Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| HK3016 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 30×37×16 mm envelope, but catalogue C/C0 differ between the executions (11.7/18.3 vs 16.5/29 kN) — boundary dimensions match, not a load-rating equivalent. |

How the HK3016-2RS model number is decoded
HK 3016.2RS is an open-end drawn cup needle roller bearing to ISO 3245: a hardened, thin-walled shell of 37 mm outside diameter carrying a caged needle roller set for a 30 mm shaft, listed by SKF in SKF catalogue PUB BU/P1 17000. In HK 3016, Fw = 30 mm names the shaft that becomes the inner raceway and B = 16 mm the cup width; the shell outside diameter 37 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 — 11.7 kN C against the open bearing of the same code. The shell itself is the outer ring: hardened sheet steel, closed at neither end (open type), so the shaft can pass through and lubricant can be fed axially along the journal. The 31 g catalogue mass and 3.5 mm radial section ((37−30)/2) frame a rating of about 0.39 kN dynamic per millimetre of bore — the needle construction's density advantage over ball bearings of the same envelope. 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 16 mm section.
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
- raceway spalling once the catalogue L10 life is exceeded or after overload events
- drawn-cup shell distortion or splitting from a careless press-in without a seating mandrel
- grease starvation at the roller ends when relubrication intervals are stretched in dirty duty
- electrical erosion on VFD-driven shafts without brush or insulated mounting
Selection pitfalls — read before you substitute
- At 30 mm bore, verify shaft deflection against the needle length: these rollers tolerate little edge loading, and a simply supported span between 30 mm seats can bend past the compensation range long before the load rating is exhausted.
- 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.
- Contamination, not fatigue, kills most small needle bearings: with raceways this narrow, one hard particle dents a full-width line — seal the housing even when the bearing execution itself is open.
- The 11.7/18.3 kN ratings and 31 g mass are SKF catalogue values transcribed from ch. 7.2 of PUB BU/P1 17000 (PDF table page 622); combined-type axial ratings appear in the text above because the structured record carries radial values only.
Frequently asked questions
What are the dimensions and ratings of the HK 3016.2RS?
A HK 3016.2RS measures 30 mm bore/Fw × 37 mm outside diameter × 16 mm width (1.181 × 1.457 × 0.63 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 11.7 kN, static C0 18.3 kN, fatigue limit Pu 2.12 kN, limiting speed 5,600 r/min, mass about 31 g.
How is the HK 3016.2RS designation read?
HK = open-end drawn cup needle roller bearing (ISO 3245); the first two digits give Fw 30 mm, the last two the width 16 mm, the shell OD 37 mm follows the plan. 2RS adds both-side contact seals, TN the polymer cage.
Can the HK 3016.2RS run on an unhardened shaft?
No. In this execution the 30 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.
How should the HK 3016.2RS be mounted?
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.
