Cross references & equivalents
| Equivalent model | Brand | Match level | Note |
|---|---|---|---|
| HK2016 | SKF | partial Main dimensions match; tolerances, seals or internal clearance differ. | Same 20×26×16 mm envelope, but catalogue C/C0 differ between the executions (8.42/12.5 vs 12.3/20.4 kN) — boundary dimensions match, not a load-rating equivalent. |

How the HK2016-2RS model number is decoded
HK 2016.2RS is an open-end drawn cup needle roller bearing to ISO 3245: a hardened, thin-walled shell of 26 mm outside diameter carrying a caged needle roller set for a 20 mm shaft, listed by SKF in SKF catalogue PUB BU/P1 17000. The designation HK 2016.2RS encodes geometry only — there is no bore code to decode, since the 20 mm Fw is printed directly in the first digits and the cup width 16 mm in the last two. Sealed 2RS execution: rubber contact seals on both cup faces, factory grease fill, and the slightly lower ratings of a sealed drawn cup — 8.42 kN C against the open bearing of the same code. 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. Minimum load matters: below roughly 0.02·C the rollers skid and smear; preloading the pivot or specifying a heavier execution avoids the glazing that pure oscillation produces on these raceways. 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
- clutch release mechanisms and cable pulleys
- office equipment and power tool gear trains
- steering column and pedal-box pivots in passenger cars
- idler gears and pulleys in small appliance drives
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
- On a 20 mm seat the housing bore quality dominates life: a bore 0.02 mm out of round pinches the 26 mm ring or cup into a lobed shape, and the rollers then trace the housing's geometry error, not the design load.
- 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.
- Do not interchange envelope-identical needle families blindly: HK 2016.2RS shares its 20×26×16 mm outline with inner-ring and sealed siblings whose ratings differ — the family letters are part of the specification, not decoration.
- The 8.42/12.5 kN ratings and 18 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
Which dimensions does the HK 2016.2RS have?
A HK 2016.2RS measures 20 mm bore/Fw × 26 mm outside diameter × 16 mm width (0.787 × 1.024 × 0.63 in). From SKF catalogue PUB BU/P1 17000: radial dynamic rating C 8.42 kN, static C0 12.5 kN, fatigue limit Pu 1.4 kN, limiting speed 8,000 r/min, mass about 18 g.
What does HK 2016.2RS mean in SKF part numbering?
HK = open-end drawn cup needle roller bearing (ISO 3245); the first two digits give Fw 20 mm, the last two the width 16 mm, the shell OD 26 mm follows the plan. 2RS adds both-side contact seals, TN the polymer cage.
Does the HK 2016.2RS need a hardened and ground shaft?
No. In this execution the 20 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 2016.2RS?
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.
