How the AXW10 model number is decoded
In the AXW needle roller thrust bearings with centring flange, AXW 10 denotes the spigot-centred execution: the flange seats in a matching housing register so the needle set stays concentric without piloting on the shaft, and the opposite raceway is a separate LS/AS washer or a hardened machine face. Reading the code: AXW marks the spigot-flanged needle roller thrust bearing and the figure 10 gives the bore in millimetres; the 27 mm OD and 3.2 mm height follow the series plan, and D1 14 mm is the spigot diameter. The integrated washer carries a 14 mm centring spigot (3 mm flange height) that locates the whole unit in a matching housing register bore — the 10 mm bore clears the shaft and does no radial piloting. One direction only: AXW 10 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. Mounting: locate the 14 mm spigot in the housing register bore (at least 3 mm deep), pass the 10 mm bore over the shaft without forcing a pilot fit, and fit a separate LS/AS washer or a hardened 58–64 HRC face on the opposite side.
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
- edge loading across the needle crowns when the mating faces are not square to the shaft
- rolling-contact fatigue spalling after the catalogue L10 life is exhausted
Selection pitfalls — read before you substitute
- At 10 mm bore the 14 mm spigot lip is thin enough to bend with pliers — handle AXW 10 by the washer face, never by the flange.
- AXW is not an ISO-standardized interchangeable outline for every maker — check the 27×3.2 mm envelope and the 14 mm spigot before cross-brand substitution.
- The 8.5 kN rating still requires a hardened opposing face: the integrated washer is one raceway only, and the other track is a separate LS/AS washer or a 58–64 HRC machine face.
- The spigot pilots in the housing register, not on the shaft: turning the 10 mm bore into a tight pilot fit, or omitting the 14 mm register bore, defeats the centring function of AXW 10.
- the 5,300 r/min reference speed is the thermal criterion under load, limiting speed 10,000 r/min; the open needle set needs the housing to keep grit out.
- The 8.5/26 kN ratings and 8.3 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
Can the AXW 10 take radial load?
No. The spigot is a locating pilot, not a radial bearing: the needle set carries one-direction thrust (8.5 kN dynamic) and the shaft arrangement carries all radial force.
Does the AXW 10 run in both axial directions?
No — one direction only. Reversing thrust lifts the needles off the 23 mm outer track; mirror a second spigot-flanged unit for reversing shafts.
What are the common mounting mistakes?
Pressing on the spigot lip, boring no register (or a wrong-size 14 mm register) in the housing, forcing the 10 mm bore into a pilot fit, leaving the opposite face soft, or skipping grease in the 3.2 mm section — each shows up as cage or track damage within hours.
Which dimensions does the AXW 10 have?
A AXW 10 measures 10 mm bore × 27 mm outside diameter × 3.2 mm width (0.394 × 1.063 × 0.126 in). From SKF catalogue PUB BU/P1 17000: dynamic C 8.5 kN, static C0 26 kN, fatigue limit Pu 3 kN, reference speed 5,300 r/min, limiting speed 10,000 r/min, mass about 8.3 g. Centring spigot D1 14 mm, spigot height B1 3 mm, contact band Ea 12–23 mm.
