How the K14X18X17 model number is decoded
SKF catalogue number K 14x18x17 denotes a needle roller and cage assembly for a 14 mm shaft seat — the cage spaces the rollers, the machine parts provide both raceways, and the 17 mm width is all the radial room it needs. K 14×18×17 is a boundary plan, not an envelope: the assembly has no rings, so E 18 mm is the needle set diameter the housing bore must match, and the 14 mm journal must be ground and hardened. No suffix on the order number means the standard single-row assembly; the polymer TN cage version is the usual choice for grease-lubricated pivots where noise matters. Minimum load matters: below roughly 0.02·C the rollers skid and smear; preloading the pivot or specifying a heavier execution avoids the glazing that pure oscillation produces on these raceways. The assembly is drawn on over a mounting sleeve that spreads the load around all rollers; never drive it home against the cage face, and retain it with a washer whose OD spans the cage, not the rollers.
Typical equipment & failure modes
Common applications
- universal joint crosses on commercial vehicles
- planetary gear pins in compact transmissions
- connecting rods of small compressors where radial height is critical
- rocker arm and rocker pin pivots on camshafts
Known failure patterns
- needle edge loading and raceway denting when the shaft deflects beyond the compensation range
- polymer cage deformation when the local temperature exceeds the 120 °C sustained limit
- abrasive paste formation from dust ingressing past open ends without effective housing seals
- brinelling of raceways from impact or pressing force transmitted through the rolling elements
- rapid raceway scoring when the shaft journal hardness drops below 58 HRC or the ground finish wears away
Selection pitfalls — read before you substitute
- On a 14 mm seat the housing bore quality dominates life: a bore 0.02 mm out of round pinches the 18 mm ring or cup into a lobed shape, and the rollers then trace the housing's geometry error, not the design load.
- The quoted 10.5/14.6 kN ratings are SKF catalogue values for this exact execution (K 14x18x17); ratings can be revised without the order number changing, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the drawing.
- Oscillating pivots fail differently: rocking through a small angle concentrates wear in the same roller positions — inspect those zones, and consider rotating the assembly's clock position at service intervals.
- The 10.5/14.6 kN ratings and 8 g mass are SKF catalogue values transcribed from ch. 7.1 of PUB BU/P1 17000 (PDF table page 616); combined-type axial ratings appear in the text above because the structured record carries radial values only.
Frequently asked questions
Which dimensions does the K 14x18x17 have?
A K 14x18x17 measures 14 mm bore/Fw × 18 mm outside diameter × 17 mm width (0.551 × 0.709 × 0.669 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 10.5 kN, static C0 14.6 kN, fatigue limit Pu 1.7 kN, limiting speed 28,000 r/min, reference speed 24,000 r/min, mass about 8 g.
What does K 14x18x17 mean in SKF part numbering?
K = needle roller and cage assembly (DIN 5402); the three figures give Fw 14 mm (shaft journal), E 18 mm (complement outside diameter, matched by the housing bore) and B 17 mm width. TN marks the glass fibre reinforced PA66 cage.
Does the K 14x18x17 need a hardened and ground shaft?
No. In this execution the 14 mm shaft journal is the inner raceway: it must be ground and hardened to 58–64 HRC (with matching housing bore quality on the outside). If the shaft cannot meet that, order the inner-ring sibling (NKI/NA execution) plus its ground inner ring instead.
What mounting mistakes ruin a K 14x18x17?
Slide the assembly over the ground 14 mm journal with a mounting sleeve, bore the housing to E 18 mm, and retain with a washer spanning the cage. Never press against the cage or rotate before the bearing is lubricated and loaded.
