How the K35X42X16 model number is decoded
For pivots and crank pins where every millimetre of radial height counts, SKF supplies K 35x42x16: needle rollers in a pressed cage (DIN 5402 boundary plan), dimensioned Fw 35 × E 42 × B 16 mm. K 35×42×16 is a boundary plan, not an envelope: the assembly has no rings, so E 42 mm is the needle set diameter the housing bore must match, and the 35 mm journal must be ground and hardened. The TN suffix marks a glass fibre reinforced PA66 cage snapping the rollers in place — lighter and quieter than steel; assemblies are also supplied unmarked with steel cages for higher temperature duty. For life calculation, the 23.3/37.5 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. Mounting: grind the 35 mm journal to the catalogue raceway tolerance after hardening to 58–64 HRC, bore the housing to E 42 mm H6, and slide the assembly in axially — pressing through the cage distorts it and locks 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
- 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
- At 35 mm bore, verify shaft deflection against the needle length: these rollers tolerate little edge loading, and a simply supported span between 35 mm seats can bend past the compensation range long before the load rating is exhausted.
- Reference and limiting speeds are different limits: the 11,000 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.
- Hardness is load capacity: in families without an inner ring the 35 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 23.3/37.5 kN ratings and 34 g mass are SKF catalogue values transcribed from ch. 7.1 of PUB BU/P1 17000 (PDF table page 618); combined-type axial ratings appear in the text above because the structured record carries radial values only.
Frequently asked questions
Is the K 35x42x16 sealed?
No — this execution is open and depends on the housing sealing arrangement; grease it at assembly and keep the relubrication interval short in dirty duty.
Which dimensions does the K 35x42x16 have?
A K 35x42x16 measures 35 mm bore/Fw × 42 mm outside diameter × 16 mm width (1.378 × 1.654 × 0.63 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 23.3 kN, static C0 37.5 kN, fatigue limit Pu 4.5 kN, limiting speed 13,000 r/min, reference speed 11,000 r/min, mass about 34 g.
What does K 35x42x16 mean in SKF part numbering?
K = needle roller and cage assembly (DIN 5402); the three figures give Fw 35 mm (shaft journal), E 42 mm (complement outside diameter, matched by the housing bore) and B 16 mm width. TN marks the glass fibre reinforced PA66 cage.
Does the K 35x42x16 need a hardened and ground shaft?
No. In this execution the 35 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.
