How the K15X19X13 model number is decoded
K 15x19x13 is a caged needle roller set, not a complete bearing: paired with a 58–64 HRC ground journal of 15 mm and a housing bore of 19 mm, it forms a full rolling bearing with the smallest possible radial space demand. The designation numbers of K 15x19x13 state the three machine-seat dimensions — 15 mm journal, 19 mm bore-side complement diameter, 13 mm width — which is why ordering errors here show up as a sloppy or seized fit, not as a returned box. 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. Mounting: grind the 15 mm journal to the catalogue raceway tolerance after hardening to 58–64 HRC, bore the housing to E 19 mm H6, and slide the assembly in axially — pressing through the cage distorts it and locks 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
- raceway spalling once the catalogue L10 life is exceeded or after overload events
- cage pocket wear and roller skew after sustained operation with too little radial preload
- abrasive paste formation from dust ingressing past open ends without effective housing seals
- rolling-contact fatigue spalling after the rated L10 life
- smearing of rollers and journal during idle periods because the radial section holds too little lubricant
Selection pitfalls — read before you substitute
- On a 15 mm seat the housing bore quality dominates life: a bore 0.02 mm out of round pinches the 19 mm ring or cup into a lobed shape, and the rollers then trace the housing's geometry error, not the design load.
- Hardness is load capacity: in families without an inner ring the 15 mm journal must hold 58–64 HRC with a ground finish; a surface that looks fine but sits at 45 HRC will rib the raceway within weeks.
- The quoted 8.25/11.2 kN ratings are SKF catalogue values for this exact execution (K 15x19x13); ratings can be revised without the order number changing, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the drawing.
- The 8.25/11.2 kN ratings and 7 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
What limits the service life of a K 15x19x13?
Beyond the L10 rating, the practical limits are journal/raceway hardness for the 15 mm seat, lubricant condition at the roller ends, and contamination through open ends — the 2.0 mm radial section leaves no reserve once a raceway is dented or ribboned.
What are the dimensions and ratings of the K 15x19x13?
A K 15x19x13 measures 15 mm bore/Fw × 19 mm outside diameter × 13 mm width (0.591 × 0.748 × 0.512 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 8.25 kN, static C0 11.2 kN, fatigue limit Pu 1.29 kN, limiting speed 28,000 r/min, reference speed 24,000 r/min, mass about 7 g.
How is the K 15x19x13 designation read?
K = needle roller and cage assembly (DIN 5402); the three figures give Fw 15 mm (shaft journal), E 19 mm (complement outside diameter, matched by the housing bore) and B 13 mm width. TN marks the glass fibre reinforced PA66 cage.
Can the K 15x19x13 run on an unhardened shaft?
No. In this execution the 15 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.
