How the K10X14X10-TN model number is decoded
In SKF catalogue PUB BU/P1 17000 ch. 7.1, K 10x14x10 TN appears as a needle roller and cage assembly with complement diameter E 14 mm and width 10 mm — a self-contained roller set that turns a 10 mm shaft and its housing into a complete bearing. In the K code K 10x14x10 TN, Fw×E×B reads directly as journal 10 mm, complement diameter 14 mm and cage width 10 mm; the housing bore is ground to E with H6/H7 tolerance to complete the outer raceway. Because there are no rings, execution differences live in the cage: TN polymer cages reduce friction and noise, while the basic steel cage tolerates higher operating temperatures up to the lubricant limit. Catalogue mass 2.5 g at 10×14×10 mm makes this one of the highest capacity-per-gram choices in the needle roller and cage assemblies; the limit is usually the shaft's ability to serve as a raceway, not the rolling contact itself. Mounting: grind the 10 mm journal to the catalogue raceway tolerance after hardening to 58–64 HRC, bore the housing to E 14 mm H6, and slide the assembly in axially — pressing through the cage distorts it and locks the rollers.
Typical equipment & failure modes
Common applications
- planetary gear pins in compact transmissions
- connecting rods of small compressors where radial height is critical
- rocker arm and rocker pin pivots on camshafts
- pump and gearbox idler gears running on hardened pins
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
- abrasive paste formation from dust ingressing past open ends without effective housing seals
- corrosion pitting from condensation in intermittently operated machinery
- 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 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.
- Hardness is load capacity: in families without an inner ring the 10 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 5.61/6.1 kN ratings are SKF catalogue values for this exact execution (K 10x14x10 TN); ratings can be revised without the order number changing, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the drawing.
- The 5.61/6.1 kN ratings and 2.5 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 10x14x10 TN?
A K 10x14x10 TN measures 10 mm bore/Fw × 14 mm outside diameter × 10 mm width (0.394 × 0.551 × 0.394 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 5.61 kN, static C0 6.1 kN, fatigue limit Pu 0.695 kN, limiting speed 32,000 r/min, reference speed 28,000 r/min, mass about 2.5 g.
How is the K 10x14x10 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 10 mm width. TN marks the glass fibre reinforced PA66 cage.
Can the K 10x14x10 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 10x14x10 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.
