Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| HK4016 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 40×47×16 mm envelope, but catalogue C/C0 differ between the executions (14.5/27.5 vs 19/39 kN) — boundary dimensions match, not a load-rating equivalent. |

How the HK4016-2RS model number is decoded
In SKF catalogue PUB BU/P1 17000, HK 4016.2RS denotes a 40×47×16 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 (40) give the 40 mm under-roller diameter Fw, the last two (16) the 16 mm width; the 47 mm OD follows the ISO 3245 plan. Sealed 2RS execution: rubber contact seals on both cup faces, factory grease fill, and the slightly lower ratings of a sealed drawn cup — 14.5 kN C against the open bearing of the same code. Caged HK bearings space the rollers for lower friction than full complement HK types; the cage is not a seal — 2RS executions are the sealed members of the family. Selection arithmetic: C 14.5 kN against C0 27.5 kN gives a C0/C ratio of 1.90, and the 3.15 kN fatigue load limit Pu sets the floor for the adjusted-life calculation at contaminated lubrication. 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
- steering column and pedal-box pivots in passenger cars
- idler gears and pulleys in small appliance drives
- spindle clusters of drilling and tapping units
- auto steering gear rack supports
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
- abrasive paste formation from dust ingressing past open ends without effective housing seals
- brinelling of raceways from impact or pressing force transmitted through the rolling elements
Selection pitfalls — read before you substitute
- At 40 mm bore, verify shaft deflection against the needle length: these rollers tolerate little edge loading, and a simply supported span between 40 mm seats can bend past the compensation range long before the load rating is exhausted.
- The quoted 14.5/27.5 kN ratings are SKF catalogue values for this exact execution (HK 4016.2RS); 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 14.5/27.5 kN ratings and 37 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
Which dimensions does the HK 4016.2RS have?
A HK 4016.2RS measures 40 mm bore/Fw × 47 mm outside diameter × 16 mm width (1.575 × 1.85 × 0.63 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 14.5 kN, static C0 27.5 kN, fatigue limit Pu 3.15 kN, limiting speed 4,500 r/min, mass about 37 g.
What does HK 4016.2RS mean in SKF part numbering?
HK = open-end drawn cup needle roller bearing (ISO 3245); the first two digits give Fw 40 mm, the last two the width 16 mm, the shell OD 47 mm follows the plan. 2RS adds both-side contact seals, TN the polymer cage.
Does the HK 4016.2RS need a hardened and ground shaft?
No. In this execution the 40 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 HK 4016.2RS?
Press the cup in with a shouldered mandrel bearing on the stamped face, into a housing bore sized for a firm press fit; never hammer it or press through the rollers. Then slide the hardened shaft in. For 2RS executions the seals and grease are already in place — no additional sealing is needed.
