How the AXK0619-TN model number is decoded
AXK 0619 TN is a needle roller and cage thrust assembly to ISO 3031: a 2 mm thin cage packing the maximum number of small needles for a 6 mm shaft raceway and 19 mm outside track, as listed in SKF catalogue PUB BU/P1 17000 ch. 12.1. The designation AXK 0619 TN identifies a 2 mm needle thrust cage for the 6–19 mm track; the same diameters select the matching hardened washers, which is the usual ordering error to avoid. Washer selection is part of the bearing: too-soft faces rib within weeks even though the 6.3 kN rating is unchanged — the AXK code only supplies the rolling elements. No factor A is published for needle thrust sets: keep a light preload so the needles roll rather than skid — springs, shim preload or the gear's own backlash take-up are part of the selection, not an accessory. 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
- small gearbox gears that need a 2 mm thrust shim between a shaft and face
- light turntables, index plates and office-machine pivots
- two-wheeler gearbox selector and layshaft thrust faces
- compact drives where hardened washers replace a machined raceway shoulder
Known failure patterns
- needle-row denting from a single hard particle trapped in the 2 mm section
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
- grease churning and overheating when a high-speed thrust position is over-packed
- 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
- The AXK 0619 TN is watchmaking-scale (2 mm thick, 1 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 0619) share envelopes and ratings; the choice is temperature and noise, not load.
- Match washers by the exact 6–19 mm track — a washer sized to the shaft alone leaves the needles overrunning its edge, which shears the cage.
- the 6,000 r/min reference speed is the thermal criterion under load, the 12,000 r/min limiting speed assumes hardened, ground, oiled faces; soft or dry faces drop the real ceiling drastically.
- The 6.3/16 kN ratings and 1 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
What are the dimensions and ratings of the AXK 0619 TN?
A AXK 0619 TN measures 6 mm bore × 19 mm outside diameter × 2 mm width (0.236 × 0.748 × 0.079 in). From SKF catalogue PUB BU/P1 17000: dynamic C 6.3 kN, static C0 16 kN, fatigue limit Pu 1.86 kN, reference speed 6,000 r/min, limiting speed 12,000 r/min, mass about 1 g. The contact band runs Ea 7–Eb 18 mm; hardened washers or 58–64 HRC faces are required.
Does the AXK 0619 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 7–Eb 18 mm band, supply the two raceways.
How is the AXK 0619 TN code read?
AXK marks the needle thrust assembly and 06/19 gives the inner 6 mm and outer 19 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 6.3 kN catalogue rating — order certified washers if the shaft/housing cannot be heat treated.
