How the K10X16X12-TN model number is decoded
In SKF catalogue PUB BU/P1 17000 ch. 7.1, K 10x16x12 TN appears as a needle roller and cage assembly with complement diameter E 16 mm and width 12 mm — a self-contained roller set that turns a 10 mm shaft and its housing into a complete bearing. Reading the designation: K marks the needle roller and cage assembly, the three numbers give Fw 10 (shaft journal), E 16 (assembly outside diameter) and B 12 (width) in millimetres — the machine parts complete the bearing. 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. Lubrication reaches both raceways through the open cage windows; grease the bore and journal before assembly, since after fitting the 12 mm narrow cage cannot be relubricated through a closed housing.
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
- hard-particle indentation in unfiltered lubricant
- 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 16 mm ring or cup into a lobed shape, and the rollers then trace the housing's geometry error, not the design load.
- The quoted 7.65/7.2 kN ratings are SKF catalogue values for this exact execution (K 10x16x12 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 7.65/7.2 kN ratings and 5.5 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
Which dimensions does the K 10x16x12 TN have?
A K 10x16x12 TN measures 10 mm bore/Fw × 16 mm outside diameter × 12 mm width (0.394 × 0.63 × 0.472 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 7.65 kN, static C0 7.2 kN, fatigue limit Pu 0.85 kN, limiting speed 32,000 r/min, reference speed 28,000 r/min, mass about 5.5 g.
What does K 10x16x12 TN mean in SKF part numbering?
K = needle roller and cage assembly (DIN 5402); the three figures give Fw 10 mm (shaft journal), E 16 mm (complement outside diameter, matched by the housing bore) and B 12 mm width. TN marks the glass fibre reinforced PA66 cage.
Does the K 10x16x12 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 10x16x12 TN?
Slide the assembly over the ground 10 mm journal with a mounting sleeve, bore the housing to E 16 mm, and retain with a washer spanning the cage. Never press against the cage or rotate before the bearing is lubricated and loaded.
