spigot (4 mm flange height) that locates the whole unit in a matching housing register bore — the 35 mm bore clears the shaft and does no radial piloting. One direction only: AXW 35 cannot be reversed to take opposite thrust — mirror a second bearing for reversing shafts, and keep housing and shaft seats square within the ISO 104 tolerances. Press only on the washer back — never on the spigot lip or through the needle cage — keep the register free of burrs, and verify the unit turns without the flange rubbing its register.
Typical equipment & failure modes
Common applications
- material-handling swivel joints using the spigot as a built-in housing pilot
- transmission shafts where a one-piece spigot-centred thrust unit replaces a loose cage-and-washer stack at the housing register
- automotive selector and shift mechanisms needing a pre-centred flanged thrust support in a shallow housing bore
- agricultural gear drives assembled through a housing cover, where the spigot keeps the needle set concentric until the cover is bolted
Known failure patterns
- spigot lip deformation after a hammer blow or cocked assembly at fitting
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
- needle-row denting from a single hard particle trapped in the 2 mm section
- brinelling of washer raceways from impact or mounting force applied through the rolling elements
Selection pitfalls — read before you substitute
- At 35 mm, verify the opposite raceway face — the integrated spigot washer supplies one side only; a soft face or missing LS/AS washer on the other ribs within months.
- the 3,200 r/min reference speed is the thermal criterion under load, limiting speed 6,300 r/min; the open needle set needs the housing to keep grit out.
- One-direction thrust: reversing force dumps the needles off the 51 mm outer track — mirror a second spigot-flanged unit where the load reverses.
- The spigot pilots in the housing register, not on the shaft: turning the 35 mm bore into a tight pilot fit, or omitting the 42 mm register bore, defeats the centring function of AXW 35.
- AXW is not an ISO-standardized interchangeable outline for every maker — check the 55×3.2 mm envelope and the 42 mm spigot before cross-brand substitution.
- The 16.6/83 kN ratings and 27 g mass are SKF catalogue values transcribed from ch. 12.2 of PUB BU/P1 17000 (PDF table page 912); mounting data — Ea/Eb raceway diameters, the flange register and the load factor — appears in the running text because the structured record carries the boundary envelope only.
Frequently asked questions
What is the centring spigot on the AXW 35 for?
The 42 mm diameter, 4 mm high spigot locates the bearing in a matching housing register and centres the needle set radially; it does not pilot on the 35 mm shaft.
How is the AXW 35 designation read?
AXW marks the spigot-flanged needle roller thrust bearing and 35 is the bore in millimetres; the series plan fixes the 55 mm OD and 3.2 mm overall height, D1 42 mm is the spigot, and the AXK 3552 needle set runs inside.
Does the AXW 35 still need hardened faces?
The integrated spigot washer is one hardened raceway, but the opposing face is the application's responsibility — fit a separate LS/AS washer or harden it to 58–64 HRC over Ea 39–Eb 51 mm.
How is an AXW bearing mounted?
Locate the 42 mm spigot in the housing register bore, pass the 35 mm bore over the shaft without a pilot fit, fit a separate LS/AS washer or a 58–64 HRC face on the opposite side, and press via the washer back only.
