How the HK6032 model number is decoded
In SKF catalogue PUB BU/P1 17000, HK 6032 denotes a 60×68×32 mm drawn cup needle roller bearing with open ends — the shaft journal is the inner raceway, the pressed shell the outer, and the cage keeps the rollers parallel. Reading the code: HK marks the open-end drawn cup series, the first two digits (60) give the 60 mm under-roller diameter Fw, the last two (32) the 32 mm width; the 68 mm OD follows the ISO 3245 plan. Open caged execution: the standard HK drawn cup with steel cage, relubricable through the shaft where the housing allows. The suffix TN denotes the glass fibre reinforced PA66 cage; the 2RS execution adds rubber contact seals on both faces, retaining factory grease for life-lubricated pivots. The 136 g catalogue mass and 4.0 mm radial section ((68−60)/2) frame a rating of about 0.85 kN dynamic per millimetre of bore — the needle construction's density advantage over ball bearings of the same envelope. The shell is intentionally thin: seat it square with a slow press stroke, support the housing wall behind the bore, and stop the moment the cup face meets the shoulder — hammer blows split drawn cups.
Typical equipment & failure modes
Common applications
- spindle clusters of drilling and tapping units
- auto steering gear rack supports
- clutch release mechanisms and cable pulleys
- office equipment and power tool gear trains
Known failure patterns
- needle edge loading and raceway denting when the shaft deflects beyond the compensation range
- fretting corrosion of the cup outside diameter in a soft or oversized housing bore
- 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
Selection pitfalls — read before you substitute
- Above 50 mm bore, thermal growth matters: the 60 mm inner ring or journal grows with temperature faster than the housing, and the small clearance of a needle roller contact leaves little reserve — check running clearance hot, not just at assembly.
- The quoted 51.2/137 kN ratings are SKF catalogue values for this exact execution (HK 6032); 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 51.2/137 kN ratings and 136 g mass are SKF catalogue values transcribed from ch. 7.2 of PUB BU/P1 17000 (PDF table page 624); combined-type axial ratings appear in the text above because the structured record carries radial values only.
Frequently asked questions
Is the HK 6032 sealed?
No — the open-end HK cup has no seals: the housing must keep contamination out and grease in. The 2RS execution of the same code adds both-side contact seals with a grease fill.
Which dimensions does the HK 6032 have?
A HK 6032 measures 60 mm bore/Fw × 68 mm outside diameter × 32 mm width (2.362 × 2.677 × 1.26 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 51.2 kN, static C0 137 kN, fatigue limit Pu 17 kN, limiting speed 4,800 r/min, reference speed 4,300 r/min, mass about 136 g.
What does HK 6032 mean in SKF part numbering?
HK = open-end drawn cup needle roller bearing (ISO 3245); the first two digits give Fw 60 mm, the last two the width 32 mm, the shell OD 68 mm follows the plan. 2RS adds both-side contact seals, TN the polymer cage.
Does the HK 6032 need a hardened and ground shaft?
No. In this execution the 60 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.
