HK4016.2RS Sealed Drawn Cup Needle Roller Bearing — 40 × 47 × 16 mm
HK4016.2RS is a sealed drawn cup needle roller bearing: 40 mm bore (Fw), 47 mm outside diameter, 16 mm outer ring width, seals on both sides and 37 g mass. It carries 14.5 kN dynamic and 27.5 kN static load, runs to 4 500 r/min and holds its grease for life — the lip seals keep dust out and the lubricant in, which is why this is the version most often specified for conveyors, agricultural linkages and outdoor equipment. The cup presses into a 47 mm housing bore and the shaft, hardened to 58–62 HRC, is the inner raceway. GCr15 rollers, P0/P6, from 100 pieces.

What Sealing Costs at 40 mm Bore
| Designation | Type | D × C (mm) | Cr (kN) | C0r (kN) | Limiting speed | Mass (kg) | Choose it when |
|---|---|---|---|---|---|---|---|
| HK 4012 | open | 47 × 12 | 13.4 | 24.5 | 7 000 | 0.03 | Minimum width, maximum speed |
| HK 4016 | open | 47 × 16 | 19 | 39 | 7 000 | 0.039 | Baseline: full capacity, needs relubrication |
| HK 4016.2RS | sealed both sides | 47 × 16 | 14.5 | 27.5 | 4 500 | 0.037 | Grease for life, dust excluded |
| HK 4018 RS | sealed one side | 47 × 18 | 19 | 39 | 4 500 | 0.045 | Full capacity kept, 2 mm wider |
| HK 4020 | open, wide | 47 × 20 | 24.2 | 53 | 7 000 | 0.054 | More load, needs grease access |
| HK 4020.2RS | sealed, wide | 47 × 20 | 19 | 39 | 4 500 | 0.048 | Sealed without losing much load |
| Change | Effect |
|---|---|
| Open → sealed both sides | Cr 19 → 14.5 kN (−24%), C0r 39 → 27.5 kN (−29%) |
| Limiting speed | 7 000 → 4 500 r/min (−36%) |
| Lubrication | Becomes life-lubricated — no relubrication route needed |
| Mass | 39 → 37 g (fewer, shorter rollers) |
| Shaft finish | The seal lip adds a second surface requirement |
Why capacity falls: the seals occupy axial space at each end, so a 16 mm wide sealed cup carries fewer rollers than the open cup of the same width. If you need both sealing and full capacity, step up to HK4018 RS (47 × 18, 19 kN, sealed one side) or HK4020.2RS (47 × 20, 19 kN, sealed both sides).

Six of these are sealed. At every bore, the sealed version trades roughly a quarter of its dynamic capacity and a third of its speed for dust exclusion and life lubrication — the ratio is consistent, which is why we publish both lines rather than a single "best" part.
Typical Applications
| Application | Why the 2RS version |
|---|---|
| Conveyor pulleys and idlers | Dust and grit, no relubrication point |
| Agricultural linkages and hubs | Mud, splash, infrequent maintenance |
| Outdoor power equipment | Weather exposure, life-lubricated |
| Food and packaging lines (dry side) | Washdown-adjacent, sealed against debris |
| Automotive and trailer components | Long service interval, grease retention |
| Industrial gearboxes, exposed shafts | Contamination path through the housing |
Shaft, Housing and Installation
- Shaft: 58–62 HRC, h5/h6, ground. The raceway needs Ra ≤ 0.2 µm; the seal lip is happier at 0.2–0.4 µm — a mirror finish can starve the lip and make it squeal.
- Housing: N7 press fit, R7 for thin-wall aluminium; chamfer 0.5 × 20° so the seal is not shaved on entry.
- Press on the outer cup only, with a flat arbor that clears the seal. Never press through the bore or rest the arbor on a seal.
- Do not wash a sealed unit in solvent — it removes the factory grease and the seal cannot be re-greased.
- Alignment: the seal tolerates less misalignment than the roller complement; keep angular error inside the housing's own tolerance.
- Speed: stay under 4 500 r/min; above that the lip generates heat faster than the cup can shed it.

Frequently Asked Questions
What are the dimensions of HK4016.2RS?
40 mm bore (Fw), 47 mm outside diameter, 16 mm width, sealed both sides, 37 g.
How much load does the seal cost?
Dynamic 19 → 14.5 kN (−24%) and static 39 → 27.5 kN (−29%) versus the open HK4016, with limiting speed falling from 7 000 to 4 500 r/min.
Is HK4016.2RS waterproof?
No. It excludes dust, chips and splash and retains grease, but it is not a pressure or immersion seal.
Does it need relubrication?
No. It is grease-filled for life at the factory. Do not solvent-wash it.
How fast can it run?
4 500 r/min limiting speed — the sealed version runs 36% slower than the open bearing.
Which designations are the same part?
HK4016.2RS, HK4016-2RS and HK40162RS all refer to this bearing; it also interchanges with the same code from INA/FAG, SKF, NTN, NSK and Koyo.
Sealed, or sealed with more load?
Tell us the duty — dust, splash, speed and load — and we will tell you whether HK4016.2RS is enough or whether HK4018 RS / HK4020.2RS buys you the capacity back. Price and lead time within 24 hours on working days.
