How the K10X14X13-TN model number is decoded
SKF catalogue number K 10x14x13 TN denotes a needle roller and cage assembly for a 10 mm shaft seat — the cage spaces the rollers, the machine parts provide both raceways, and the 13 mm width is all the radial room it needs. The designation numbers of K 10x14x13 TN state the three machine-seat dimensions — 10 mm journal, 14 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. SKF supplies these assemblies in single rows as tabulated; the cage quality determines the speed ceiling, and the catalogued 32,000 r/min limiting speed assumes a precision ground journal and bore. For life calculation, the 7.21/8.5 kN ratings assume raceway geometry supplied by the shaft and housing in families without an inner ring — journal hardness, roundness and finish are part of the bearing, not of the application. 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
- hinge and pivot joints in printing and textile machinery
- universal joint crosses on commercial vehicles
- planetary gear pins in compact transmissions
- connecting rods of small compressors where radial height is critical
Known failure patterns
- raceway spalling once the catalogue L10 life is exceeded or after overload events
- polymer cage deformation when the local temperature exceeds the 120 °C sustained limit
- grease starvation at the roller ends when relubrication intervals are stretched in dirty duty
- brinelling of raceways from impact or pressing force transmitted through the rolling elements
- smearing of rollers and journal during idle periods because the radial section holds too little lubricant
Selection pitfalls — read before you substitute
- On a 10 mm seat the housing bore quality dominates life: a bore 0.02 mm out of round pinches the 14 mm ring or cup into a lobed shape, and the rollers then trace the housing's geometry error, not the design load.
- Do not interchange envelope-identical needle families blindly: K 10x14x13 TN shares its 10×14×13 mm outline with inner-ring and sealed siblings whose ratings differ — the family letters are part of the specification, not decoration.
- Reference and limiting speeds are different limits: the 28,000 r/min reference is the thermal criterion under load, The limiting value is mechanical; the reference value is thermal under load, and grease choice moves it substantially.
- The 7.21/8.5 kN ratings and 4.6 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 are the dimensions and ratings of the K 10x14x13 TN?
A K 10x14x13 TN measures 10 mm bore/Fw × 14 mm outside diameter × 13 mm width (0.394 × 0.551 × 0.512 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 7.21 kN, static C0 8.5 kN, fatigue limit Pu 0.98 kN, limiting speed 32,000 r/min, reference speed 28,000 r/min, mass about 4.6 g.
How is the K 10x14x13 TN designation read?
K = needle roller and cage assembly (DIN 5402); the three figures give Fw 10 mm (shaft journal), E 14 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 10x14x13 TN run on an unhardened shaft?
No. In this execution the 10 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.
How should the K 10x14x13 TN be mounted?
Slide the assembly over the ground 10 mm journal with a mounting sleeve, bore the housing to E 14 mm, and retain with a washer spanning the cage. Never press against the cage or rotate before the bearing is lubricated and loaded.
