How the 6216-M model number is decoded
In the 6200-series, the last two digits encode the bore: 6216 carries code 16 = 80 mm (code × 5). The envelope is 80×140×26 mm (3.15×5.512×1.024 in) with a 30.0 mm radial section height, C 72.8 kN, C0 55 kN and Pu 2.2 kN. The open 6216 M carries no shields or seals and relies on application lubrication and external sealing. The M suffix identifies the machined brass cage execution, a separate order number from the pressed-steel version. Limiting speed 8500 r/min, catalogue mass 1700 g.
Typical equipment & failure modes
Common applications
- material-handling equipment
- industrial fans
- compressor drives
- machine tool auxiliaries
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- electrical pitting in VFD-driven motors without shaft grounding
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- The fatigue load limit is 2.2 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- Catalogue ratings for 6216-M (C 72.8 kN, C0 55 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.
- The M suffix on 6216-M denotes a machined brass cage: it is the choice for high speeds, marginal lubrication and shock/vibration duty, and it is temperature-tolerant where polymer cages are not — the 1700 g quoted mass includes the heavier cage.
- Open 6216-M needs external sealing at the arrangement level; in dusty housings its life depends entirely on those external seals and the regreasing schedule.
- Plan a relubrication interval for 6216-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Fillet radii must clear the 6216-M chamfer so the 26 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
Frequently asked questions
What are the dimensions of 6216-M?
The SKF 6216 M measures 80 mm bore × 140 mm OD × 26 mm width (3.15 × 5.512 × 1.024 in), mass about 1700 g. It is open, with no shields or seals.
How does the bore code in 6216 work?
The final two digits of 6216 are bore code 16, multiplied by 5 to give 80 mm.
What load can 6216-M take?
Catalogue values for 6216 M: dynamic C 72.8 kN, static C0 55 kN, fatigue limit Pu 2.2 kN. Use C in life calculation and C0 for static checks at 80 mm bore.
What is the speed rating of 6216-M?
SKF lists a 9500 r/min thermal reference speed and a 8500 r/min mechanical limiting speed for 6216 M; real limits also depend on lubrication and fits.
