How the 2216-ETN9 model number is decoded
The 22xx series is the wide light-section self-aligning ball bearing (ISO dimension series 22). the last two digits encode the bore: 2216 carries code 16 = 80 mm (code × 5). Envelope 80×140×33 mm (3.15×5.512×1.299 in) with a 30.0 mm radial section height, C 65 kN, C0 25.5 kN and Pu 1.25 kN. The open 2216 ETN9 carries no shields or seals and relies on application lubrication and external sealing. The ETN9 suffix identifies the glass-fibre-reinforced polyamide 66 cage execution. The bore is cylindrical (straight), for a press-fit on a 80 mm shaft. Reference (thermal) speed 8500 r/min, limiting speed 6000 r/min, catalogue mass 2000 g.
Typical equipment & failure modes
Common applications
- industrial fans and blowers
- woodworking machinery
- pump shafts with mild misalignment
- material-handling equipment
Known failure patterns
- lubricant starvation where no regreasing interval is maintained
- contamination wear when the open arrangement is used without adequate external sealing
- false brinelling from vibration while the shaft stands idle
- fretting corrosion on a creeping shaft or housing seat
Selection pitfalls — read before you substitute
- Fillet radii must clear the 2216-ETN9 chamfer so the 33 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Fillet radii must clear the 2216-ETN9 chamfer so the 33 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- The ETN9 suffix on 2216-ETN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 6000 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Catalogue ratings for 2216-ETN9 (C 65 kN, C0 25.5 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
- Mount 2216-ETN9 by heating the inner ring (max 120 °C) on a cylindrical bore — driving it home through the outer ring or balls brinells the raceways.
- The fatigue load limit is 1.25 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
Frequently asked questions
What are the dimensions of 2216-ETN9?
SKF 2216 ETN9 measures 80 mm bore × 140 mm OD × 33 mm width (3.15 × 5.512 × 1.299 in), mass about 2000 g. It is open, with no shields or seals.
How does the bore code in 2216 work?
The final two digits of 2216 are bore code 16, multiplied by 5 to give 80 mm.
How much misalignment can 2216-ETN9 tolerate?
Self-aligning ball bearings tolerate roughly 2–3° of static misalignment for open executions; sealed 2RS1 variants like 2216-ETN9 allow less (about 1°) because the seal lip binds first.
Can 2216-ETN9 take axial load?
A self-aligning ball bearing can carry some axial load in addition to radial load, but its axial capacity is lower than an angular-contact bearing of the same envelope. Use it where misalignment, not thrust, is the main requirement.
