How the K10X13X10-TN model number is decoded
SKF lists K 10x13x10 TN in the K series of needle roller and cage assemblies: needle rollers caged at 10×13×10 mm, designed to run directly on a ground, hardened shaft and inside a machined housing bore. Reading the designation: K marks the needle roller and cage assembly, the three numbers give Fw 10 (shaft journal), E 13 (assembly outside diameter) and B 10 (width) in millimetres — the machine parts complete the bearing. 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. Catalogue mass 1.6 g at 10×13×10 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 13 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
- needle edge loading and raceway denting when the shaft deflects beyond the compensation range
- cage pocket wear and roller skew after sustained operation with too little radial preload
- grease starvation at the roller ends when relubrication intervals are stretched in dirty duty
- rolling-contact fatigue spalling after the rated L10 life
- 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 13 mm ring or cup into a lobed shape, and the rollers then trace the housing's geometry error, not the design load.
- The quoted 4.57/5.7 kN ratings are SKF catalogue values for this exact execution (K 10x13x10 TN); 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 4.57/5.7 kN ratings and 1.6 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
Which dimensions does the K 10x13x10 TN have?
A K 10x13x10 TN measures 10 mm bore/Fw × 13 mm outside diameter × 10 mm width (0.394 × 0.512 × 0.394 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 4.57 kN, static C0 5.7 kN, fatigue limit Pu 0.63 kN, limiting speed 32,000 r/min, reference speed 28,000 r/min, mass about 1.6 g.
What does K 10x13x10 TN mean in SKF part numbering?
K = needle roller and cage assembly (DIN 5402); the three figures give Fw 10 mm (shaft journal), E 13 mm (complement outside diameter, matched by the housing bore) and B 10 mm width. TN marks the glass fibre reinforced PA66 cage.
Does the K 10x13x10 TN need a hardened and ground 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.
What mounting mistakes ruin a K 10x13x10 TN?
Slide the assembly over the ground 10 mm journal with a mounting sleeve, bore the housing to E 13 mm, and retain with a washer spanning the cage. Never press against the cage or rotate before the bearing is lubricated and loaded.
