How the HK1416F model number is decoded
NTN HK1416F belongs to the HK-series of open-end drawn-cup needle roller bearings (ISO 3245).Fw = 14 mm names the shaft journal that doubles as the inner raceway; around it the drawn cup measures 20 mm outside and 16 mm across. There is no separate inner ring — the thin-walled cup is drawn from sheet steel, hardened, and press-fitted into the housing, giving the smallest radial section of any rolling bearing at this shaft size. The F suffix marks NTN's caged drawn-cup execution: a formed steel cage spaces the rollers, lowering friction versus full-complement drawn cups. Drawn cups in this class are the default compact radial bearing in motorcycle and power-tool gearboxes, where housing space is the binding constraint. Office automation equipment — printers, copiers, paper feeders — uses this size in the transport rollers, where the open ends are enclosed by the chassis and relubrication is never planned. For vertical shafts, arrange the housing so the open end of the cup faces up or provides a grease reservoir below — gravity drains lubricant away from the roller set otherwise.
Typical equipment & failure modes
Common applications
- small hydraulic pump drives
- automotive accessory drives
- lawn and garden equipment spindles
- intermittent duty with long standstill periods that invite false brinelling
Known failure patterns
- brinelling of the drawn cup from hammer blows during press-in mounting
- grease starvation in the open-end arrangement with no relubrication path
- raceway spalling on a shaft that was below the required 58–64 HRC hardness
Selection pitfalls — read before you substitute
- Press the drawn cup in with a mandrel bearing on the stamped face only — never hammer the cup or press through the rollers, that cracks or brinells the shell.
- The rollers of HK1416F run directly on the 14 mm journal: any score mark, rust pit or plating flake on that surface becomes a raceway defect — dress or replace a marginal shaft.
- The cage in HK1416F guides the rollers but is not a seal: it retains nothing against dust or washdown, so the housing still needs its own sealing arrangement at 14 mm.
- The 16 mm standard width of HK1416F is the general-purpose section at 14 mm shaft; wider HK variants in the same 14×20 mm envelope carry more load and are not interchangeable if the housing width is fixed.
Frequently asked questions
How is a HK1416F retained in the housing?
The thin-walled drawn cup of HK1416F is press-fitted into a 20 mm housing bore (typically N6/N7 tolerance for steel housings). The press fit alone retains the cup — no snap rings or shoulders are needed, but the bore must be round and rigid.
What are the dimensions of a HK1416F needle roller bearing?
A HK1416F drawn-cup needle roller bearing has a 14 mm shaft diameter (Fw, under-roller diameter), 20 mm outside diameter and 16 mm width, per ISO 3245 boundary dimensions. It has no inner ring — the shaft journal serves as the raceway.
What does Fw mean on a HK1416F drawn-cup bearing?
Fw is the under-roller diameter — the diameter of the shaft journal on which the needle rollers run directly. For HK1416F, Fw = 14 mm, so the shaft must be machined to 14 mm, hardened to 58–64 HRC and ground, unless a separate IR inner ring is fitted.
Can a HK1416F needle roller bearing carry axial load?
No. Drawn-cup needle roller bearings like HK1416F carry radial load only and provide no axial shaft location. Axial forces must be carried by separate thrust washers or a locating bearing in the arrangement.
