How the HK1014-2RS model number is decoded
SKF supplies HK 1014.2RS for housings where machining an outer-ring pocket is uneconomical: the 14 mm shell broached from sheet steel press-fits into a plain bore and runs a 10 mm hardened shaft. In HK 1014, Fw = 10 mm names the shaft that becomes the inner raceway and B = 14 mm the cup width; the shell outside diameter 14 mm is fixed by the boundary plan, so the housing bore needs only a press-fit tolerance. Sealed 2RS execution: rubber contact seals on both cup faces, factory grease fill, and the slightly lower ratings of a sealed drawn cup — 4.29 kN C against the open bearing of the same code. Drawn cups exist open (basic HK), sealed (2RS, with contact seals and grease fill) and with polymer TN cage; each is a separate order number with its own ratings, not a field conversion. Catalogue mass 4.6 g at 10×14×14 mm makes this one of the highest capacity-per-gram choices in the drawn cup needle roller bearings, open end; the limit is usually the shaft's ability to serve as a raceway, not the rolling contact itself. Open ends mean the housing must do the sealing; where that is impossible, the 2RS execution with its integrated seals and grease fill replaces sealing rings that would not fit the 14 mm section.
Typical equipment & failure modes
Common applications
- office equipment and power tool gear trains
- steering column and pedal-box pivots in passenger cars
- idler gears and pulleys in small appliance drives
- spindle clusters of drilling and tapping units
Known failure patterns
- raceway spalling once the catalogue L10 life is exceeded or after overload events
- fretting corrosion of the cup outside diameter in a soft or oversized housing bore
- abrasive paste formation from dust ingressing past open ends without effective housing seals
- hard-particle indentation in unfiltered lubricant
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 4.29/5.3 kN ratings are SKF catalogue values for this exact execution (HK 1014.2RS); ratings can be revised without the order number changing, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the drawing.
- The 4.29/5.3 kN ratings and 4.6 g mass are SKF catalogue values transcribed from ch. 7.2 of PUB BU/P1 17000 (PDF table page 620); combined-type axial ratings appear in the text above because the structured record carries radial values only.
Frequently asked questions
What limits the service life of a HK 1014.2RS?
Beyond the L10 rating, the practical limits are journal/raceway hardness for the 10 mm seat, lubricant condition at the roller ends, and contamination through open ends — the 2.0 mm radial section leaves no reserve once a raceway is dented or ribboned.
What are the dimensions and ratings of the HK 1014.2RS?
A HK 1014.2RS measures 10 mm bore/Fw × 14 mm outside diameter × 14 mm width (0.394 × 0.551 × 0.551 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 4.29 kN, static C0 5.3 kN, fatigue limit Pu 0.57 kN, limiting speed 12,000 r/min, mass about 4.6 g.
How is the HK 1014.2RS designation read?
HK = open-end drawn cup needle roller bearing (ISO 3245); the first two digits give Fw 10 mm, the last two the width 14 mm, the shell OD 14 mm follows the plan. 2RS adds both-side contact seals, TN the polymer cage.
Can the HK 1014.2RS 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.
